Accurate measurement of robot track

The wide applications of industrial robots justifies the necessity to accurately measure their tracks. The relationship between the parameters of rods and the measuring space is analysed by comparing several ways to accurately measure the robot tracks with specific applications as typical examples for optimization of rod parameters. From the structural features of the measuring system, a mathematic model is constructed for the absolutely mechanical follow up system to perfect its operating principle. Solutions are proposed for the actual problems encountered during design of hardwares and softwares for the system. Actual applications show that this measuring system is in full compliance with the design requirements, features high sampling rate, good stability, simple operation and reliable operation, and can be used as a general measuring system for robot tracks.
