Abstract:
Crouch gait is one of the most common gait abnormalities; it is usually caused by cerebral palsy. There are few works related to the modeling of crouch gait kinematics, crouch gait analysis, and visualization in both the workspace and joint space. In this work, we present a quaternion-based method to solve the forward kinematics of the position of the lower limbs during walking. For this purpose, we propose a modified eight-DoF human skeletal model. Using this model, we present a geometric method to calculate the gait inverse kinematics. Both methods are applied for gait analysis over normal, mild, and severe crouch gaits, respectively. A metric-based comparison of workspace and joint space for the three gaits for a gait cycle is conducted. In addition, gait visualization is performed using Autodesk Maya for the three anatomical planes. The obtained results allow us to determine the capabilities of the proposed methods to assess the performance of crouch gaits, using a normal pattern as a reference. Both forward and inverse kinematic methods could ultimately be applied in rehabilitation settings for the diagnosis and treatment of diseases derived from crouch gaits or other types of gait abnormalities.

Abstract:
Diabetic foot is an invalidating complication of diabetes mellitus, a chronic disease increasingly frequently encountered in the aging population. The global prevalence of diabetes is predicted to double by the year 2030 from 2.8% to 4.4%. The prevalence of foot ulceration among patients with diabetes mellitus ranges from 1.3% to 4.8%. Several studies have highlighted that biomechanical factors play a crucial role in the aetiology, treatment and prevention of diabetic foot ulcers. Recent literature on the diabetic foot indicates that mechanical stresses, high plantar pressures or/and high tangential stresses, acting within the soft tissues of the foot can contribute to the formation of neuropathic ulcers. While it is important to study the in-vivo diabetic foot-to-floor interactions during gait, models for simulations of deformations and stresses in the diabetic plantar pad are required to predict high risk areas or to investigate the performance of different insoles design for optimal pressure relief. The finite elements (FE) models allow taking into account the critical aspects of the diabetic foot, namely the movement, the morphology, the tissue properties and the loads. Several 2-dimensional (2D) and 3-dimensional (3D) foot models were developed recently to study the biomechanical behavior of the human foot and ankle. However, to the author knowledge, a geometrically detailed and subject specific 3D FE model of the diabetic neuropathic foot and ankle has not been reported. Furthermore 2D and 3D state-of-the-art FE foot models are rarely combined with subject specific gait analysis data both in term of ground reaction forces and kinematics as input parameters and plantar pressure for validation purposes. The purpose of the study herein presented was to simulate the biomechanical behavior of both an healthy and a diabetic neuropathic foot in order to predict the area characterized by excessive stresses on the plantar surface. To achieve this, it has been developed an FE model of the foot by means of applying the loading and boundary conditions given by subject-specific integrated and synchronized kinematic-kinetic data acquired during gait analysis trials to a subject specific FE model (geometry was obtained through subject specific magnetic resonance images - MRI). Thus, an integrated kinematic-kinetic protocol for gait analysis which evaluates 3D kinematics and kinetics of foot subsegments together with two comprehensive FE models of an healthy and a diabetic neuropathic foot and ankle were described herein. In order to establish the feasibility of the former approach, a 2D FE model of the hindfoot was first developed, taking into account the bone and plantar pad geometry, the soft tissues material properties, the kinematics and the kinetics of both an healthy and a diabetic neuropathic foot acquired during three different phases of the stance phase of gait. Once demonstrated the advantage of such an approach in developing 2D FE foot models, 3D FE models of the whole foot of the same subjects were developed and the simulations were run in several phases of the stance phase of gait The validation of the FE simulations were assessed by means of comparison between the simulated plantar pressure and the subject-specific experimental ones acquired during gait with respect to different phases of the stance phase of gait. A secondary aim of the study was to drive the healthy and the diabetic neuropathic FE foot models with the gait analysis data respectively of 10 healthy and 10 diabetic neuropathic subjects, in order to verify the possibility of extending the results of the subject specific FE model to a wider population. The validity of this approach was also established by comparison between the simulated plantar pressures and the subject-specific experimental ones acquired during gait with respect to different phases of the stance phase of gait. Comparison was also made between the errors evaluated when the FE models simulations was run with the subject specific geometry (obtained from MRI data) and the errors estimated when the FE simulations were run with the data of the 20 subjects
