In this study, we investigated dynamic control strategies for over-constrained cable-driven robots. order to a robot, it is essential address issues that arise from the restriction of cable tension, as well redundancy an system. contrast previous research required consideration relationship between tension constraints and computed wrench in distribution problems, developed function incorporates...

This work presents the status of running project (2007–2010). The new nine degrees of freedom cable driven robot has been developed. Main parts: the mechanical design of parallel manipulator and the heart of control system have been presented. The preliminary tests of the prototype application have been performed. As the final result of the project, a robotic cable driven crane will be develope...

cable driven parallel manipulator (cdpm) is a special class of parallel manipulator in which the rigid extensible links are replaced by actuated cables. it is necessary to take into consideration the cable dynamics, i.e.; its mass, flexibility and curved shape for manipulating a long-span cdpm. these terms complicate governing equation of motion in a way that special tactic are applied for simu...

In this paper, an interval based approach is proposed to rigorously identify the model parameters of a parallel cable-driven robot. The studied manipulator follows a parallel architecture having 8 cables to control the 6 DOFs of its mobile platform. This robot is complex to model, mainly due to the cable behavior. To simplify it, some hypotheses on cable properties (no mass and no elasticity) a...

This paper addresses the cable tension distributions of a cable-driven parallel robot with non-negligible cable mass for large dimension mechanisms. A well-known model which describes the profile of a cable under the action of its own weight allows us to take the cable sags into account. In addition, an approach to computing the cable tensions is presented, in which there are two major steps to...

This paper presents a reconfigurable cable parallel robot, which spatial topology can be reconfigured through managing the branch numbers and the hoisting points of the end-effector. An experimental prototype of the reconfigurable cable parallel robot is designed and developed. A typical configuration of the reconfigurable cable parallel robot is analyzed as a case study. The finite element ana...

Planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. The problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. Open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

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...
