The problem of selecting joint space trajectories for redundant manipulators is considered. Solutions which allow secondary tasks to be performed by the arm simultaneously with end-effector motions may be selected in a number of ways. An algorithm to accomplish this, by means of conditions on a scalar function of the joint variables, is introduced and analyzed. Problems inherent in schemes involving constraints in configuration space are considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
