Kinematics Control of 3-DOF Under-constrained Parallel Robot with Variable Cable Mast Angles
Jixie chuandong, 2022 The cable-driven parallel robot is a special type of parallel robots whose end-effector is driven by cables instead of rigid rods. A three-degree-of-freedom (3-DOF) under-constrained parallel robot with variable cable mast angle is studied.

Stability Analysis and Robust PID Control of Cable Driven Robots Considering Elasticity in Cables [PDF]
AUT Journal of Electrical Engineering, 2016 In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring.

Adaptive Fuzzy Control of a Cable-Driven Parallel Robot
Mathematics, 2022 Cable robots are a type of parallel robot in which cables have replaced the usual rigid arms. In cable robots, due to the tensile strength of the cable, the workspace analysis is much more complex than in conventional robots.

Interference detection for cable-driven parallel robots (CDPRs) [PDF]
2014 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2014 The main advantage of CDPRs is large workspaces. However, multiple legs and large workspace are both factors for interference. We consider a CDPR platform within a 6D workspace, and as sources of interference the collisions with the robot's environment and self interference.

Accuracy Improvement for CDPRs Based on Direct Cable Length Measurement Sensors
, 2021 S.348-359In many applications of cable-driven parallel robots (CDPRs), accuracy is an important requirement. The accuracy of CDPRs with a controller based only on the standard kinematic model is limited because of effects like cable elongation.
