基于可测距平板工具的机器人TCP标定方法
Robotic TCP calibration method based on plane toolbar with dis-tance measure function
摘要
Abstract
For the Tool Center Point(TCP)calibration of an industrial robot, a calibration based on a calibration toolbar function with two-dimensional ranging is proposed. The calibration toolbar is capable of sensing the touch of the robotic TCP and measuring the distance between any two contact points. Robotic TCP touches the calibration toolbar four times and the TCP parameter calibration model can be established for the constraint that the length of line segments formed by the contact points is the coordinate transformation invariants. The model includes a ternary quadratic algebraic equation set. All possible solutions can be found out through the elimination method and the determination method of the real solution is proposed. The method is proven to be feasible by numerical simulation. Resistive touch screen used as the calibration toolbar, for example, the resolution of two-dimensional calibration ranging toolbar influence on calibration accuracy is researched and calibration experiments results show that the method has high accuracy. The calibration whose process is simple and easy for automatization can be applied for most robots.关键词
