ABSTRACT:
Robotic hand includes retractable paddles for supporting an article and a vertically-movable top paddle for engaging an upper surface of the article. The top paddle is mounted on an upper free end of a band of sheet-like material, which may be extended above the top surface of a housing of the robotic hand. Inflatable bladders in the retractable paddles have a relatively high coefficient of friction, and the top surface of the paddles has relatively low coefficient of friction. A force sensor may be provided in the lower surface of the top paddles.
