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.

A reconfiguration strategy for Reconfigurable Cable-Driven Parallel Robots [PDF]
2015 IEEE International Conference on Robotics and Automation (ICRA), 2015 This paper deals with Reconfigurable Cable-Driven Parallel Robots (RCDPRs). A RCDPR is able to change the locations of its cable exit points, the latter being defined as the connection points between the cables and the robot base frame. Given a RCDPR, a set of possible reconfigurations, a desired platform path and a description of the robot environment,

Using Lie Derivatives with Dual Quaternions for Parallel Robots
Machines, 2023 We introduce the notion of the Lie derivative in the context of dual quaternions that represent rigid motions and twists. First we define the wrench in terms of dual quaternions.
