On the accuracy of $N-1$ wire-driven parallel robots [PDF]
, 2013 A $N-1$ wire-driven parallel robot is a robot for which all the $N \ge 3$ wires are connected at the same point of the platform, allowing to control the location of this point. We are interested in the positioning accuracy of such a robot.

A new methodology for designing PD controllers [PDF]
, 2001 It is known that it is impossible to select fixed gains for a PD controller that will critically damp the response to disturbances for all configurations of a given robot system. Because of this the potential for overshoot is always present and cannot be
