专利汇可以提供Calibration system for robot visual coordinate system专利检索,专利查询,专利分析的服务。并且PURPOSE:To calibrate the shift between a fixed visual coordinate system and a robot coordinate system and to secure the accurate working of a robot, by calculating a space error produced when a fixed sensor is attached to the robot coordinate system. CONSTITUTION:A robot 1 and a visual fixed tool 7 are attached to a robot attachment stage 2, and a fixed visual sensor 3 is attached to the tool 7. Then the robot 1 is moved in response to the position/posture command value given from a robot controller 6. The picture of the robot 1 obtained after movement of the robot is fetched by the sensor 3 and sent to a picture processor 4. The processor 4 measures the position and posture of the robot 1. While an error calculator 5 calculates the position and posture of the robot 1 in a fixed visual coordinate system based on said command value given from the controller 6. Based on this result of calculation and said measured value, an attachment error of the sensor 3 is calculated. Then the shift between the robot coordinate system and the fixed visual coordinate system is calibrated in accordance with said error.,下面是Calibration system for robot visual coordinate system专利的具体信息内容。