Il diabete mellito è una malattia cronica sempre più frequente. Fra le complicanze ad esso associate vi è il cosiddetto “piede diabetico”. L’incidenza del diabete a livello mondiale è destinata a raddoppiare entro il 2030 passando dal 2.8% al 4.4% della popolazione ed il numero di pazienti affetti da diabete mellito che sviluppano ulcera podalica oscilla tra l’1.3% ed il 4.8%. Numerosi studi hanno evidenziato come i fattori biomeccanici giochino un ruolo fondamentale nell’eziologia, nel trattamento e nella prevenzione delle ulcere del piede diabetico. La letteratura recente sul piede diabetico indica che le sollecitazioni meccaniche, ossia le elevate pressioni plantari e/o gli elevati sforzi tangenziali, che agiscono all’interno dei tessuti molli del piede possono contribuire alla formazione di ulcere. È quindi importante studiare le interazioni piede-suolo durante il cammino nei pazienti diabetici, ma si rendono anche necessari dei modelli per la simulazione di sollecitazioni e deformazioni nel tessuto plantare del piede diabetico che permettano di predire le aree ad alto rischio di ulcerazione o di valutare l’efficacia di ortesi plantari nel ridistribuire in modo ottimale le pressioni plantari. I modelli agli elementi finiti consentono di tenere conto degli aspetti critici del piede diabetico, vale a dire il movimento, la morfologia, le proprietà dei tessuti e le sollecitazioni meccaniche. Di recente sono stati sviluppati diversi modelli bidimensionali (2D) e tridimensionali (3D) del piede con lo scopo di studiare il comportamento biomeccanico di piede e caviglia. Tuttavia, per quanto appurato dall’autore, in letteratura non è stato riportato un modello 3D agli elementi finiti del piede diabetico neuropatico con geometria dettagliata e specifica di un soggetto. Inoltre, i modelli 2D e 3D agli elementi finiti del piede presenti in letteratura sono stati raramente combinati con i dati del cammino specifici dei soggetti, sia in termini di forze di reazione al suolo e cinematica (come parametri di input) che in termini di pressioni plantari per la validazione. L’obiettivo dello studio qui presentato è stato quello di simulare il comportamento biomeccanico sia del piede di un soggetto sano che del piede di un soggetto diabetico neuropatico per prevedere l'area della superficie plantare caratterizzata da eccessive sollecitazioni. A tal scopo, sono stati sviluppati due modelli agli elementi finiti di piede e caviglia, utilizzando le geometrie specifiche dei piedi dei due soggetti (uno sano ed uno diabetico neuropatico) ottenute attraverso immagini di risonanza magnetica (MRI). Quindi sono state effettuate delle simulazioni mediante l'applicazione di carichi e di condizioni al contorno, ottenuti da dati di cinematica e cinetica, integrati e sincronizzati, acquisiti durante il cammino, specifici dei due soggetti sui rispettivi modelli agli elementi finiti. Pertanto in questa tesi sono stati descritti un protocollo integrato di cinematica-cinetica per l'analisi del cammino che permette di valutare la cinematica e la cinetica 3D dei sottosegmenti del piede e due modelli completi agli elementi finiti di un piede sano e di un piede diabetico neuropatico. Per stabilire la fattibilità di tale approccio, sono stati inizialmente sviluppati due modelli 2D agli elementi finiti del retropiede di un soggetto sano e di un soggetto diabetico neuropatico, tenendo conto della geometria ossea e del cuscinetto plantare, delle proprietà dei materiali dei tessuti molli, della cinematica e della cinetica. Questi ultimi sono stati acquisiti durante tre istanti della fase di appoggio del ciclo del passo. Una volta dimostrato il vantaggio di un simile approccio nello sviluppo di modelli 2D agli elementi finiti del piede, sono stati sviluppati i modelli 3D agli elementi finiti del piede intero degli stessi soggetti e sono state eseguite le simulazioni in vari istanti della fase di appoggio. La validazione delle simulazioni è stata effettuata attraverso il confronto tra le pressioni plantari simulate e quelle acquisite sperimentalmente durante il cammino degli stessi soggetti, nei corrispondenti istanti della fase di appoggio. Un secondo scopo dello studio qui presentato è stato quello di effettuare simulazioni del modello del piede del soggetto sano e di quello del soggetto neuropatico con dati di analisi del cammino rispettivamente di 10 soggetti sani e 10 diabetici neuropatici, al fine di verificare la possibilità di estendere i risultati dei modelli specifici dei due soggetti ad una popolazione più ampia. La validità di questo approccio è stata valutata tramite il confronto tra le pressioni plantari simulate e quelle sperimentali specifiche di ogni soggetto, acquisite durante il cammino. Inoltre gli errori delle simulazioni eseguite con i dati dei 20 soggetti sono stati confrontati con gli errori effettuati quando le simulazioni dei modelli avevano previsto l’utilizzo di dati di cammino specifici dei due soggetti la cui geometria podalica era stata ottenuta da MRI

