Abstract

The invention discloses a track robot positioning calibration device and calibration method, the calibration device comprises an RFID label and two magnetic nails, RFID is installed between the two magnetic nails, and the distance between each magnetic nail and the RFID label is at least 30 cm; and the track robot is provided with a non-contact RFID antenna and a Hall sensing device which are usedfor sensing the RFID tag and the magnetic nail. The calibration method comprises the steps that an RFID tag and magnetic nails on the two sides of the RFID tag are installed and fixed on a robot track, and initial position information of the RFID tag is set; and after setting is completed, the robot passes through the positioning device and then performs position calibration setting. According tothe technical scheme, a hybrid mode is adopted, the Hall sensing device and the RFID antenna are combined for application, and the problem of accurate calibration is effectively solved.

Description

technical field [0001] The invention relates to a positioning calibration device and a calibration method, in particular to a positioning calibration device and a calibration method for an orbital robot. Background technique [0002] There are several solutions for the current track robot positioning system. The first one uses the robot's built-in stopwatch for measurement and counting, and the second one uses external tags. For a motor-driven robot, the first method mainly includes a motor encoder, or an external motor rotation measuring instrument for measurement. This method can achieve high positioning accuracy under ideal conditions, but due to the high dependence on encoders, measuring instruments and environmental conditions, irreparable accumulation will occur in the case of slipping, insufficient fixation, offset, etc. error. The second method includes general external labels such as two-dimensional codes and RFID tags. Due to the single sensing method, large sen...
