Abstract
A direct drive robotic manipulator is provided which includes a plurality of segments that are rotatably coupled with respect to one another. A plurality of spindles connects the segments for relative rotation therebetween, and a plurality of direct drive assemblies is further coupled to the plurality of spindles. Each direct drive assembly encloses an end of a spindle and comprises a rotor assembly to which the spindle is attached for manipulating the spindle. A positional measurement apparatus may also be included at each direct drive assembly to ascertain an angular disposition of a segment relative to an adjoining segment.