Abstract:
L'analisi del cammino è definita come lo studio sistematico della locomozione umana. Una parte centrale dell'analisi del cammino è rappresentata dall'elettromiografia di superficie (sEMG). Un ruolo centrale nel controllo del cammino è svolto dai muscoli degli arti inferiori, e in particolare dalla co-contrazione muscolare degli arti inferiori. La co-contrazione muscolare è definita come il reclutamento concomitante di muscoli antagonisti che afferiscono a un determinato giunto. In soggetti sani, la co-contrazione esercita una pressione omogenea sulla superficie articolare, preservandone la stabilità articolare. In individui patologici, la co-contrazione sembra avere un ruolo chiave nello sviluppo di strategie di compensazione durante la riabilitazione motoria. Per la quantificazione dell'attività di co contrazione dei muscoli degli arti inferiori, diverse metodologie basate su sEMG sono state sviluppate ma uno standard per identificare la co-contrazione muscolare non è ancora disponibile. Dunque, obiettivo è l'analisi della co contrazione dei muscoli delle gambe nel dominio tempo-frequenza durante il cammino e la determinazione di dati normativi durante il cammino sano adulto e pediatrico. L'analisi mediante trasformata Wavelet (WT) è uno strumento appropriato per sviluppare un nuovo approccio per la valutazione della co-contrazione muscolare nel dominio tempo frequenza. Il metodo proposto è denominato CODE: CO-contraction DEtection. Un'ulteriore applicazione dell'analisi WT è l'estrazione e la valutazione dei suoni cardiaci fetali, dal segnale fonocardiografico fetale. Per ottenere dati di riferimento sulla co-contrazione dei muscoli dell’arto inferiore durante il cammino adulto e pediatrico è stata utilizzata la Statistical Gait Analysis (SGA), tecnica recente in grado di fornire una caratterizzazione statistica del cammino, calcolando i parametri spaziali-temporali mediante l’analisi di centinaia di passi di uno stesso soggetto durante il cammino.
Gait analysis is the systematic study of human locomotion. A central part of gait analysis is represented by surface electromyography (sEMG). The walking control is played by lower limb muscles, and in particular by lower limb muscular co-contraction. Muscular co-contraction is the concomitant recruitment of antagonist muscles crossing a joint. In healthy subjects, co-contraction occurs to achieve a homogeneous pressure on joint surface, preserving articular stability. In pathological individuals, the assessment of co-contraction appeared to have a key role for discriminating dysfunction conditions of the central nervous system. Different methodologies for muscular co-contraction assessment were developed. A co-contraction index (CI) based on the area computation under the curve of rectified EMG signal from antagonist muscles was developed. It provides an overall numerical index that could not be suitable to characterize dynamic task. To overcome this limitation, muscular co-contraction was assessed by overlapping linear envelopes or temporal interval where muscles superimposed. Thus, a gold standard for identifying muscle co-contraction is not available yet. The aim of the study is to perform an EMG-based analysis of muscular co-contraction by proposing a new and reliable techniques for leg-muscle co-contraction assessment in time-frequency domain and by providing normative co-contraction data during heathy adult and child walking. The proposed method, based on Wavelet transform (WT), is named CO-contraction DEtection algorithm (CODE). A further application of WT analysis is the extraction and assessment of fetal heart sounds, from fetal phonocardiography signal. In the present study, also a reference data on lower-limb-muscle co contraction was provided by means of Statistical Gait Analysis, a technique able to provide a statistical characterization of gait, by averaging spatial-temporal and sEMG-based parameters over hundreds of strides during walking.

