Landmark positioning robot system and landmarks and robots used thereby, and robot landmark positioning method

Abstract

The present invention relates to the field of robot technology, and in particular to a landmark positioning robot system and landmarks and robots used thereby, and a robot landmark positioning method.A robot positioning landmark comprises an RFID card and a non-central symmetric graphic identity. A landmark positioning robot comprises a robot body with a mobile function, an RFID card reader, anda camera module. A RFID card reader antenna is disposed on the bottom of the robot. The bottom of the robot is provided with a shooting window. The camera module is disposed in the robot body and thecamera shoots the window toward the bottom of the robot. A landmark positioning robot system comprises a plurality of the above landmarks and at least one of the above robots, and a host computer. Thehost computer comprises a wireless communication module, and the robot also comprises a wireless communication module.

[0002] At present, with the development of robot technology, storage robots and sorting robots have achieved good results in handling and sorting operations in standardized areas. Mobile robots, especially VGA robots, are highly dependent on landmarks. Amazon's kiva Taking the robot system as an example, it uses two-dimensional code landmarks to assist robots in positioning themselves and achieve navigation. Landmarks are particularly important for robots that rely on landmarks for self-positioning. With the rapid development of information technology, two-dimensional codes are widely used in various enterprises and various industries. For products, the QR code collects relevant information about the company and its products. By scanning the QR code, relevant information can be obtained. It can also be used as a landmark to mark the current location information. The robot will navigate and move according to the current location and the target location of the robot. However, only using two-dimensional code landmarks has higher requirements on the working environment of the robot. The robot may not be recognized or misrecognized due to ambient light interference or two-dimensional code landmarks. In addition, the camera needs to continuously capture and record each frame of the video image. For identification and judgment, when the robot runs at a high speed, there are high requirements for the number of frames of the camera and the shutter speed; another method is to use the RFID card as the landmark of the robot, and the robot reads the current time through its own RFID card reader. The position information corresponding to the read RFID card, but due to the non-contact characteristics of the RFID card, it is not easy for the robot to judge the precise position when reading the card, and it is even more difficult to judge the current orientation information of the robot by reading an RFID card; in the warehouse Professional robots in the field of logistics and sorting operate in a systematic group. When individual landmarks cannot be read or the positioning of the robot is inaccurate, it will have a great impact on the stable operation of the robot system.
