Cable interference in cable-driven mechanisms (CDM) is a major challenge in their applications. The wrench closure workspace (WCW) in a fully constrained mechanism may not be realized unless cable interference is considered. This paper classifies all possible types of cable interferences for planar cable-driven mechanisms and presents an analytical solution to find the boundaries of the constant-orientation interference region. It is shown that interference between cables starts and ends when…

Geometric Determination of the Interference-Free Constant-Orientation Workspace of Parallel Cable-Driven Mechanisms
TLDR
These results provide a fast method to graphically represent all interference regions in the manipulator workspace, given its geometry and the orientation of its end effector.
Analysis of the wrench-closure workspace of planar parallel cable-driven mechanisms
TLDR
The case of planar parallel cable-driven mechanisms is addressed and theorems that characterize the poses of the wrench-closure workspace are proposed and used to disclose the parts of the reachable workspace which belong to the WCW.
Wrench-feasible workspace generation for cable-driven robots
TLDR
This method uses the available net wrench set, which is the set of all wrenches that a cable robot can apply to its surroundings without violating tension limits in the cables, to calculate the boundaries of the wrench-feasible workspace (WFW) for cable robots.

TLDR
This paper presents a detailed analysis of the constant-orientation wrench-closure workspace of planar three-degree-of-freedom parallel mechanisms driven by four cables, which is proved to be the union of two disconnected sets that may or may not exist.

Planar Cable-Direct-Driven Robots: Design for Wrench Exertion
TLDR
Results indicate that the cable interference constraint dominates which suggests the need for future design work to alleviate this interference, and presents the best design for planar cable-direct-driven robots and/or haptic interfaces with one degree of actuation redundancy.
Analysis of the Influence of Wires Interference on the Workspace of Wire Robots
TLDR
Algorithms are proposed that allow to study the influence of wire/wire and wire/end-Effector interference on the workspace, assuming a fixed orientation of the end-effector.
