Optimal pose selection for vision-based kinematic calibration of parallel mechanisms
نویسندگان
چکیده
In this paper, a new pose selection criterion for the kinematic calibration of parallel mechanisms is proposed. It enables one to take into account the measurement noise amplification that may occur for parallel mechanisms, as well as the variation of amplitude and anisotropy of the measuring device accuracy. This new criterion is applied to vision-based calibration of an Orthoglide mechanism, both in simulation, with comparison to existing criteria, and experimentally.

Kinetostatic performances of ten different planar parallel mechanisms are analyzed by resorting to a recent index, kinematic sens...
متن کاملVision-based kinematic calibration of an H4 parallel mechanism: practical accuracies
In this article, we present the kinematic calibration of a H4 parallel robot using a vision-based measuring device. Calibration is performed according to the inverse kinematic model method, using first the design model then a model developed for calibration purpose. To do so, the end-effector pose has to be measured with the utterst accuracy. Thus, we first evaluate the practical accuracy of ou...

متن کاملAn Approach for Optimal Design of Robot Vision Systems
The accuracy of a robot manipulator’s position in an application environment is dependent on the manufacturing accuracy and the control accuracy. Unfortunately, there always exist both manufacturing error and control error. Calibration is an approach to identifying the accurate geometry of the robot. In general, robots must be calibrated to improve their accuracy. A calibrated robot has a highe...
