Abstract
A system and method for controlling avoiding collisions in a workcell containing multiple robots is provided. The system includes a sequence of instructions residing on a controller for execution thereon to perform an interference check automatic zone method. The interference check automatic zone method includes the steps of: determining a first portion of a common space that is occupied during a movement of a first robot along a first programmed path; determining a second portion of the common space that is occupied during a movement of a second robot along a second programmed path; comparing the first portion and the second portion to determine if an overlap exists therebetween; and moving the first robot and the second robot in response to whether or not the overlap exists.
