Description

Instruction manual Name: Robot, system and corresponding method with automatic return charging function

[0001] The present invention relates to the field of artificial intelligence, and more particularly to a robot with an automatic return charging function

, system and corresponding methods.

Background technique

[0002] At present, various robots that need to be charged, their automatic charging is to continuously send signals through the charging base, and then the receiver at the top of the automatic sweeping machine receives the signal, and finally finds the "home" road; in the field of cleaning robots It uses 3 kinds of positioning technology: infrared positioning, Bluetooth positioning, radar positioning; currently about 70 <3⁄4 models on the market are using infrared positioning.

[0003] Infrared positioning, although high precision, is because this kind of light can't penetrate the object, so that the infrared light can only be positioned within the line of sight. Just like the infrared light used in our TV remote control, if something is blocked, it will be lost. The signal. For smart vacuum cleaners, it often works in dusty environments. Some dust debris can easily interfere with the infrared receiving window on the fuselage, and infrared rays are easily interfered with indoor fluorescent lamps during transmission, so there will be intelligence. The vacuum cleaner cannot find the charging base.

[0004] Another automatic sweeper uses ultrasonic positioning to find a charging base. Ultrasonic waves mainly locate objects by reflective ranging, similar to bats calculating the distance between an object and itself by triangulation, and ultrasonic ranging is multipath. Effect and non-line-of-sight propagation have a great influence on the manufacturing cost of the circuit. Currently, few robot vacuum cleaners use this principle.

[0005] There is also a Bluetooth technology, Bluetooth is positioned by measuring the strength of the model, its power is relatively low, the positioning system made by Bluetooth is relatively small, very easy to integrate in the automatic sweeper circuit, using this technology It is not easily affected by the line of sight, that is, it can be positioned within a straight line even if obstacles are blocked.
