The lightweight design uses high rigidity ballscrews in conjunction with Kawasaki's hybrid link mechanisms (a parallel link on joint 2 and a serial link on joint 3). The hybrid link mechanism removes the need for heavy and bulky counterweights, and facilitates a compact footprint of 1.2 by 1.3 m. A wide motion range is another benefit of the hybrid link design, enabling up to 4.005 m horizontal reach and 4.416 m vertical reach.
Two 5 kW motors are deployed on each of the major axes (joints 1-3), while all M-Series robots are designed to withstand high reactionary torques to the wrist.
