摘要: 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.

摘要: An apparatus and method are provided for attenuating vibration when driving an object. The apparatus includes a driving device for generating a driving force to drive the object and an attenuation actuator mounted in reciprocal relationship with the driving device for generating an attenuation force substantially concurrently with the generation of the driving force. The attenuation force is generated so as to oppose and at least partially cancel a reaction force exerted by the object in response to the driving force.
