Abstract:
In this paper, a novel monolithic structural design of a piezoelectric (PZT) inchworm motor utilizing three force amplification mode (FAM) mechanisms is presented as an approach to overcome the design challenges of common PZT inchworm motors. A mechanical system model based on Simulink software was developed for a proposed inchworm motor design. The dynamic response of the motor was simulated at the moment of releasing the pre-stressed mechanism. The results showed a backlash response due to the mass acceleration of the mechanisms.

Abstract:
The inchworm-driven actuator is an important type of piezo-driven actuators, which has high loading capacity, large motion range and high motion accuracy but involves complex structures, control and motion processes. In this paper, an inchworm type piezo-driven rotary actuator was introduced. Static and modal analyses of key units of the rotary actuator such as the clamping unit and the driving unit were carried out by finite element simulations to ensure that key units of the rotary actuator have enough strength and good dynamic characteristics. These simulation results will be helpful to improve structure design of the inchworm actuator.

Abstract:
SUMMARYTo obtain better performance on unstructured environments, such as in agriculture, forestry, and high-altitude operations, more and more researchers and engineers incline to study classes of biologically inspired robots. Since the natural inchworm can move well in various types of terrain, inchworm-like robots can exhibit excellent mobility. This paper describes a novel inchworm-type robot with simple structure developed for the application for climbing on trees or poles with a certain range of diameters. Modularization is adopted in the robot configuration. The robot is a serial mechanism connected by four joint modules and two grippers located at the front and rear end, respectively. Each joint is driven by servos, and each gripper is controlled by a linear motor. The simplified mechanism model is established, and then is used for its kinematic analysis based on screw theory. The dynamics of the robot are also analyzed by using Lagrange equations. The simulation of the robot gait imitating the locomotion of real inchworm is finally presented.

Abstract:
Modern society is fueled by very comprehensive grids of gas and liquid supply pipelines. The frequent inspection and maintenance of such pipeline grids is not a trivial task. It has been demonstrated that such task is best performed by using in-pipe robots. In this paper, a novel inchworm robot design and its optimized motion planning are presented. The proposed design uses a helical drive for both gripping and locomotion of the robot. The extension and retraction between inchworm segments are facilitated by conic springs as they can store strain energy. The proposed inchworm robot can also be made very compact without sacrificing stroke length as conic springs can be easily designed with telescopic feature. To generate inchworm motion, a sinusoidal velocity pattern is planned for each segment. The frequency of the velocity pattern is optimized using a genetic algorithm (GA). The optimization result from the GA method has been validated using a traditional gradient based method.

Abstract:
An unconventional inchworm actuator for precision positioning based on piezoelectric (PZT) actuation and electrorheological fluids (ERFs) control technology is presented. The actuator consists of actuation unit (PZT stack pump), fluid control unit (ERFs valve), and execution unit (hydraulic actuator). In view of smaller deformation of PZT stack, a new structure is designed for actuation unit, which integrates the advantages of two modes (namely, diaphragm type and piston type) of the volume changing of pump chamber. In order to improve the static shear yield strength of ERFs, a composite ERFs valve is designed, which adopts the series-parallel plate compound structure. The prototype of the inchworm actuator has been designed and manufactured in the lab. Systematic test results indicate that the displacement resolution of the unconventional inchworm actuator reaches 0.038 μm, and the maximum driving force and velocity are 42 N, 14.8 mm/s, respectively. The optimal working frequency for the maximum driving velocity is 120 Hz. The complete research and development processes further confirm the feasibility of developing a new type of inchworm actuator with high performance based on PZT actuation and ERFs control technology, which provides a reference for the future development of a new type of actuator.

