Abstract

The invention relates to a robot position detecting device and method. The method includes the steps that a robot is powered on, and the first position information of a single-ring absolute value encoder at this moment is read; the first position information and zero-point position information are calculated, so that position information of an actuating mechanism is obtained, and the zero-point position information is the position information corresponding to the single-ring absolute value encoder when the actuating mechanism is located at an absolute zero point position; and afterwards, an incremental encoder is used for detecting the position information of a first output shaft. No back-to-zero operation is required when the robot is restarted after power failure, the battery memory position does not need to be added after power failure, either, and there is no need to obtain the actual position of the robot by finding reference points again. Assembling is easy, the structure is flexible, and cost is low. The update speed of the position information is high, and precision is also high. The response performance and working efficiency of the robot can be better improved.

Description

technical field [0001] The invention relates to the technical field of position detection, in particular to a robot position detection device and method. Background technique [0002] In the field of robot technology, the position detection method of the robot basically uses the encoder on the servo motor as the position feedback device of the robot. The traditional encoder and detection method cannot memorize the current position of the robot after power off. The actual coordinate position of the robot must be obtained by re-finding the reference point; if you add a battery-powered memory position to the encoder, it will be troublesome to replace the battery, or the battery voltage may be insufficient and the position memory will be lost, requiring re-zeroing. Therefore, the robot position detection process is complex and cumbersome. Contents of the invention [0003] Based on this, it is necessary to provide a robot position detection device and method for the complicat...
