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.

Full textit 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&

Magnetostrictive effect and inchworm principle act as the comerstones in realising the actuator. Giant Magnetostrictive Material (GMM) bas been used due to its unique features of high magnetomechanical coupling. It bas potentials to render high force and precise displacement with a small volume. A design and a model integrating the driving material, the electrical, the magnetic and the mechanical design bas been completed. A mini-actuator prototype bas been constructed. Experimental tests show on the one band that the actuator can perform fast linear movement with velocity up to 97. 2 um/s, on the other band, that it bas the potential to achieve a positioning resolution of 4 nanometers. A long stroke movement with nanometric positioning could be implemented

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.
