Error Analysis in Solving the Inverse Problem of the Cable-driven Parallel Underactuated Robot Kinematics and Methods for their Elimination

摘要

An analysis of the geometry of a cable-driven parallel robot is carried out. The influence of the design of the guide rollers and the winding mechanisms on the errors in the determination of the cable length control laws was investigated. Two variants of the arrangement of the spools in the winch mechanisms are considered. The analysis of the magnitudes of the resulting errors is given, the conclusion is made that it is necessary to take into consideration the design of the guide rollers and the winding mechanism with the vertical position of the spool, and also the permissibility to ignore the influence of the winding mechanism with the horizontal position of the spool.
