Field Experiments with the OctArm Continuum Manipulator

Abstract

In contrast to traditional robotic manipulators composed of rigid links, a continuum manipulator is a long, continuously flexible extremity that grasps objects usingthe entire length of the trunk. OctArm, a three-section continuum manipulator composed of 9 McKibben actuators, was mounted on tracked mobile platform and teleoperated in a series of field and laboratory experiments. Results from these experiments show its ability to grasp objects of many shapes and sizes, retain a solid hold despite vibration or changes in acceleration, cradle fragile objects reliably, and operate in extreme environments. This robust featureset shows the usefulness and strong potential of these manipulators.
