Interface into the robot controller
Positioners, sometimes called manipulators, tend to be servo controlled and are driven from the robot controller and programmed from the robot teach pendant. The movement of the positioner is integrated and programmed together with the robot, which means that the robot can move to the joint, whilst the positioner is bringing the joint into position. Alternatively if the assembly has an orbital weld (e.g. an exhaust system), the positioner can rotate the assembly whilst the robot remains stationary or moves along with the joint if the orbital weld is eccentric.