Abstract:
Within sports and health sciences, the biomechanical study of human movement has many purposes, including rehabilitation, injury prevention and performance analysis. While in clinical biomechanics the main goal is to determine if a motion is physiological or if it differs from normal values, in the sports context the aim is finding the movement determinants that allows an athlete to perform at the highest possible level. Research in movement analysis is nowadays supported by multi-camera stereophotogrammetric systems, used to reconstruct three-dimensional body landmarks coordinates from video images. These allow the collection of quantitative information about the mechanics of the musculo-skeletal system during the execution of a motor task. In particular, the following quantities will be considered: the kinematics of the whole-body centre of mass (CoM); the relative movement between adjacent bones (joint kinematics); body segment energy variation and muscular work. The current thesis contains the main experimental projects of my doctoral research activity. Many performance analyses were based on the estimation of the kinematics of the body CoM, whose reliability was demonstrated with a reduced marker set, which is desirable when dealing with complex movements. Inspecting CoM kinematics gives the researcher a complete view of the athletes’ movements, with a insight on balance and motor control: we found that expert karateka, who are supposed to possess superior balance abilities, perform the same fighting sequence with a lower CoM as compared with amateur practitioners. We also found that the strategy adopted by young soccer players to be faster in a slalom dribbling task consists in the optimization of CoM path throughout the course, i.e. in a more sophisticated motor control. The inspection of joint kinematics allows to assess the functioning of kinetic chains, i.e. proximal-to-distal linkage between segments, and to understand the phases of complex multi-segmental techniques: in soccer pass-kick we identified laterality-driven differences between the preferred and non-preferred side. Kinematic curves, as well as gait cycle parameters like step width, length or cadence, helped in identifying locomotion issues in a patient wearing a knee endoprosthesis. An emerging and stimulating challenge in motion analysis is the extraction of distinct features from the large amount of available kinematic data: two are symmetry and variability. Symmetry indexes were applied to assess the effects of a physiotherapy intervention on a prosthetic patient, while a novel repeatability index was developed for mandibular joint motion. Additionally, multivariate statistical techniques like the Principal Components Analysis allowed for the identification of abnormal gait patterns in urologic patients, as well as for the extraction of fundamental motor modules from complex sports skill in soccer and elite karate athletes.

