Parallel kinematic mechanism and bearings and actuators thereof

An improved parallel kinematic mechanism to orient a platform has a higher range of motion for its volume due to the use of magnetically coupled ball joints at the orienting platform and the individual linear actuators operating those joints. The linear actuators may be printed circuit board (PCB) b...

Beschreibung
Zusammenfassung:	An improved parallel kinematic mechanism to orient a platform has a higher range of motion for its volume due to the use of magnetically coupled ball joints at the orienting platform and the individual linear actuators operating those joints. The linear actuators may be printed circuit board (PCB) based voice coil actuators, in a magnetic field which may be generated by permanent magnets configured as a modified Halbach array. The PCB based voice coil actuators may have a position sensitive device (PSD) embedded on the PCB to assist in determining location of the actuator with a high degree of accuracy. The payload of the orienting platform may be dynamically repositioned with improved accuracy and speed.
