Abstract

A redundant planar three-dof cable-driven parallel robot is proposed and analysis of its cable-configuration is discussed in this paper. Loop cables and constant force springs unlimitedly rotate the endless-pulley which is embedded inside the moving part. The angle of the hand is redundantly given by the sum of the angles of the moving part frame and the endless-pulley. Three-dof hand is controlled by four-dof mechanism using five-cables. This means that the proposed CDPR is a novel cable-driven parallel robot which simultaneously has the kinematic and actuation redundancies. Tactical design and control for the cable-configurations are proposed as the robot satisfies the wrench-closure condition.
