A new RObotic Muscle ACtuator (ROMAC) is based on a pneumatic, axially-contractable device, involving an articulating polylobe bladder with a flexible, non-elastic sheath construction. The actuator exhibits muscle-like characteristics; it is single-acting and compliant. An antagonistic pair of the actuators can be used to operate a double-acting system and permit a dynamic control of the compliance as an independent variable. The paper provides details on an experiment which demonstrated that myoelectric signals from operator's two biceps or a biceps-triceps pair can be used to provide teleoperated compliance and position control of a ROMAC-powered, double-acting robotic link. The teleoperation of compliance, by means of myoelectric signals to ROMAC actuators, provides a dynamic and intuitive control of joint stiffness by a human operator, and thus allows remotely controlled robots to undertake impulse-dominated tasks in unstructured environments.
