Kinematic calibration of a parallel robot using coordinate measuring machine
In the applications of parallel robots, kinematic calibration is required to eliminate the errors resulting from the manufacturing and assembly. In this paper, a new method for calibrating a parallel robot is proposed. An error model for kinematic calibration is constructed using differential geometry method. All leg length information and pose error are obtained based on measurement results co...
متن کاملLaser Tracker Calibration Using Coordinate Measuring Machine
This paper presents the achievement of a China NSFC project. A technique to calibrate laser tracker using CMM has been developed. A laser tracker with working range of 35m can be calibrated accurately and quickly using a CMM with working range of 1m. Studies have shown that angular errors are the key contributor to measuring errors of laser tracker. A device to measure angular errors of laser t...

متن کاملArticulated Arm Coordinate Measuring Machine Calibration by Laser Tracker Multilateration
A new procedure for the calibration of an articulated arm coordinate measuring machine (AACMM) is presented in this paper. First, a self-calibration algorithm of four laser trackers (LTs) is developed. The spatial localization of a retroreflector target, placed in different positions within the workspace, is determined by means of a geometric multilateration system constructed from the four LTs...
متن کاملThe Uncertainty of Parallel Model Coordinate Measuring Machine
The Stewart platform is one of 6-DOF (6 degrees of freedom) parallel mechanism. A parallel mechanism is a mechanism to connect six actuators in parallel between the base and the stage. It is necessary to calibrate the kinematic parameters that compose the mechanism in order to use the parallel mechanism as the coordinate measuring machine. Additionally, it is necessary to estimate the uncertain...
