ABSTRACT:
A two-axis Cartesian robot is described comprising a first horizontally disposed support having a first carriage selectively movably mounted thereon. A second support is operatively secured to the first carriage and extends perpendicularly from the longitudinal axis of the first support. A second carriage is vertically movably mounted on said second support. A belt pulley is rotated by a reversible drive motor. A drive belt is driven by the drive motor and operatively connected to the upper and lower ends of the second support by a pulley arrangement. Horizontal and vertical brakes are provided to control the horizontal movement of the first carriage and the vertical movement of the second carriage. A workpiece gripper or handling member is mounted on the second carriage for movement therewith.
