Abstract:
As an autonomic and convenient assistance device for people with disabilities and the elderly climbing up and down stairs, electric-powered wheelchairs with stair-climbing ability have attracted great attention in the past two decades and some various electric-powered wheelchairs with stair-climbing were developed. By using the developed electric-powered wheelchairs with stair-climbing, many patients with walking difficulties are able to descend the stairs conveniently to participate in outdoor activities, which are beneficial to both their physical rehabilitation and mental health. In this article, a review of electric-powered wheelchair with stair-climbing current technology is given and its future tendency is discussed to inform electric-powered wheelchair with stair-climbing researchers in the development of more applicable and popular products. Firstly, the development history is reviewed and electric-powered wheelchairs with stair-climbing are classified based on an analysis of their stair-climbing mechanisms. The respective advantages and disadvantages of different types of electric-powered wheelchairs with stair-climbing are outlined for an overall comparison of the control method, cost of mechanical manufacture, energy consumption, and adaption to different stairs. Insights into the future direction of stability during stair-climbing are discussed as it is an important aspect common to all electric-powered wheelchairs with stair-climbing. Finally, a summary of electric-powered wheelchairs with stair-climbing discussed in this article is provided. As a special review to the electric-powered wheelchairs with stair-climbing, it can provide a comprehensive understanding of the current technology about electric-powered wheelchairs with stair-climbing and serve as a reference for the development of new electric-powered wheelchairs with stair-climbing.

Abstract:
The article deals with the issues of operating wheelchairs with manual drive in areas with a significant inclination angle. The kinematics of a wheelchair while climbing a hill was analyzed. On the basis of the conclusions drawn from the research, two solutions for systems that block the reversal of a wheelchair on a hill have been proposed. Among the solutions mentioned, a mechanical anti-rollback system with three operating modes and an electric anti-rollback system is described. The described electric anti-rollback system is part of a manual-electric hybrid drive unit to the manual wheelchairs.

Abstract:
We studied the problem of interaction of movement between the electric wheelchair and the user. Almost all current products have indexes such as roll stability and operability, but such indexes do not always agree with user behavior because such indexes are static. Another problem arises from the fact that the disagreement of movement causes uncontrollable situations and turnover of the wheelchairs. We evaluated wheelchairs that consider user behavior, first in an experiment to understand the cause of disagreement among users during movement by measuring straight line ands turning, then, based on this result, derived a mathematical model for disagreement in wheelchair motion. Computer simulation, showed that vibration occurred within certain parameters. We present simple roll stability analysis of wheelchairs turning. Simulation confirmed the viability of our proposals.

Abstract:
Because a large number of accidents with electric wheelchairs are due to operational errors, steering assistance systems for wheelchairs have been studied in a variety of ways. One of the basic systems is 3-D obstacle detection around the wheelchair. One method uses a stereo camera for detecting obstacles by image processing. However, this method is less reliable under varying light conditions. A laser range sensor is another useful device for obstacle detection. However, it requires a complex swinging mechanism for 3-D positioning which makes the measuring time too long. Therefore, this paper presents a 3-D obstacle detection system for electric wheelchairs using a 2-D laser range sensor. We set up only one 2-D laser range sensor over the wheelchair, and attached mirrors around it to reflect the laser light obliquely downwards. Then, we gathered obstacle points while the electric wheelchair was moving and made a 3-D obstacle map to assist steering. We built a prototype device and confirmed by experimentation that it is able to detect obstacles in 3-D.

Abstract:
In today’s world there are many disabled persons who find it difficult to perform movements or perform daily activities. This types of persons are mainly dependent on others for their assistance. But they can become self-independent and perform some daily activities on their own with the help of assistive devices. The most widely used assistive devices are Wheelchairs. Wheelchairs is basically a chair fitted with wheels, which can help people move around who cannot walk because of illness, disability or injury. But there are many disabled people with weak limbs and joints who cannot move the wheelchair. Thus, Smart Wheelchair can benefit a lot to them and everyone in society. Smart Wheelchairs are electric powered wheelchairs with many extra components such as a computer and sensors which help the user or guardian accompanying wheelchair to handle it easily and efficiently. The recent development in the field of Artificial Intelligence, Sensor technologies and Robotics help the growth of wheelchairs with new features. This paper is to review the current state of art of Smart Wheelchairs and discuss the future research in this field.

