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 with respect to the longitudinal axis of the first support. A belt pulley is rotated by a reversible drive motor and is operatively connected to the upper and lower ends of the second support by a pulley arrangement. A horizontal brake is provided to control the movement of the carriage with respect to the first support. A vertical brake is provided to control the movement of the second support with respect to the carriage. A workpiece handling member is mounted on the lower end of the second support for manipulating the workpiece being handled.
