Module landmark and landmark for robot walking and robot

Abstract

The invention discloses a module landmark and landmark for robot walking and a robot. According to the module landmark, the whole area of robot walking is divided into multiple module areas. A first magnetic block and a second magnetic block are arranged in each module area, wherein the polarity of the first magnetic block is N pole or S pole, and the polarity of the second magnetic block is different from that of the first magnetic block. Each first magnetic block is a first magnetic strip, and each second magnetic block is a second magnetic strip. Each first magnetic strip is arranged in the Y-axis direction. Each second magnetic strip is arranged in the X-axis direction. Each module area further comprises a third magnetic strip and a fourth magnetic strip, the four strips of each module area are arranged in a cross shape, and the polarity of each second magnetic strip, the polarity of the corresponding third magnetic strip and the polarity of the corresponding fourth magnetic strip are the same. Multiple magnetic induction sensors and an address landmark recognition device are mounted at the bottom of the robot. The robot can advance, retreat, turn and walk to the target module areas according to commands and collected landmark information. The module landmark and landmark for robot walking and the robot have the beneficial effects that locating is reliable and accurate, and maintenance is convenient.

Description

technical field [0001] The invention relates to a modular landmark for robot walking, a landmark and a robot thereof. Background technique [0002] Robots can navigate in a variety of ways when transporting and unloading goods, for example, they can navigate by GPS or by landmarks. When robots are used to sort packages, a sorting system has hundreds of robots moving at the same time. At present, the more common way is to collect landmark information for navigation. The most common landmark information is the two-dimensional code. The two-dimensional code includes both the direction signal and the position signal. The robot moves from one module area to another. When in a region, continuously read the QR code information, and make actions such as going straight, reversing or turning according to the instruction robot. The QR code has a good error tolerance rate and can be decoded even if some information is lost. The QR code four The information of four corners represents ...

[0002] Robots can navigate in a variety of ways when transporting and unloading goods, for example, they can navigate by GPS or by landmarks. When robots are used to sort packages, a sorting system has hundreds of robots moving at the same time. At present, the more common way is to collect landmark information for navigation. The most common landmark information is the two-dimensional code. The two-dimensional code includes both the direction signal and the position signal. The robot moves from one module area to another. When in a region, continuously read the QR code information, and make actions such as going straight, reversing or turning according to the instruction robot. The QR code has a good error tolerance rate and can be decoded even if some information is lost. The QR code four The information of four corners represents the direction information, which can be used to judge the direction of the robot. When one of the four corners of the two-dimensional code fails to be read, the direction cannot be judged, due to the wear and tear of the two-dimensional code, foreign objects, etc. , there will be a phenomenon of reading failure