Abstract:
Electric wheelchairs are designed to aid paraplegics. Unfortunately, these can not be used by persons with higher degree of impairment, such as quadriplegics, i.e. persons that, due to age or illness, can not move any of the body parts, except of the head. Medical devices designed to help them are very complicated, rare and expensive. In this paper a microcontroller system that enables standard electric wheelchair control by head motion is presented. The system comprises electronic and mechanic components. A novel head motion recognition technique based on accelerometer data processing is designed. The wheelchair joystick is controlled by the system?s mechanical actuator. The system can be used with several different types of standard electric wheelchairs. It is tested and verified through an experiment performed within this paper.

Abstract:
Wheelchairs are used by people having difficulty in walking due to disability or some illness. The wheelchairs can either be self-propelled or can be moved by using the torque developed from the electric motors fitted to the wheels. The use of automated wheelchairs has largely increased as it does not require any muscular movement from the user. The various automated wheelchair models available in the market are of high cost and cannot be afforded by everyone in need. In this project, we aim to develop a low cost automated wheelchairWithout compromising its reliability. The wheelchair movement is controlled by the user via a thumb joystick. The control algorithm is implemented by using ATMEGA 328P.

Abstract:
<p class="0abstract">Quadriplegia is a paralysis condition in both arms and legs so that the patient is only able to move his neck and head. Manual or electric wheelchairs with joystick or switch control as a tool for people with paralysis certainly cannot be controlled independently by quadriplegia sufferers. This study aimed to help quadriplegia sufferers not to depend on others in carrying out daily activities by developing electric wheelchairs that can be controlled independently. The bioelectric signal which has only been used for diagnostic purposes can be utilized as an electric wheelchair control system for quadriplegia sufferers. In this study, electric wheelchairs were controlled by electromyography (EMG) signals from muscle contractions that can be driven by quadriplegia sufferers, namely the neck and face muscles. The increase in EMG signal amplitude during the muscle contraction is used as a trigger for the electric motor in a wheelchair to move forward, backward, turn right, and turn left. An electronic circuit for signal conditioning was used to amplify the EMG signal leads and filter frequencies that are not needed by the system before being processed by the microcontroller circuit. The use of wireless systems was developed to reduce the use of cables connecting electrodes to patients with electronic devices that will provide comfort to the user. Based on the results of the data collection on the wheelchair system, the detectability and selectivity values were for the 100% and 94% forward commands, 94.33% and 100% reverse commands, 92.31%, and 96% right turn commands and 97.96% and 94.12% left turn commands. The electric wheelchair system with EMG signal control is expected to help the mobility of quadriplegia sufferers.</p>

Abstract:
An electric wheelchair is the device to support the self-movement of the elderly and people with physical disabilities. In this paper, a prototype design of an electric wheelchair with a high level of mobility and safety is presented. The electric wheelchair has a high level of mobility by employing an omnidirectional mechanism. Large numbers of mechanisms have been developed to realize omnidirectional motion. However, they have various drawbacks such as a complicated mechanism and difficulty of employment for practical use. Although the ball wheel drive mechanism is simple, it realizes stable motion when negotiating a step, gap, or slope. The high level of mobility enhances the freedom of users while increasing the risk of collision with obstacles or walls. To prevent collisions with obstacles, some electric wheelchairs are equipped with infrared sensors, ultrasonic sensors, laser range finders, or machine vision. However, since these devices are expensive, it will be difficult for them to be widely used with electric wheelchairs. We have developed a prototype design of collision-detecting device with inexpensive sensors. This device detects the occurrence of collisions and can calculate the direction of the colliding object. A prototype has been developed to perform motion experiments and verify the accuracy of the device. The results of experiments are also presented in this paper.

