Robot navigation method, apparatus and system, electronic device and storage medium

A robot navigation method, comprising:

• obtaining a first infrared signal, a second infrared signal and a distance signal;
• wherein the first infrared signal and the second infrared signal are infrared signals received by a first infrared receiver and a second infrared receiver disposed on a robot from an infrared transmitter disposed on a target device;
• the distance signal indicates a distance between the robot and the target device;
• controlling a moving direction of the robot according to the first infrared signal and the second infrared signal, so that the moving direction before the robot enters a docking scope is aligned with a docking interface on the target device, and
• determining whether the robot enters the docking scope based on the distance signal;
• in response to determining that the robot enters the docking scope, controlling the robot to move to the target device to dock with the target device, wherein the docking scope is defined by a predetermined infrared signal blind region, and the infrared signal blind region comprises an area where infrared radiation of the infrared transmitter is unable to cover the first infrared receiver and the second infrared receiver simultaneously, and the robot enters the infrared signal blind region and directly moves to the docking interface on the target device without using the first infrared signal and the second infrared signal and without changing the aligned moving direction, wherein entry of the robot into the infrared signal blind region is determined based on a known shape and location of the infrared signal blind region, and the entry into the infrared signal blind region serves as an indicator that the robot is aligned with the docking interface of the target device, and as a trigger to initiate a straight-line docking of the robot without changing the aligned moving direction, and the infrared signal blind region is predetermined based on an infrared radiation region of the infrared transmitter as well as a distance between the first infrared receiver and the second infrared receiver.
