Abstract The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is the largest single-dish aperture telescope with a cable-driven parallel robot introduced to achieve highest sensitivity in world. However, realize high-precision, mechanical equations of such are always complicated, so that it difficult real-time control by traditional iterative method. In this regard, paper proposes a...

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 addresses the direct geometrico-static analysis of under-constrained cable-driven parallel robots with 3 cables. The task consists in finding all equilibrium configurations of the end-effector when the cable lengths are assigned. An interval-analysis-based procedure is proposed to numerically find the real solutions of the problem for a robot of generic geometry. Three equation sets ...

This paper investigates the singular curves in the joint space of a family of planar parallel manipulators. It focuses on special points, referred to as cusp points, which may appear on these curves. Cusp points play an important role in the kinematic behavior of parallel manipulators since they make possible a nonsingular change of assembly mode. The purpose of this study is twofold. First, it...

The direct geometrico-static problem of cable-driven parallel robots with 5 cables is presented. The study provides procedures for the identification of all equilibrium poses of the end-effector when cable lengths are assigned. A leastdegree univariate polynomial in the ideal governing the problem is obtained, thus showing that the latter has 140 solutions in the complex field. By a continuatio...

This paper examines the design, analysis and control of a novel hybrid articulated-cable parallel platform for upper limb rehabilitation in three dimensional space. The proposed lightweight, low-cost, modular reconfigurable parallel-architecture robotic device is comprised of five cables and a single linear actuator which connects a six degrees-of-freedom moving platform to a fixed base. This n...
