ABSTRACT:
A robot with a base, a first link connected to the base by a shoulder joint, and a second link connected to the first link by an elbow joint. A shoulder motor drives the shoulder joint, and an elbow motor drives the elbow joint. An upper elbow pulley is coupled to the first link. An end effector pulley coupled to the upper elbow pulley, and a dual-bladed end effector driven by the end effector pulley. The diameter of the upper elbow pulley and the diameter of the end effector pulley are related by a 1:2 ratio. Ferro-fluid seals are used to seal each joint. A static seal joins the seams of the links. Each arm link has a particle filter. The robot can communicate electrical signals through the revolute joints with a conductive slip-ring assembly. Alternately, the joint may have an inner cylinder and an outer cylinder, and a cable may be coiled between the cylinders.
