Abstract
A kinematic model which allowed for a compensation of the introduced hinge errors was presented. The dynamic model of compliant parallel robots was analytically derived. It was found that a consistency check of the analytic dynamic model with a simulation of the robot with the multi-body software ADAMS leads to very good results. With the new kinematic model the deviation of the compliant mechanism were minimized. It was demonstrated that this new model needs only a few additional computations compared to the formerly and can be easily implemented in a robot control. This model provided not only a good repeatability of compliant mechanisms but also a good absolute positioning accuracy.
