New Linear Actuators for Asea Robot

Here you see the New Asea robot with its linear actuators.  The are two of them - one for the shoulder and one for the elbow motion.   The design has been changed from wire to chain actuation, which is far easier to build, works more smoothly and has more power.   Thus the design has evolved from its original screw thread, to wire and now to chain.   The original design in the prototype used a ball screw.
