Abstract
Single or multiple flexible robotic manipulator trunks can be made from individually activated, three degree-of-freedom, flexible robotic links. Three dimensional positioning and orientation of the distal end of each link is achieved exclusively by elastic deformation of the flexible link assembly without revolute or prismatic joints. The activating bending and torsional moments required for such a positioning are generated by the antagonistic action of a plurality of prestressed, inflatable, laterally bendable and axially extensible tubular actuators with the anisotropic, circumferentially reinforced walls. The positioning motion, working forces and manipulator arm stiffness are all controlled by asynchronously modulated pulse streams which regulate the distribution of energy from a common source of fluid under constant pressure.
