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...

accommodation of mechanism with human being’s physical characteristics creates the possibility of safe and efficient interaction between human being and robot. regarding the fact that amputation of a limb in human beings causes several mental, economical and social difficulties and problems, need to a substitute limb which has the most efficiency for the person after amputation is a vital need....

A steady-state dynamic model of a cable in air is put forward by using some tensor relations. For the dynamic motion of a long-span Cable-Driven Parallel Robot CDPR system, a driven cable deployment and retrieval mathematical model of CDPR is developed by employing lumped mass method. The effects of cable mass are taken into account. The boundary condition of cable and initial values of equatio...

A cable-driven parallel robot (CDPR) was developed for the installation of curtain wall modules (CWM). The research addressed question whether CDPR capable installing CWMs with sufficient accuracy while being competitive compared to conventional manual methods. In order develop and test such a system, conceptual framework that consisted three sub-systems defined. tests, carried out in two close...

An identi cation of the model parameters for a parallel cable-driven robot is performed by using both a calibration and a self-calibration approach. The manipulator studied is based on a parallel architecture having 8 cables to control the 6 degrees of freedom of its mobile platform so that the mobile platform is fully constrained by the cables. Under some hypotheses on cable properties, the in...

The wrench-closure workspace of parallel cable-driven mechanisms is the set of poses for which any wrench can be produced at the end-effector by a set of a non-negative cable tensions. It is already known that the boundary of the constant-orientation wrench-closure workspace of a planar parallel cable-driven mechanism is composed of segments of conic sections. Howevel; the relationship between ...

Kinematics and dynamics of cable-driven parallel robots are affected by the cables used as force and motion transmitting elements. Flexural rigidity of these cables is of major interest to better understand dynamics of these systems and to improve their accuracy. The approach for modeling spatial cable dynamics, as presented in this paper, is based on the modified rigid-finite element method us...

Cable-driven parallel robots are mechanisms that control the position and attitude of an object using multiple cables. Typical cable-driven have been studied for use on land, but not in water. This is because motion analysis become difficult underwater due to large deformation cables caused by fluid forces. In this paper, we propose robot consisting on-water derive a dynamics model considers ca...

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...
