ABSTRACT
Rehabilitation robots are usually made of rigid links which make them heavy. So their application is limited to the health clinics and does not have home use. Cable robots compensate these defects. They have an important defect that can only apply tension. This can substantially restrict the workspace of the robot. In this paper we introduce a configuration, which is combination of cables and springs for a two degrees of freedom (DOF) planar cable robot. Parameters of springs are obtained through an optimization process. Static and dynamic workspace for this robot then calculated for different configurations of springs calculated on design process. We choose the configuration that has the widest dynamic and static workspace and compare to a different two DOF with two actuators cable robot.

Workspace Analysis of a One Cable Planar Cable Robot
ICMRE 2018: Proceedings of the 2018 4th International Conference on Mechatronics and Robotics EngineeringRehabilitation robots are usually made of rigid links which make them heavy with limited Workspace. Cable robots are introduced in rehabilitation to compensate these weaknesses. However, cable robots have an important weakness that they can only apply ...
Reconfigurable workspace and torque capacity of a compliant ankle rehabilitation robot (CARR)
The novelty of this paper is the adjustable workspace and torque capacity of a compliant ankle rehabilitation robot (CARR). The robot has three rotational degrees of freedom (DOFs) redundantly actuated by four compliant actuators. It suffers from ...
Inverse Kinematics and Workspace Analysis of a 3 DOF Flexible Parallel Humanoid Neck Robot
To mimic the human neck's three degree-of-freedom (DOF) rotation motion, we present a novel bio-inspired cable driven parallel robot with a flexible spine. Although there exists many parallel robotic platform that can mimic the human neck motion, most ...