Abstract:
SUMMARYThe flexible motion of the inchworm makes the locomotion mechanism as the prominent one than other limbless animals. Recently, the application of engineering greatly assists the inchworm locomotion to be applicable in the robotic mechanism. Due to the outstanding robustness, sliding mode control (SMC) has been validated as a robust control strategy for diverse types of systems. Even though the SMC techniques have made numerous achievements in several fields, some systems cannot be comfortably accepted as the general SMC approaches. Accordingly, this paper develops the Grey Wolf-Second order sliding mode control (GW-SoSMC) to control the manipulator of the inchworm robot. The GW-SoSMC reduces the chattering phenomenon of SMC and improves the controlling ability of SoSMC by weightage function. Subsequently, it compares the performance of the proposed method with several conventional techniques like Grey Wolf-SMC (GW-SMC), FireFly-SoSMC (FF-SoSMC), Artificial Bee Colony-SoSMC (ABC-SoSMC), Group Searching-SoSMC (GS-SoSMC), and Genetic Algorithm-SoSMC (GA-SoSMC). It portrays the valuable comparative analysis by measuring the accomplished joint angles, error, and response of the controller. Thus the proposed method discovers the supervisory controller for the inchworm robot that is immensely better than conventional controllers mentioned earlier.

Abstract:
This paper reports upon the design and evaluation of an inchworm drive based on frictional anisotropy for an Active Scope Camera (ASC), which is a snake-like rescue robot used in disaster-affected areas. The conventional ASC is mounted on a ciliary vibration drive and can search under rubble. It has been found, however, that there are some situations in which the vibration drive performs weakly, such as on soft or rough road surfaces. In this paper, the authors propose an inchworm drive with an ASC. The inchworm drive developed in this research shows a running performance that resolves some of the weak points of the vibration drive. The authors focus in particular on the evaluation of driving experiments that were conducted on a variety of surfaces that might be encountered while searching inside a collapsed building or under rubble.

Includes bibliographical references (p. 67).
A continuing goal in the automobile seat drive industry is to design lighter, smaller, more economical seat drives that offer excellent long-term performance. The way to achieve this goal is to minimize the number of parts and part complexity while meeting all safety and functional requirements. Current seat drives which use motorized lead screws are large and heavy. An alternative solution that the industry is exploring to replace the lead screw seat drive is a simple linear actuator. The goal of this project is to design an inchworm motion linear actuator that may be used as part of the seat drive system to provide fore-aft motion. The resulting final design is a simple system that consists of two modules, an actuation module and a clamping module. The actuation module is a simple motor-wobble plate assembly and the clamping module consists of spring-loaded jamming plates. The final prototype succeeded in inching the shaft forward in one direction, but failed at shifting directions. This failure can be remedied in future work by the introduction of an actuation guide plate as well as the more accurate and detailed machining of components.

Abstract:
The focus of this research was to create a linear motor that could easily be packaged and still perform the same task of the current DC motor linear device. An incremental linear motor design was decided upon, for its flexibility in which the motor can be designed. To replace the current motor it was necessary to develop a high force, high speed incremental linear motor. To accomplish this task, piezoelectric actuators were utilized to drive the motor due their fast response times and high force capabilities. The desired overall objectives of the research is to create an incremental linear motor with the capability of moving loads up to one hundred pounds and produce a velocity well over one inch per second. To aid the design process a lumped parameter model was created to simulate the motor's performance for any design parameter. Discrepancies occurred between the model and the actual motor performance for loads above 9.1 kilograms (20 pounds). The resulting model, however, was able to produce a good approximation of the motor's performance for the unloaded and lightly loaded cases. The phase one design was limited by time constraints so a relatively low risk design was produced. The resulting incremental linear motor produced a velocity of 4.9 mm/sec (0.2 in/sec) at a drive frequency of 50 Hz. The velocity of the motor was limited by the drive frequency that the amplifiers could produce. The motor was found to produce a respectable stall load of 17 kilograms (38 pounds). The stall load of the phase one design was severely limited by clearance losses. An analysis of the motor's performance was conducted, possible improvements and future work recommendations for a phase two design are presented.