Abstract:
Two methods were used in this research. The pedobarograph is a relatively novel method of gait analysis for animals which enables footfall patterns to be recorded, enabling spatial parameters (step length, width and angle) and plantar pressure patterns to be described and measured. A Kistler force plate was then used to measure the three-dimensional ground reaction forces (GRF's) produced during walking. Speed and cadence can be calculated using either system. Gait patterns are described for normal birds, and for different strains of broilers, raised on different feeding regimes. All the gait parameters were very variable, both between birds, and within the same bird, even when bodyweight and speed were controlled for. Despite the high variability, however, significant differences were identified in many of the gait parameters between the different groups. The vertical and craniocaudal GRF's of Brown Leghorns showed similar characteristics to those produced in human walking. The peak vertical forces were of a similar order of magnitude in the birds as in humans (125-150 % bodyweight), and the peak craniocaudal forces, and the rate of change of force, were closely tied to speed. All the GRF's in the birds increased significantly with increasing speed, except for braking rate (which was more variable) and stance time (which decreased significantly). The mediolateral forces were much greater in the birds than have been reported for other species, however, with peaks of 10-22% bodyweight. Analysis of plantar pressures showed that the pressure were concentrated on the digital pads, with the lowest pressure on the metatarsal pad (131 kNm-2), and highest pressure on the medial toe (up to 218 kNm-2).Combined gait analysis and morphometric studies of ad libitum-fed selected broilers identified many ways in which their gait deviated from that of relaxed broilers and Brown Leghorns, in ways which would serve to increase stability and decrease stresses on the skeleton.

Abstract:
This master’s thesis project “Instrumentation of Gait Analysis” was carried out at and funded by Integrum AB, Gothenburg, Sweden. Force analysis is critical during rehabilitation process of amputation patients, since overloading might place the bone-implant interface at risk; while underloading might extend unnecessarily the already long rehabilitation program [1]. Highly developed sensor and data acquisition technology provides an easy and reliable way to do force analysis. This thesis introduces the problem and provides background material regarding Orthotics and Prosthetics, including osseointegration. The existing gait analysis techniques and sensor technology will be described. Based upon the criteria that are introduced, a suitable sensor and integration platform was selected to implement a new gait analysis system. Several trials of different gait states are proposed using the prototype to do gait analysis, the results are presented and analyzed. The success of this prototype has lead to plans to design an Osseointegrated Prostheses for the Rehabilitation of Amputees(OPRA) product

This thesis describes a representation of gait appearance for the purpose of person identification and classification. This gait representation is based on simple localized image features such as moments extracted from orthogonal view video silhouettes of human walking motion. A suite of time-integration methods, spanning a range of coarseness of time aggregation and modeling of feature distributions, are applied to these image features to create a suite of gait sequence representations. Despite their simplicity, the resulting feature vectors contain enough information to perform well on human identification and gender classification tasks. We demonstrate the accuracy of recognition on gait video sequences collected over different days and times, and under varying lighting environments. Each of the integration methods are investigated for their advantages and disadvantages. An improved gait representation is built based on our experiences with the initial set of gait representations. In addition, we show gender classification results using our gait appearance features, the effect of our heuristic feature selection method, and the significance of individual features.

Abstract:
Human gait identification has become an active area of research due to increased security requirements. Human gait identification is a potential new tool for identifying individuals beyond traditional methods. The emergence of motion capture techniques provided a chance of high accuracy in identification because completely recorded gait information can be recorded compared with security cameras. The aim of this research was to build a practical method of gait identification and investigate the individual characteristics of gait. For this purpose, a gait identification approach was proposed, identification results were compared by different methods, and several studies about the individual characteristics of gait were performed. This research included the following: (1) a novel, effective set of gait features were proposed; (2) gait signatures were extracted by three different methods: statistical method, principal component analysis, and Fourier expansion method; (3) gait identification results were compared by these different methods; (4) two indicators were proposed to evaluate gait features for identification; (5) novel and clear definitions of gait phases and gait cycle were proposed; (6) gait features were investigated by gait phases; (7) principal component analysis and the fixing root method were used to elucidate which features were used to represent gait and why; (8) gait similarity was investigated; (9) gait attractiveness was investigated. This research proposed an efficient framework for identifying individuals from gait via a novel feature set based on 3D motion capture data. A novel evaluating method of gait signatures for identification was proposed. Three different gait signature extraction methods were applied and compared. The average identification rate was over 93%, with the best result close to 100%. This research also proposed a novel dividing method of gait phases, and the different appearances of gait features in eight gait phases were investigated. This research identified the similarities and asymmetric appearances between left body movement and right body movement in gait based on the proposed gait phase dividing method. This research also initiated an analysing method for gait features extraction by the fixing root method. A prediction model of gait attractiveness was built with reasonable accuracy by principal component analysis and linear regression of natural logarithm of parameters. A systematic relationship was observed between the motions of individual markers and the attractiveness ratings. The lower legs and feet were extracted as features of attractiveness by the fixing root method. As an extension of gait research, human seated motion was also investigated.

