PR Series are multi-directional gantry type robotic systems which consist of cartesian X, Y and Z axes (can be used one or all of these axes), 6 axes robot can be connected externally. They have less metal construction than the GR Series and have 2-way access ability. Pillar Robots are new series of gantry type robots which are compact and flexible and they can move with high precision in 3 axes synchronously with the robot.
