Symmetrical Pneumatic Muscle Actuated Gripper System with Two Mobile Jaws

Abstract:

The paper argues the possibility of utilising artificial muscles actuated with compressed air in the construction of industrial gripper systems. Their utilisation as motors comes as a response to the increasingly sophisticated requirements these have to satisfy, related to the developed force, structural rigidity, compliance and dexterity. The paper presents a variant of symmetrical gripper system with two mobile jaws actuated by a pneumatic muscle. The main requirements for this gripper are defined, the structure of the mechanism is presented and the transmission functions of forces and velocities are determined. Eventually the paper discusses the construction of the system and its functional limitations.