Abstract:
In the present Thesis, walking was analyzed at various velocities in healthy participants, adults and children, on a split-belt treadmill mounted on 3D force sensors. Each belt can rotate at a different velocity, thus inducing artificial claudication. Conventional kinematic (optoelectronic) and surface EMG recordings from several lower limbs muscles were conducted. This experimental setting allowed to investigate both the motion of the body system as a whole (represented by its centre of mass, CoM) and the power provided by lower limb muscles (mostly, the plantar flexors). Various branches of an experimental campaign demonstrated that: a) a lateral shrinking of the CoM path is demonstrated with increasing age in children from 5 to 13 years. The lateral CoM oscillation/velocity function looks like a promising index of neural maturation. b) In adults, the 3D trajectory of the CoM implies a sharp U-turn (radius of curvature as small as 2 mm) at the beginning of the left-to-right (or vice-versa) oscillation, implying demanding muscular coordination. This curvature looks like a promising index of balance during walking. c) The claudication induced by “split” walking causes temporal asymmetries (“escape limp”) analogous to those found in pathologic claudication (shorter stance time, on the faster belt) but opposite spatial and dynamic asymmetries (longer posterior step and higher pantar flexors’ power, on the faster belt). d) The average velocity of the CoM on split-belt treadmills is different from the mean velocity between the belts. This velocity depends on the time spent by the point of application of the resulting ground reaction force on either belt. This implies that errors were made in the Literature, comparing split walking with tied walking at the mean velocity between the two belts. e) A representative unilaterally paretic patient has been analyzed to give an idea of the feasibility and the potential usefulness of the combined segmental and CoM analysis on split-belt treadmills. Overall, the series of experiments paves the way to a more soundly based analysis of pathologic gaits.

Abstract:
This thesis analyzes the human action recognition problem. Human actions are modeled as a time evolving temporal texture. Gabor filters, which are proved to be a robust 2D texture representation tool by detecting spatial points with high variation, is extended to 3D domain to capture motion texture features. A well known filtering algorithm and a recent unsupervised clustering algorithm, the Genetic Chromodynamics, are combined to select salient spatio-temporal features of the temporal texture and to segment the activity sequence into temporal texture primitives. Each activity sequence is represented as a composition of temporal texture primitives with its salient spatio-temporal features, which are also the symbols of our codebook. To overcome temporal variation between different performances of the same action, a Profile Hidden Markov Model is applied with Viterbi Path Counting (ensemble training). Not only parameters and structure but also codebook is learned during training.

Abstract:
In recent years, snake-inspired locomotion has garnered increasing interest in the bio-inspired robotics community. This positive trend is largely due to the unique and highly effective gaits utilized by snakes to traverse various terrains and obstacles. These gaits make use of a snake’s hyper-redundant body structure to adapt to the terrain and maneuver through tight spaces. Snake-inspired robots utilizing rectilinear motion, one of the primary gaits observed in natural snakes, have demonstrated favorable results on various terrains. However, previous variations of the rectilinear gait were inefficient in cyclic displacement. These gaits generated vertical waves traveling along the length of the robot. Generating these waves required significant joint energy for relatively small horizontal displacements. This paper presents analytical and experimental results for a rectilinear gait, which demonstrates significant linear displacement for relatively low joint effort. The low effort gait functions by propagating a wave through the length of the robot via expansions and contractions of the body segments, propelling the robot platform forward. The low effort rectilinear gait is demonstrated on a robot platform that incorporates high speed linear motion and variable traction through friction. We also report the results of a case study showcasing the practical benefits of the low effort gait.

