Abstract
Four-cable driven camera robot is a kind of rope-driven parallel robot. An improved forward kinematics algorithm based on its configuration is proposed
which does not involve solving the derivative of the Jacobi matrix and its inverse
fast and accurate solution of kinematics of this mechanism is carried out. By comparing with Newton iteration method
it is shown that the improved algorithm greatly improves the operation speed with the same precision
and the validity
accuracy and practicability of the algorithm are verified through numerical experiments.
