Actuator selection for over-actuated systems using the actuator effectiveness index
International Journal of Dynamics and Control, 2020This paper presents a new actuator selection methodology for over-actuated systems based on the actuator effectiveness index. In the proposed method, possible actuator candidates are quantitatively compared. The index is calculated for all candidates and is then used to select the appropriate actuator set based on their effectiveness.

A Novel Stick–Slip Piezoelectric Actuator Based on a Triangular Compliant Driving Mechanism
IEEE transactions on industrial electronics (1982. Print), 2019There is a growing demand for positioning actuators with a higher resolution, accuracy, speed, and driving force. Various piezoelectric actuators have been proposed to meet these requirements; however, they all have inherent limitations.

An XYθ mechanism actuated by one actuator
Mechanism and Machine Theory, 2004Abstract This paper presents a novel type of XYθ mechanism, in which three-degree-of-freedom motion in plane could be obtained with one actuator. The principle of the mechanism is described. One application of the novel mechanism is used in flexure hinge mechanism for micro-planar robot.

Study of micro-actuator with electrostatic actuating
SPIE Proceedings, 2006The micro-actuator with the torsion beam and the cantilever beam on silicon is designed and analyzed, which is actuated by electrostatic force. Based on the torsion dynamics theory, the technique and relative formula are presented for analyzing the actuating voltage and the switching time, on which the effect of the air squeeze film damping is already ...

MEMS actuator and relay with horizontal actuation
The Journal of the Acoustical Society of America, 2010A micro-electromechanical (MEMS) actuator and relay are implemented using a copper coil and a magnetic core. The magnetic core includes a base section that lies within the copper coil, and a cantilever section that lies outside of the copper coil. The presence of a magnetic field in the coil causes the cantilever section to move horizontally away from ...

Actuation of MEMS by Light: An Optical Actuator
Micro-Electro-Mechanical Systems (MEMS), 2001Abstract This paper presents experimental evidence that MEMS devices may be manipulated using beams of light. Light possesses momentum, and hence it imparts a force equal to 2W/c when perfectly reflected by a surface. Here W is the total power of the reflected light, and c is the speed of light.

Compliant actuation of parallel-type variable stiffness actuator based on antagonistic actuation [PDF]
Journal of Mechanical Science and Technology, 2010 For a service robot requiring physical human-robot interaction, stable contact motion and collision safety are very important. To accomplish these functions, we propose a novel design for a parallel-type variable stiffness actuator (PVSA). The stiffness and position of a joint can be controlled simultaneously using the PVSA based on an antagonistic ...
