Workspace Analysis of 6–6 Cable-Suspended Parallel Robots
N, Cable Driven Parallel Robots (CDPRs), the moving platform is connected to the base platform by a number of cables. CDPRs have several advantages compared to traditional serial or parallel robots. They have high ratio of payload to robot weight and a much larger workspace which make them appropriate for high speed applications [1], lifting heavy loads [2], camera positioning in sports stadium...
متن کاملModeling and Wrench Feasible Workspace Analysis of a Cable Suspended Robot for Heavy Loads Handling
Modeling and Wrench feasible workspace analysis of a spatial cable suspended robots is presented. A six-cable spatial cable robot is used the same as Stewart robots. Due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. Various workspaces are defined and the results of simulation are presented on the basis of various workspaces and app...
متن کاملRandomized Kinodynamic Planning for Cable-suspended Parallel Robots
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...
متن کاملOn the robustness of cable configurations of suspended cable-driven parallel robots
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...
متن کاملCable-suspended planar parallel robots with redundant cables: controllers with positive cable tensions
Cable-suspended robots are structurally similar to parallel actuated robots but with the fundamental difference that cables can only pull the end-effector but not push it. From a scientific point of view, this feature makes feedback control of cable-suspended robots lot more challenging than their counterpart parallel-actuated robots. In the case with redundant cables, feedback control laws can...