Abstract:
While the active dynamic stability of automobiles has increased over the past 17 years there have been very few similar advances made with electrically powered wheelchairs. This lack of improvement has led to a long standing acceptance of less-than-optimal stability and control of these wheelchairs. Accidents due to loss of stability are well documented. Hence, the healthcare industry has made several efforts for improved control of electric powered wheelchairs (EPWs) to provide enhanced comfort, safety and manoeuvrability at a lower cost. In response, an area of stability control was identified that could benefit from a feedback control system using solid state sensors. To design an effective closed–loop feedback controller with optimal performance to overcome instabilities, an accurate model of wheelchair dynamics needed to be created. Such a model can be employed to test various controllers quickly and repeatedly, without the difficulties of physically setting a wheelchair up for each test. This task was one central goal of this research. A wireless test-bed of a front wheel drive (FWD) wheelchair was also developed to validate a dynamic wheelchair model. It integrates sensors, a data control system, an embedded controller, and the motorised mechanical system. The wireless communication ensures the integrity of sensor data collected and control signals sent. The test-bed developed not only facilitates the development of feedback controllers of motorised wheelchairs, but the collected data can also be used to confirm theories of causes of dynamic instabilities. The prototype test-bed performed the required tasks to satisfaction as defined by the sponsor. Data collected from live tests in which the test-bed followed set patterns, was processed and analysed. The patterns were designed to induce instability. The analysis revealed that an occupied wheelchair is more stable than an unoccupied wheelchair, disproving an initial instability theory proposed in this research. However, a proximal theory explaining over-steer is confirmed. Two models of the FWD test-bed were created. First, a dynamic model inherited from prior research, based on equations of motion was tested and enhanced based on measured data. However, even with alterations to correct parameter values and variables in the equations, a complete model validation was not possible. Second, a kinematic model was created with a factor to compensate for dynamics not normally accounted in kinematic models. The kinematic model was partially validated versus the measured data. Although, still highly accurate, there is room for improvement in this model. Both models contained a sub-system drive motor model, to account for input forces to the FWD wheelchair system model, which is fully validated.

Abstract:
Le fauteuil roulant électrique constitue un moyen efficace permettant de retrouver une certaine mobilité pour de nombreuses personnes dans le monde. Malheureusement, certaines personnes en situation de handicap moteur et atteintes d’une perte de force musculaire peuvent avoir du mal à utiliser un fauteuil roulant électrique à cause de difficultés liées au maniement du joystick, dispositif usuel de pilotage du fauteuil. Cette thèse vise à proposer explorer une alternative au joystick pour des personnes atteintes de maladies neuromusculaires. Le travail de cette thèse s’intéresse plus particulièrement à l’interaction tactile. L’hypothèse est que l’interaction tactile peut offrir un pilotage fiable avec un niveau d’effort physique qui est tolérable par des personnes atteintes de maladies neuromusculaires. Dans cette perspective, nous avons développé une interface sur smartphone de pilotage de fauteuil roulant électrique qui offre de nombreuses possibilités de paramétrage permettant de la personnaliser selon le besoin de la personne. Cette interface a été conçue dans une démarche itérative centrée utilisateur. Dans chaque itération, différentes personnes souffrant d’une perte de mobilité ont pu tester l’interface de pilotage. Leurs retours alimentent les améliorations à apporter à l’interface dans l’itération d’après. Lors de la dernière itération dans le cadre de cette thèse, Une étude a été menée avec des utilisateurs atteints de maladies neuromusculaires au SSR le Brasset, avec l’aide de l’AFM Théléton. Ces participants ont pu s’approprier l’interface tactile et l’utiliser pour piloter leurs fauteuils roulants. Nous avons également comparé les performances de pilotage en utilisant l’interface tactile et le joystick dans différentes tâches quotidiennes (virage, slalom...). Les performances de ces patients avec l’interface tactile sont proches de celles du joystick. Par ailleurs, les remarques récoltées suggèrent que l’interface tactile exige moins d’effort physique que le joystick
The power wheelchair is an effective way to regain mobility for many people around the world. Unfortunately, some people with motor disabilities who also suffer from loss of muscle strength may find it difficult to use a power wheelchair. The reason is that they can experience difficulties related to the handling of a joystick, the standard wheelchair control device. This thesis aims to propose exploring an alternative to the joystick for people with neuromuscular diseases. The work of this thesis is particularly interested in tactile interaction. The hypothesis is that the tactile interaction can offer a reliable control with a level of physical effort which is tolerable by people suffering from neuromuscular diseases. In this perspective, we developed a wheelchair steering interface on smartphone. It offers many configuration possibilities allowing the customization according to the user's needs. This interface was designed in a user-centered, iterative approach. In each iteration, different people suffering from a loss of mobility were able to test the piloting interface. Their feedback feeds into improvements to the interface in the next iteration. During the last iteration as part of this thesis, a study was carried out with users suffering from neuromuscular diseases at the SSR Le Brasset, with the help of the AFM Théléton. These participants were able to take appropriate the use of the touch interface and use it to control their wheelchairs. We also compared the driving performance using the touch interface and the joystick in different daily tasks (cornering, slalom ...). The performance of these patients with the touch interface is close to that of the joystick. In addition, the comments collected suggest that the touch interface requires less physical effort than the joystick

