Abstract

The box frame construction of a robot includes the X arm, the Y arm and the Z arm. The Z arm is movable up and down and is carried on the X arm. The end of the X arm is supported on the Y arm. The Z arm, X axis unit is driven in the Y direction along the Y axis. The X axis arm is formed as a one-piece casting which includes the X arm-Y axis joint 10, the sensor bracketry, cam follower mounting pads, stops, etc. The X arm-Y axis joint 10 is made sufficiently long in the Y axis direction such that the Y direction drive motor 12 can be located in line with the Z axis arm mass 13. The increased length of the X arm -Y axis joint 10 also provides an increase in the stiffness of the X axis and, consequently, an improvement in the accuracy and repeatability of the manipulator.
