Advance of the new MA 23 force reflecting manipulator system

This new bilateral servo manipulator system is under development since 1974, in close cooperation between different french organizations with the leadership of the Commissariat a l'Energie Atomique. This Group is facing in the same Technology different applications covering nuclear remote manipulation, undersea remote work, second generation industrial robots and manipulators for handicaped persons. Brief description of the different arms ranging from 5kg to 20kg mass capacity are given with corresponding tested performances. They all use original electric DC actuators with extremely low friction and zero backlash, with only cables and tapes. System works in different modes: the direct master slave force reflecting mode, an advanced tape recording programmer, minicomputer control, and the combined modes. Work is concentrated on full dynamic control and force control by minicomputer
