Abstract:
1. A system for controlling motion interference avoidance for a robot movable along a rail comprising: a robot movable along a rail parallel to a longitudinal axis of the rail; a controller in communication with and controlling movement of said robot along the rail in one direction and an opposite direction; and a sequence of instructions executed by said controller to control the movement of said robot along the rail, wherein said sequence of instructions includes a dynamic space check control method that automatically creates a dynamic space for said robot based upon a current position of said robot along the rail, a command position along the rail to which said robot is to be moved and the one direction, said dynamic space including a high boundary, said dynamic space check control method moving said high boundary with movement of said robot in the one direction of movement to maintain said high boundary at a distance from said current position of said robot equal to said command position plus a predetermined offset distance in the one direction and said dynamic space check control method moving said high boundary with movement of said robot in the opposite direction of movement to maintain said high boundary at a distance from said current position of said robot equal to said predetermined offset distance in the one direction.