Abstract:
In this thesis, a snake like robot is implemented for search and rescue applications. The snake is intentionally selected as a reference for their ability to move on various environments, but due to the mechanical limitations the implemented snake-like robot design could not be close to the biological counterparts. Although the implemented snake like robot is not a replica of biological snakes
it captured key aspects of snakes such as flexibility, redundancy and high adaptation. To depart from the mechanical limitations
a model of the implemented robot is designed in MATLAB - SIMMECHANICS including a model for the environment. The implemented model is based on the implemented snake like robot but possessed extra features. The model is controlled to perform common snake gaits for navigation. Obstacle avoidance, object (debri or victim) v reaching and object dragging behaviors are acquired for the implemented gaits. Object dragging is accomplished by pushing an object by head or the body of the robot without lifting. For effective navigation, appropriate snake gaits are conducted by the model. All control operations such as obstacle avoidance for each gait and gait selection
a network of self tunable FACL (fuzzy actor critic) fuzzy controllers is used. Although the adapted snake gaits result in the movements which have properties that are not a replica of the real snake gaits, self tunable controllers offered best available combination of gaits for all situations. Finally, truncated version of the controller network, where the implemented mechanical robot&

Abstract:
Ce travail de thèse porte sur le développement et la modélisation d'actionneurs piézo-électriques à densité d'efforts élevés et pouvant produire des mouvements de rotation et de translation. Une étude comparative des différentes structures d'actionneurs a mis en évidence le potentiel électromécanique intéressant de l'actionneur cylindrique à rotation de mode. Une étude approfondie de ce dernier a été entreprise et a permis de le modéliser analytiquement par des schémas de Mason ou par des méthodes variationnelles. Cette dernière approche a permis également de retrouver les paramètres électromécaniques du moteur à partir de simulations par éléments finis (ANSYS). Des prototypes d'actionneurs diphasés et monophasés ont été réalisés et ont permis de valider les modèles développés. Leurs alimentations résonantes associées ont également été étudiées. L'objectif suivant a été d'intégrer au sein de la structure du moteur à rotation de mode un dispositif permettant d'assurer le degré de liberté supplémentaire en translation. Le choix s'est porté ici sur un fonctionnement original de type inchworm permettant de découpler cette fonction du mouvement rotatif résonant. Un prototype a permis de valider le principe de fonctionnement en translation de l'actionneur. Une alimentation MLI à commutation douce a été réalisée afin de pouvoir générer les formes d'ondes exigeant une large plage de fréquences (du continu à plusieurs dizaines de kHz).

Along with the mutuality of precision machinery technology, the demand on precision positioning stage has increased. The use of servomotor with ball-screw for positioner can not fulfill the nanometer precision requirement. Hence, many researches focusing on the positioner driven by piezoelectric actuator were performed. Due to its limitation of small stroke, the application of this kind precision stage was not quite widespread. The purpose of this study is tried to develop a precision stage that has multiple degree of freedom and longer stroke with nanometer precision. In this study, an inchworm type positioner was developed. The functional requirements were discussed firstly. A conceptual design was followed according to these functional requirements. Mathematic model of the positioner was constructed, followed by genetic algorithm for optimum design. Finite element analysis together with experiment was conducted to verify the design.

