ABSTRACT:
A robot arm in which a hand or end effector placed at the end of, and pivotally joined to first and second pivotally coupled arms is caused to experience linear, straight line motion in response to a single rotary actuator at the far end of the further most arm. A series of belts and pulleys of different sizes coordinate the motion of the two arms and the hand in order to produce straight line or radial motion in response to a single rotary actuator. The robot arm has particular application in semiconductor wafer handling systems in such capacity as transferring wafers between storage cassettes and test platforms and in this application is married to Z and .theta. motion drives.
