The application of robotic hands in industry have thus far been mostly limited to simple two- or three-finger grippers.
A renowned German research institute had as a project goal to develop multi-finger hands where each finger could be controlled separately with the respective sensitive miniature microdrives. In order to simulate the basic functions of a hand, at least four fingers are necessary: three fingers so that cone structures can also be gripped, and an opposing thumb. The thus possible range of motion, however, must be precisely steered and controlled. Especially for sensitive jobs, quick feedback for the comparison of the target value and the actual value is essential for the correct functioning of the controls. The solution for positioning and control of the miniature microdrives was to use extremely precise ferrite rings upon which extremely short pole lengths were applied with the highest precision using Bogen technology.

 

Customer advantages:

Through high resolution, there are new possibilities for precision steering of robot hands
Very compact for the smallest of microdrives
