<p>A tele-manipulator comprises a primary piston moving along guide bars, a chassis carrying a secondary piston. The secondary piston moves rods which adjust the angle of inclination of a third piston pivoted on the same chassis. The third piston extends or retracts so that the complementary action of all three pistons achieves universal positioning of a fixture or grab on the third piston.</p> |
