METHOD AND SYSTEM FOR ENABLING ROBOT TO AUTOMATICALLY RETURN FOR CHARGING
Document Type and Number:
WIPO Patent Application WO/2018/077164
Kind Code:
A1
Abstract:
A method and system for enabling a robot (100) to automatically return for charging, relating to the technical field of automation. The method comprises: obtain current visual field information by means of a robot (100) (S110); accordingly determine whether a target system is within the range of the current visual field information (S120); if the target system is within the range of current visual field information, photograph the target system, so as to obtain a first image (S131); process the first image to obtain a black-white image (S140); establish a Cartesian coordinate system according to the black-white image, and control, according to the Cartesian coordinate system, the robot (100) to move to a preset correction point (S150); then the robot (100) sends a drive instruction to the target system, so that the target system feeds back a pulse signal to the robot (100) according to the drive instruction (S160); the robot (100) aligns with the target system; after the alignment ends, start charging the robot (100) (S190). In the present invention, the equipment costs of the obstacle avoidance and navigation of the robot (100) can be reduced, and the stability, accuracy and practicability of the walking state of the robot (100) can be improved.
