Automatic docking system of robot

Abstract

The invention provides an automatic docking system of a robot. The automatic docking system comprises the robot and a docking station, wherein a signal emitter is arranged on the docking station. The work principle of the automatic docking system is as follows: emitting a docking signal along an axis in front of a main body of the docking station so as to form a docking area with a preset angle; respectively emitting left and right docking guide signals on left and right sides of the docking area, wherein the transmission distance of the left and right docking guide signals is smaller than or equal to the transmission distance of the docking signal; and emitting a docking guide signal on the front side of a main body of the docking station, wherein the transmission distance of the docking guide signal is greater than the transmission distance of the docking signal. The robot is provided with a signal receiver for receiving signals from the docking station, after sensing the docking guide signal, the robot finds the left docking guide signal or the right docking guide signal following the docking guide signal, moves to the docking area along the outer edge of the left docking guide signal or the right docking guide signal, and moves following the docking signal to realize docking with the docking station. Compared with the closest prior art, the automatic docking system has the advantages of reduced power consumption and improved recharging efficiency.

Description

technical field [0001] The invention relates to robot automatic docking technology, in particular to an automatic robot docking system. Background technique [0002] A "robot" is one that performs work tasks while moving within a workspace without user manipulation. For example, robotic cleaners perform cleaning operations such as, but not limited to, sucking dirt, debris, or the like from floors; home robot monitors perform home monitoring; self-propelled mobile devices perform specific tasks, etc. Robotic cleaners generally include a driving wheel module and a power system for driving the robot cleaner to walk on the ground, a cleaning module for cleaning the ground while walking, and a control robot for cleaning according to the built-in program and avoiding obstacles The control system and various sensors used to detect the working environment. The robot can also use sensors or cameras to measure the distance to obstacles such as furniture, office supplies, or walls lo...

AI Technical Summary

Problems solved by technology

Although the automatic docking system can effectively guide the robot back to the docking station, since the left and right sides need to transmit signals with different strengths, and the docking signal transmitter in the middle needs to have enough transmission power to separate the left and right sides. The non-overlapping docking guide area increases power consumption and circuit complexity, and the long distance of docking signal transmission may also cause too many signals reflected by obstacles, making it easy for the robot’s signal receiver to be in the non-docking area. Misjudgment caused by receiving reflected signals reduces recharging efficiency
