PCT No. PCT/FR92/00633 Sec. 371 Date Dec. 9, 1993 Sec. 102(e) Date Dec. 9, 1993 PCT Filed Jul. 3, 1992 PCT Pub. No. WO93/01652 PCT Pub. Date Jan. 21, 1993.An electric jack of the type used in robotics having a rotation-translation movement transformation system, at least one electric motor connected to the movement transformation system, means for controlling the electric motor for driving the movement transformation system with acceleration and deceleration phases and energy recovery means for recovering electrical energy generated by the electric motor during deceleration phases. The movement transformation system has a rotation part and a translation part and is mechanically reversible such that, during deceleration phases, the translation part is capable of driving the rotation part with substantially identical efficiency as the rotation part drives the translation part during acceleration phases. During deceleration phases, the kinetic energy of the translation part causes the electric motor to generate energy which is recovered and stored in an energy recovery system utilizing a capacitor and a diode. |
