Realizing an ideal impedance control system in lower extremity rehabilitation systems is challenged by mechanical impedance of robot hardware. Although some studies in the field of control systems have been helpful in reducing the mechanical impedance of actuators, they have not been able to remove the inertia of robot hardware. This paper introduces an alternative design in which mechanical links...
This paper describes finite state machine (FSM) to model the operation of novel untethered scratch drive micro-robot. Micro-robot consists of three scratch drive actuators (SDA) and two steering arms with dimension of 365 m times 78 m fabricated monolithically by commercially available PolyMUMPs process and deposited with dielectric layer in the post process. The micro-robot brain is programmed by...

Shape memory alloy (SMA) composites offer a great potential as actuators because of its excellent power to weight ratio, smooth motion and silent actuation. However, SMA actuated robotic manipulator systems have severe hysteresis, system nonlinearities, model and parametric uncertainties those are often responsible for position inaccuracy in a regulation or tracking system. A simple and upstanding...

Robotic marionettes are those mechatronic system in which strings that control motion of a puppet are driven by a puppeteer platform including motor-pulley modules. Systematic control of robotic marionettes is now still a tough problem, which several research groups have been attempting to solve. In this paper, we present dynamic models of the robotic marionette developed from Lagrange equation. Feed-forward...
In this paper we discuss an energy-based control method for a class of under-actuated mechanical systems. The control law is proposed and the convergence analysis is carried out based on Lyapunov stability theory. The conditions on the parameters in the control law such that the total energy of the controlled objects converge to the potential energy of their desired position are given. Under such...
An electromagnetic DC actuator with multi degrees of freedom intended for use in the joints of robots was developed. The principle of the synchronous motor is extensively applied in the construction of an electromagnetic DC actuator with multi degrees of freedom. Experimental results by the developed actuator show the characteristics of low torque and slow response to be used robots.
The multimodal teleoperation interface has to improve the human control over the microrobots and the overall nanohandling station by immersing the user into the microworld in which the nanohandling procedures take place. The user will receive more information about the state of the nanohandling process and in a more convenient way than by other existing teleoperation interfaces: Force information...
This paper presents a new variable focal liquid lens system that uses a SMA (shape memory alloy) actuator. Making a conventional variable focal liquid lens system small and light is difficult, due to the requirement of a large and heavy actuator, such as a pump or an electric motor, to distribute the liquid in the liquid lens. Plus, focal control is also difficult, due to a nonlinear focal variation...
In this paper we describe some experiments that can serve to support an integrated classroom - workstation - laboratory control systems engineering curriculum. The experiments were selected to be representative of control system problems one can expect to encounter in Aeronautics and Astronautics, Electrical Engineering and Mechanical Engineeing and thus provide a cross - departmental setting for...
