Robot control apparatus

A robot control apparatus of a type adapted to control plural robots, comprising:

• a moving position setting unit for setting moving positions of a hand of a robot based on a coordinate system of the hand;
• a first coordinate transformation unit connected to said moving position setting unit for transforming an output from said setting unit into information in a predetermined general coordinate system;
• a selector connected to said first coordinate transformation unit for changing destinations of output information from said first coordinate transformation unit in dependence upon which of said plural robot is to be controlled;
• a second coordinate transformation unit connected to said selector and having a pluarality of transformation sections for transforming outputs of said general coordinate system into coordinate system information inherent to that one or ones of said plural robots to be presently controlled, the output from said first coordinate transformation unit being applied selectively to said transformation sections by said selector;
• and
• means connected to said second coordinate transformation unit for producing signals for driving said one or ones of said robots to be presently controlled, in response to output information from said second coordinate transformation unit.
