Using geometric model deformations under an external collision, direct relationship esta...

Abstract This paper discusses stiffness and antagonistic actuation in light-weight cable-driven bio-inspired manipulators suitable for safe interactions. Manipulators under study are built upon arranging series several tensegrity joints, called “modules.” A comparative of modules revealed that the X module, contrast to based on pivots, allows one increase joint by increasing input forces like d...

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 ...

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...

We propose a new approach for the reliable 6dimensional quasi-static manipulation of an aerial towed-cable system. The novelty of this approach lies in the combination of results deriving from the static analysis of cable-driven manipulators with the application of a cost-based motion-planning algorithm to solve manipulation queries. Using this approach, we can ensure that the produced paths ar...

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...

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 (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...
