Abstract
A sufficient condition for the stability of robot manipulators in constrained maneuvers is derived. Attention is focused on the class of direct drive robots whose rigid links dominate the robot´s dynamic behavior; compared to the robot, the environment is assumed to be infinitely rigid. The stability of the manipulator-environment system is investigated, and a bound for stable manipulation is determined. This bound is verified via simulation and experiment on the Minnesota direct drive robot