Abstract:
A sedentary lifestyle can induce health related problems including pressure ulcers. Pro­longed sitting inadequacies constitute a risk for pressure ulcer to many individuals, in particular people with disabilities and re­duced mobility. The measurement of distributed pressure and detection of irregular sitting postures are essential in prevention of the risk of developing pres­sure ulcers. In this thesis, a screen-printed pressure sensor for a large area is presented, with the objective of measuring the distributed pressure of a seated per­son in a wheelchair. The conductors and interdigital patterns are printed with silver-based ink. A blend of a non-conductive and a low resis­tive ink is used for customized resistance for an optimal sensing range of the pressure sensor. The effect of moisture and temper­ature are realized in an environment chamber. For characterization, other key performance tests such as repeatability, drift and flexibility are carried out. The surface morphology is carried out for structural analysis of printed samples. The sensor data is acquired and processed using an 8-bit ATmega-2560 micro­controller and wirelessly transmitted to a PC for post-processing, storage and analysis. For real-time data presentation of dis­tributed pressure points, a GUI has been developed to display the values ob­tained from the large area sensor. The detection of four sit­ting pos­tures; forward leaning, backward leaning, left leaning and right leaning along with a normal sitting posture is attained. An analysis for stretchable printed tracks has been conducted to investigate the changes in electrical resistance using elon­ga­tion tests, surface morphology and EDS. The optimal curing time and tem­per­ature were investigated to manufacture stretchable conductive tracks. In summary, the contributions in this thesis provides an effective approach regarding pressure distribution measurement and recognizing irregular sitting postures for wheelchair users.

Thesis (MTech( Electrical Engineering)) -- Cape Peninsula University of Technology, 2012
Due to the complex design of existing electric mobility vehicles in South Africa and their imported parts, make them unaffordable to the majority of disabled people in South Africa. The traditional electric units are also not practical for use in rural areas due to the heavy, bulky design. The scope of this study was to investigate various designs using existing wheelchair frame designs, low cost three phase hub motors and various electronic techniques to achieve the desired functionality. An attempt was be made to remove inefficient and expensive DC brush motors and the gear boxes associated with the traditional design of wheelchairs, while still allowing the unit to fold like the traditional manual chair design. One of the aims for this electric wheelchair was to utilise existing large radius wheels, typical of manual wheelchairs and a modified traditional frame design, providing the clearance often necessary to overcome rough terrain whilst enabling the chair to be used as a manual wheelchair should the battery fail. One of the primary aims of the project was to develop a method for an electric assist feature built into the modified electric wheelchair, whereby the force applied to the manual pushrims on the wheels would be measured and the electric component would proportionally assist the user. This option suits the users who are weak but not physically disabled. One of the many focal points here would be on HIV/AIDS patients, which is prevalent in South Africa, who may require a wheelchair when debilitated with this disease. The electric assist portion of the design would act similarly to a wireless self-powered torque sensor, allowing for an array of applications besides the electric assist portion of this project. A recent survey by National Government indicated that over 85% of wheelchair users only generated an income of between R0 – R500 per month. Low state disability grants and wage figures for disabled and HIV/AIDS patients mean that electric mobility vehicles have become a luxury rather than an essential commodity in South Africa. The need for cheap electric wheelchairs that could cope with the rural terrain and could be fitted onto existing manual wheelchairs offering the full manual operation should the batteries go flat, was clearly apparent. The cost of an electric wheelchair ranges from R18 000 with more advanced models escalating in price to well over R150 000. These prices were typically the result of the complexity of the unit and local wheelchair manufacturers having to import 80% of their parts from abroad. The largest local manufacturer is CE Mobility which is the dominant mobility vehicle supplier in Southern Africa and has the only SABS approved units for sale. Our complete redesigned wheelchair including the manual frame supplied by an existing supplier would only cost R9 000. A prototype demonstrated that is was possible to build a wheelchair that meets all these criteria. A cost effective unit could provide a solution to assist and enable economically challenged and disabled people in rural areas of Southern Africa.

Abstract:
Electric wheelchair users depend on a reliable power system in order to regain mobility in their daily lives. If a wheelchair’s battery power depletes without the user being aware, the individual may become stranded, further limiting their freedom of mobility and potentially placing the user in a harmful situation. This research seeks to develop a State-of-Charge (SOC) estimator for the batteries of an electric wheelchair. A second-order equivalent circuit battery model is developed and parameterized for a wheelchair’s lead-acid battery pack. To simplify the SOC estimation, this algorithm models a vehicle’s fuel gauge. A coulomb accumulator is incorporated to estimate energy usage in the non-linear region of the OCV-SOC curve, while a Kalman filter is used to estimate SOC in the linear region of the curve. The estimator is verified using experimentally collected data on-board a robotic wheelchair. The implementation of these algorithms with powered wheelchairs can significantly improve the estimation of wheelchair battery power and can ultimately be coupled with warning systems to alert users of depleting battery life, as well as enable low-power modes to increase wheelchair user safety.

