This is a B.A.S.E. Mack Corp. Pneumatic Robotic Arm Gripper which came out of a commercial estate and it is in good looking condition. It is the kind of robot that would be used for sampling materials that would be unsafe for humans to touch. It includes miniature high energy hydraulics, pneumatic cylinders, pistons, hydraulic actuators, solenoids, and many other components made by B.A.S.E. and Mack Corporation (Mackcorp.com). This kind of highly sophisticated robot is hard-to-find whether you want to use it for display, for components, and/or other creative purpose. It has a 1/2''x24''x24'' solid aluminum base, measures 24''x24''x28'' and weighs 78 pounds.
