ABSTRACT:
A robot arm includes a drive assembly and an articulated arm assembly pivotally connected to the drive assembly. The articulated arm includes a pivoting base link system, a wrist link system, and a first elbow link system rotatably connected to the base link system by a pair of upper arms and connected to the wrist link system by a pair of forearms, a second elbow link system rotatably connected to the base link system by another at least one upper arm and connected to the wrist link system by another at least one forearm, wherein the drive assembly is connected to at least one of the upper arms and the base link system to provide three degrees of freedom by driving the at least one of the upper arms and pivoting the pivoting base link system to position the wrist link system at a given location with a predetermined skew relative to an axis of translation.
