ABSTRACT
A novel 6 dof 8 cable-driven parallel robot (CDPR) is proposed. The proposed robot is redundantly driven by 8 cables. By the rotational mechanism inside the moving part (MP), the proposed CDPR has two redundancy, kinematic redundancy and actuation redundancy. The kinematic redundancy contributes to avoiding collisions between cables, and the actuation redundancy is used for control the cables' tensions. The proposed CDPR has large workspace by avoiding the cables' collisions, and high precision by keeping the tensions of all cables as positive values. In this paper, control method for avoiding the cables' collisionsby the kinematic redundancy is discussed in detail.

Workspace analysis of a 6-DOF cable-driven parallel robot considering pulley bearing friction under ultra-high acceleration
Cable robots can generate high velocities and accelerations due to the very small inertia of the end-effector. Therefore, CDPRs have been used widely in special industrial applications requiring high dynamics. However, the high acceleration generated ...
