Accuracy of Four Parallel Manipulator

Article Preview

Abstract:

The Due to the error, parallel manipulators always exhibit some position and orientation errors at the mobile platform. The analysis of accuracy is carried out to find the source errors which affect the pose accuracy of the end-effecter in terms of the error model. The accuracy synthesis is implemented to obtain the geometry tolerance of the major parts affecting the uncompensable pose error. In order to finish these works, one method is proposed, which can also be used to handle the similar mechanism