Abstract:
We present the design and gait generation for an experimental ROLLERBLADER. The ROLLERBLADER is a robot with a central platform mounted on omnidirectional casters and two 3 degree of freedom legs. A set of passive rollerblading wheels is attached to the end of each leg. The wheels give rise to nonholonomic constraints acting on the robot. The legs can be picked up and placed back on the ground allowing a combination of skating and walking gaits. We present two types of gaits for the robot. In the first gait, the legs are picked up and placed back on the ground. In the second gait, the wheels stay on the ground at all times. Experimental gait results for a prototype robot are also presented.

Abstract:
This paper presents work on the gait and gait transition analysis for a novel mobile robot that uses two actuated spoke wheels. Gait transitions, known as acyclic feed forward patterns, allow the robot to switch from one type of gait to another during walking and turning. The mobile robot IMPASS (Intelligent Mobility Platform with Active Spoke System) uses a unique mobility concept for locomotion, thus gait transition plays an important role in generating gait patterns to walk and turn. The primary focus of this paper is how to perform gait transition between gaits in walking direction. First, the basic gait patterns for steering and straight line walking are presented. More specifically, the critical gait parameterizations and the possible foot positions in different gait patterns to produce capable steering locomotion over terrain are presented. Since IMPASS is expected to utilize its metamorphic configurations to carry out gait transitions, the extending forward and inverse analyses are also presented based on previous work about topology classification and mobility analysis for IMPASS. Then the gait transition analysis and simulation of typical patterns are performed. The results from this work lay the foundation for the future research on trajectory and path planning for IMPASS.

Abstract:
Snake-inspired locomotion is much more maneuverable compared to conventional locomotion concepts and it enables a robot to navigate through rough terrain. A rectilinear gait is quite flexible and has the following benefits: functionality on a wide variety of terrains, enables a highly stable robot platform, and provides pure undulatory motion without passive wheels. These benefits make rectilinear gaits especially suitable for search and rescue applications. However, previous robot designs utilizing rectilinear gaits were slow in speed. This paper introduces a new class of rectilinear gaits to be utilized by a snake-inspired robot design which is capable of pure linear motion and variable traction. The general model for the gait class is based on serial robot dynamics using the Lagrangian formulation. The gait class includes four unique gaits: a forward and a turning gait, which both emphasize speed for the robot; and a forward and turning gait which emphasize traction. Also, we perform an analysis of the variable traction concept.

Abstract:
This report analyzes the current service level of winter operations in Indiana and explores opportunities to optimize performance. We analyze data regarding winter operations managed by INDOT and provide specific quantified estimates of opportunities to improve efficiency while also managing costs. For our exploration, we use data provided by INDOT sources, qualitative insights from interviews with INDOT personnel, literature survey data and benchmarking information, salt and supplier data analysis, and simulation. As part of our research, we developed a simulation model to visually represent the impact of alternate management of trucks for snow removal and a dashboard to understand the impact. Our analysis suggests the following: (1) opportunities exist to coordinate salt delivery by suppliers and combine local city salt purchases with INDOT’s purchases to save costs, (2) adjusting routes will reduce deadhead, (3) understanding truck maintenance and truck locations improves performance, and (4) incorporating critical locations into snow route planning will meet service thresholds. These insights provide implementable recommendation initiatives to improve winter operations performance. The simulation tool developed in this project simulates various weather events to draw insights and determine appropriate resource allocations and opportunities for improving operational efficiency. The report thus provides a quantifiable approach to winter operations that can improve the overall service level and efficiency of the process.
