Abstract: Abstract Cable-driven continuum manipulators are widely used in confined space applications, e.g. minimally invasive surgery. Different from conventional rigid manipulators, their end-effectors are positioned by deforming the flexible backbone. Existing workspace analysis of cable-driven continuum… read more here.

DOI: 10.1115/1.4046035
Abstract: The shape prediction of tendon-driven continuum manipulators is a challenging problem due to the effect of inner friction and external force. Many researchers use actuation displacement or actuation force as model input to predict the… read more here.
