... servo- motors being offered today. Gearheads have often been selected for driving long trains of mechanisms in machines that perform such tasks as feeding wire, wood, or metal for further processing. ... the motor is applied directly to the load without any cou- plings, bearings, or other conversion mechanisms. The only alignments required are for the air gaps, which typically are from 0.0...

... actuators incorporated into a linkage that is classified as “P4R” in the discipline of kinemat- ics of mechanisms because it includes one prismatic (P) joint and four revolute (R) joints. The improved ... coordination of actuator motions neces- sary to obtain specified end-effector motions in the older mechanisms is a complex task, it is a relatively simple task in the improved mechanism....
