Description

technical field [0001] The invention relates to the application of robot autonomous positioning and navigation technology in the field of charging pile technology, in particular to the field of intelligent charging technology based on camera technology with a low degree of coupling with robots. Background technique [0002] More and more mobile robots are used in real life, such as sweeping the floor, tour guides, shopping guides, consulting robots, etc. People have higher and higher requirements for robots to be on duty for a long time, increase the range of activities, and extend the autonomy time. At present, mobile robots use high-quality onboard rechargeable battery packs to power themselves, but generally they can only last for a few hours. Once the power is exhausted, manual intervention must be used to charge the robot, which hinders the robot long-term autonomy. [0003] Due to the cableless power source of common mobile robots and the main dependence on high-quali...

AI Technical Summary

Problems solved by technology

[0005] (1) Semi-autonomous solution: mainly mechanical guidance, which is an auxiliary method added when the alignment error between the robot and the charging pile is relatively large. The auxiliary methods include guide rails, geomagnetism, horn-type charging interfaces, and adjustable power supply heads. The structure is relatively complex, the installation process is cumbersome, and the process of aligning and charging lacks flexibility, which has a great impact on the mechanical properties of the robot; the cost is relatively high, the environmental requirements are strict, and the degree of intelligence is very low.

[0006] (2) Autonomous solution: The main sensors used in the current technology include laser, infrared, sonar, camera, binocular camera, etc., and there are also fusions of various sensors. In general, robots play a dominant role in the charging and guiding process. , and the charging equipment is only a supporting equipment for a specific robot; at the same time, the management during the charging process is not intelligent enough to judge the charging status of the robot by itself, and there is too little interaction with the robot during the charging process; the time for the robot to return to the charging pile remotely is long and blind , low efficiency, and even before the battery capacity is exhausted, the robot cannot find the charging pile, causing the battery to over-discharge, causing damage to the battery or shutdown

[0008] (1) Low universality of charging piles: mainly refers to the low ability to adapt to different systems, platforms, mechanical properties, and shapes and sizes of waiting charging robots

[0009] (2) The guided charging success rate and efficiency of charging piles are low

[0010] (3) Complex structure and cumbersome installation process: Auxiliary alignment facilities such as guide rails, speaker charging ports, and geomagnetism are required, and complex adjustments to the structure of charging piles are made to compensate for alignment errors; autonomous guidance such as infrared and laser The installation process of charging equipment is complicated

[0011] (4) High cost: additional equipment and mechanical structure are required, so the cost is high

[0012] (5) The degree of intelligence is low

[0013] (6) The existing charging pile identification methods still have sensitive hardware characteristics, lack of universal environmental adaptability, unsatisfactory guidance accuracy, and insufficient error tolerance and error correction capabilities, and there are still gaps in the rationality, science, and economy of structural design. defect