Abstract:
This paper presents the design and implementation of a low-cost and reliable wireless motion control system for conventional electric wheelchairs. The presented work aims to enhance the mobility of handicapped and elderly wheelchair users by utilizing a mobile application to control the motion of their unattained wheelchairs. The designed system takes into consideration cost, weight, a range of operation, ease of use, and implementation. The conventional electric wheelchair is equipped with a motorized front wheel steering mechanism. In addition, it is equipped with a Wi-Fi module to support remote motion control via a specially designed Android mobile application called “Android Application For NavigAtioN”; AAFNAN for short. Experimental testing of the prototype showed successful remote motion control and ease of use.

Abstract:
Arthrogryposis is a congenital disorder characterized by extreme joint stiffness that inhibits strength and flexibility in upper and lower extremities. Cases vary in severity, but this research focuses on those in which patients require a wheelchair for mobility. Currently, two conventional designs exist: mechanical and electric wheelchairs. For most arthrogryposis patients, existing mechanical wheelchairs are insufficient for independent propulsion as their joints are severely impaired, prohibiting them from reaching the outer handrails on the wheels and expending enough force to propel and steer. Existing devices that improve the mechanical advantage of wheelchairs are insufficient for the needs of these patients who have very limited and specific ranges of motions, which are not compatible with the required force inputs. Though electric wheelchairs allow independent mobility, they are expensive to maintain and not easily portable, limiting their use by socioeconomically disadvantaged patients. Arthrogryposis patients require a lightweight, portable and durable mechanical wheelchair that takes advantage of the user’s specific strengths, and is easily maneuvered in all directions without assistance. A design is presented for a socioeconomically disadvantaged teenage client with arthrogryposis. After taking data regarding the ranges of motion and strength of the client, a new propulsion system was designed and retrofitted to a conventional wheelchair. Prototye I has been tested and a second-generation design which fits the needs of a wider audience suffering from arthrogryposis is presented.

Abstract:
In the recent years, the focus of ever-progressing scientific and technological advancements is continuously drifting towards the rehabilitation engineering. The development in the field of “mobility aid” has led to research, which has transformed conventional manual attendant-style wheelchairs to electric-powered wheelchairs with improved control through joysticks, sensors and micro-controllers. Consumers with limited mobility (pain in legs, permanent injury etc.) and elderly users, who cannot independently operate a powered wheelchair due to their hands impairment, have to rely upon third-party assistance during transfers to secure their wheelchair. Most ‘Mobility Assistance Equipment’ manufacturers for the orthopaedically handicapped individuals have not been able to adequately address such problems. With mobility being a key factor in all aspects of human life, this project proposes a design to allow hands impaired people, who cannot walk to orient themselves in, and navigate through, complex environments with the help of foot controlled wheel chair. This paper presents design and development of a battery-powered wheelchair that will be operated by foot controls, based upon the need assessments of such consumers. The Electronic System is a basic speed control circuit designed and provides for four motion configurations — reverse, stop, slow, and fast.

Abstract:
Along with the assisted wheelchair, a self-propelled wheelchair is also used as an assisted wheelchair by a caregiver; however, the problem with wheelchairs is that the vibration during driving causes motion sickness, discomfort, and annoyance for users. The tire pressure of the wheelchair is considered an influencing factor affecting the ride quality of the wheelchair; however, the extent of the effects of tire pressure on the wheelchair remains unknown. Therefore, this study aimed to evaluate the factors influencing the tire pressure changes of the self-propelled wheelchair on the vibration using the tire pressure indicator. Furthermore, this experiment aimed to improve data reliability by manufacturing a device that pushes out a self-propelled wheelchair using an electric wheelchair to run the self-propelled wheelchair at a constant speed. A dummy heavy object was placed on the seat of the self-propelled wheelchair of the vibration measuring device manufactured in this experiment, and a triaxial accelerometer was mounted on it. Moreover, an electric wheelchair is used to drive the uneven road surface at a constant speed at regular intervals. The tire pressure display manufactured in this study was attached to both sides of the rear wheel of the self-propelled wheelchair, and a dummy weight of 50 kg was placed on the seat. Then, acceleration in the vertical direction is measured by a three-axis accelerometer mounted on a heavy object. In this study, the effects of tire pressure on ride quality were considered by looking at the correlation between ride quality by sensory evaluation and vibration analysis.
