Abstract
A master slave manipulator system includes a master arm having six or more axes of motion and an articulated slave arm having six or more axes of motion and being shaped in sharp contrast with the master arm. The master arm has an arm body with three axes perpendicular to each other and a wrist assembly connected to the arm body. The wrist assembly has a gripper disposed in a space of a size large enough for an operator to operate the gripper with his clutched hand in X, Y and Z directions and also has a pitch-axis, a yaw-axis and a roll-axis all disposed outside of the space. The pitch-axis, yaw-axis and roll-axis have output axes directed toward the gripper. The slave arm has an arm body with axes longitudinally stretchable or foldable into parallel positions, and a wrist assembly having three axes disposed in a space of predetermined dimensions in X, Y and Z directions. The output axes of the three axes of the slave arm wrist assembly are directed away from the mounting portions of these axes. The slave arm is so controlled as to follow movements of the master arm.
