1. A telescopic pick and place robotic apparatus, comprising:

  • a base;

    a slider plate having first and second major faces;

    coupling means for coupling said slider plate to said base and for allowing said slider plate to telescopically extend and retract relative to said base along an axis, said axis being substantially parallel to said first and second major faces;

    gripper means, mounted on said slider plate, for selectively grasping and translating an object along said axis onto and off of said first major face of said slider plate, including,a first rack and pinion gear pair, said first rack gear coupled to said base and said first pinion gear coupled to said slider plate,a first pinch roller coupled to said slider plate by a first spring-loaded arm and rotatably driven by said first pinion gear,a second rack and pinion gear pair, said second rack gear coupled to said base and said second pinion gear coupled to said slider plate, anda second pinch roller coupled to said slider plate by a second spring-loaded arm and rotatably driven by said second pinion gear,wherein said first and second pinch rollers are rotated respectively by said first rack and pinion gear pair and said second rack and pinion gear pair when said slider plate is translated relative to said base along said axis; and

    translating means for translating said slider plate along said axis.
