ABSTRACT:
A three-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 transversely from the longitudinal axis of the first support. A second carriage is longitudinally movably mounted on the second support and has a third support selectively vertically movably mounted thereon. A dual cable driver traversing pulley is rotated by a reversible drive motor. First and second cable members are wrapped around the traversing pulley in opposite directions. The cable members are operatively connected to the upper and lower ends of the third support by a pulley arrangement. Traverse, horizontal and vertical brakes are provided to control the movement of the carriages and the third support.
