Designed for handling light loads at high speed, the basic structure is made up of two flexible bands that meet at one end to form a triangle. Intermediate stays are connected to the bands at regular intervals by articulated joints. This flexible design enables the gripper fingers to adapt to the shape of a work piece when pressure is applied laterally. The proportional pneumatic valve VPPM ensures that the pressure is correct.  Everything is connected to the robotic controller CMXR which controls the Tripod robotic handling unit.
