Design of a new type of spherical voice coil actuator
Sensors and Actuators A: Physical, 2013Abstract In this article, we describe the design of and an experiment with a new type of spherical voice coil actuator. The designed actuator has a large tilt angle of ±40°, high tilt torque, and a uniform and decoupled torque constant for each coil within a compact diameter of 100 mm.

Planar fabrication of a mesoscale voice coil actuator
2014 IEEE International Conference on Robotics and Automation (ICRA), 2014Mesoscale robots are devices with characteristic dimensions in the centimeter to millimeter scale, with feature sizes ranging from millimeters to micrometers. Due to the physics involved in scaling down conventional motors, such robots frequently require novel approaches to actuation. Actu- ation can have a very significant effect on robot performance,

Beam-stabilized optical switch using a voice-coil motor actuator
Journal of the Franklin Institute, 2011Abstract This paper presents the design, analysis, and implementation of a beam-stabilized optical switch using a voice-coil motor actuator. A closed-loop control system using a proportional-integral-derivative (PID) controller is developed to stabilize the beam at the desired angle to maximize the optical power detected by a photodiode.
