Cable-driven parallel robot (CDPR) are parallel robots that use coilable cables as legs. We are interested here in suspended CDPR for which there is no cable that exert a downward force on the platform. If we assume that the cables are mass-less and not elastic it has been shown that at a given pose whatever is the number m > 6 of cables there will always be at most 6 cables under tension simul...

Abstract Cable-driven hyper-redundant robots have been adopted in many fields for accessing harsh and confined environments that maybe inaccessible or dangerous humans. The cable actuation strategy makes the robot hardware safer increases payload reducing its weight. In this paper, a novel design of fully actuated cable-driven has proposed. This solution is pulleyless decreases mechanical compl...

Cable Driven Parallel Robots (CDPRs) are parallel robots, in which the limbs replaced by cables that guided pulleys. In many papers, pulleys considered as fixed points of passage and cable elasticity is neglected. Those approximations simplify robot modelling, but lead to some Moving-Platform (MP) pose errors. This paper deals with modelling suspended three degree-of-freedom CDPRs considering g...

Accurate, real-time information about the aging status of the power distribution cable network can save the power industry millions of dollars lost due to line failures and premature replacement of cables. Hence, a novel, semiautonomous robotic sensor platform has been developed for monitoring underground, power distribution cable systems. A segmented, legged modular configuration allows the ro...

This paper addresses the topological and dimensional synthesis of cable-driven parallel robots. A combined methodology for type size optimization is proposed applied to a cable driven robot, which intended upper-limb rehabilitation exercises. The approach deals with set deterministic non-deterministic parameters within multi-objective genetic algorithm. study aims select suitable architecture h...

This paper proposes a control strategy for a cable‐suspended robot based on an optimal sliding mode approach confronted by external disturbances and parametric uncertainties. This control algorithm is based on the Lyapunov technique, which is not only able to provide the stability of the end‐effector with an acceptable precision but also provides the optimal path in...

Cable array robots are a class of robotic mechanisms which utilize multiple actuated cables to manipulate objects. This paper discusses the defining characteristics and the important issues relating to this class of robots. One particular type of cable array robot with three cables is presented in detail including kinematic relations and dynamic modeling. The resulting models are used to design...

Now robot assisted laparoscopy has some problem to depend only on image of the surgical field. However, there is a research result which shows that it is possible to measure the operation force on commercialized instrument inside patient without sensors [1]. By using measured information, haptic technique can be implemented into surgical robot system. Therefore, this paper proposes the design o...

The presented controller system has been designed and dedicated to the intuitive and instinctive cable driven robot manipulator. The described robot manipulator is the moving platform suspended by the set of six variable-length steel cables. In practice the construction is like a standard inverted Stewart platform the platform is able to move in all six degrees of freedom with respect to its ba...

This paper proposes the use of a randomized kinodynamic planning technique to synthesize dynamic motions for cable-suspended parallel robots. Given two mechanical states of the robot, both with a prescribed position and velocity, the method attempts to connect them by a collision-free trajectory that respects the joint and force limits of the actuators, keeps the cables in tension, and takes th...
