Abstract
A power assist apparatus includes an autonomously mobile base on which a manipulator for holding a load is mounted. The movement of the mobile base is controlled such that when the manipulator tip is within a prescribed operating region relative to the mobile base, the mobile base is maintained stationary, but when the manipulator tip moves outside the operating region, the mobile base is moved to decrease the distance between the mobile base and the manipulator tip. The power assist apparatus assists with the carrying of loads by amplifying an operational force applied to the manipulator.
