Abstract
A direct drive robot based upon a closed loop parallel link arm with a hand mechanism mounted at the outer end thereof has a prime mover for driving the hand mechanism positioned such that mass and position parameters of a specific equation are satisfied by the parallel link arm, whereby interfering forces which would otherwise act between first and second prime movers driving the parallel link arm are eliminated.