As the application aspect of Scanning Probe Microscopy is getting wider, the key actuator component satisfies various demands in the application, to increase the positioning precision and actuating stability or to adapt to the testing environment. The purpose of this thesis is to develop a two-dimensional piezoelectric actuator suitable for Scanning Probe Microscopy, the actuator is used for driving the scanning probe or the measured component, providing large scale scanning as well as fast positioning of the scanning probe. The inchworm motion is used as the actuating principle, in order to avoid actuating instability caused by multi axial fold structure and to enhance the compactness of the actuator, the two-dimensional actuators are combined on the same plane, the electromagnetically absorbing way is adopted to replace the traditional clamp mechanism, and simplification of the structure makes it easier to produce a coplanar motion. By utilizing a fixed guiding plane and a movable guiding plane, the two-dimensional actuating function is combined, and it offers an accurate and a steady displacement guiding of the actuator. Actuator of each dimension consists of two electromagnetic suckers and a piezotube, the absorbing force of the electromagnetic sucker can be altered by controlling the magnitude and polarity of electric current, and thus allows the deformation accumulation of the actuator which results in long stroke and reciprocating displacement. Magnetic field combination of permanent magnet and electromagnetic coil produce the overall electromagnetic sucker magnetic field which is cooperated with proper magnetic circuit design, the permanent magnet offers the magnetic absorbing strength to stabilize the position while power disconnected, moreover, the electromagnetic coil is used for releasing the sucker magnetism’s absorbing force while actuating. The absorbing performance of magnetic sucker and the actuating performance of actuator were carried out into deep discussion by experimental testing and analyzing of various types of simulation, and thus figured out various kinds of factors which affect its efficiency.

In this thesis, characteristic studies on the driving mechanism of STM (Scanning tunneling microscope) are made. The mechanism consists of an impact drive mechanism (IDM), an inchworm actuator, and a piezoelectric actuator for the measuring tip. In rough position control of the driving mechanism, the IDM is actuated by piezoelectric impact force for obtaining a relatively large operational range. In fine position control, the inchworm actuator is used for obtaining high-resolution step motion of the measuring tip. Fundamental experiments and position control are carried out for the driving mechanism, and the tunnel current is measured for the application of STM. The main content of the thesis covers the following research works: the configuration of the experimental setups and the examinations the motion characteristics of the driving mechanism. On the studies of the IDM for rough position control, the motion characteristics are examined based on different parameters such as the amplitude of the applied voltage, the acceleration, the pulse width, and the preset force. The experimental results show that the IDM was successfully positioned with a rough positioning accuracy of 30 nm. On the studies of the inchworm actuator for fine position control, the average step resolution having 2.5 nm/V is obtained by the driving signals of step and ramp waveforms. As for the position control of the measuring tip, a PID controller was configured and with a precise accuracy of 15 nm. Finally, the controllable driving mechanism is applied to the STM for measuring tunneling current. The characteristic relation between the tunneling current and the gap distance is obtained. According to these experimental results, the effectiveness of the driving mechanism for the application of STM has been demonstrated. Having the advantages of high-precision positioning ability, low cost, and simple controller, it is expected that the driving mechanism studied in the thesis can be applied to the precision positioning fields. Especially, due to its simple structure, it is easy to configure different measuring devices based on the driving mechanism for the application in semiconductor or biotechnologies, etc.

Abstract:
This chapter discusses various mechanical designs for STM and AFM. The central piece of the mechanical design of STM and AFM is the course positioner. Therefore, various types of course positioners are also discussed. The louse and the pocket-size STM are discussed first. It is of significant historical importance but no longer popular today. The single-tube STM has a very simple mechanical structure, and still the basis of the most popular commercial STM and AFM. The Besocke-type or the beetles is very popular among builders of special-purpose STM due its immunity to temperature variation and vibration. For STM requiring superb stability, the walker and the kangaroo are the preferred design. The commercial nanostepper, the Inchworm, is described. It has been successfully used by many designers of special-purpose STM.

Abstract:
Stepping piezoelectric actuators have achieved significant improvements to satisfy the urgent demands on precision positioning with the capability of long working stroke, high accuracy and micro/nano-scale resolution, coupled with the merits of fast response and high stiffness. Among them, inchworm type, friction-inertia type, and parasitic type are three main types of stepping piezoelectric actuators. This chapter is aimed to introduce the basic definition and typical features of the parasitic motion principle (PMP), followed by summarizing the recent developments and achievements of PMP piezoelectric actuators. The emphasis of this chapter includes three key points, the structural optimization, output characteristic analysis and performance enhancement. Finally, the current existing issues and some potential research topics in the future are discussed. It is expected that this chapter can assist relevant researchers to understand the basic principle and recent development of PMP piezoelectric actuators.
