Problems solved by technology

Therefore, the robot manufactured by existing technology has a low success rate in the process of automatic charging guidance, which requires multiple attempts and adjustments, and even the robot is very close to the charging station but has not been able to complete the guidance.
Some technologies use infrared ranging technology to test the distance according to the phase of the received echo. The receiving strength of this method is susceptible to external interference, and the equipment cost of the phase difference can be judged.

Embodiment 1

[0091] Such as Figure 10 As shown, the intelligent robot 100 enters the infrared emission range from the roaming state, and the large-angle receiver FG receives the infrared signal and arrives at the position 80 . There is no need to judge the signal type, the robot rotates itself, and records the angle at which the signal is lost on the two steerings, so as to calculate the intermediate angle. The robot turns to the middle angle, moves forward 1.5m, and enters the full coverage of 5.7m. Arrived at position 81. The robot rotates until the small-angle receiver H receives the infrared signal. At this time, the rotation angle is about 180 degrees. After that, the small-angle receiver H is used to scan the infrared signal and adjust the robot's posture. In appearance, the robot moves backward. . The receiver H analyzes the received infrared signal, calculates the duty cycle, and counts the pulses of the corresponding type. The duty cycle of area 2 is 40%. During the rotation ...

Abstract

The invention provides a robot autonomous charging docking system and method. According to the robot autonomous charging docking system and device, an infrared emitting module of a fan-shaped infrared emitting array formed by a plurality of infrared emitting tubes alternatively sends infrared pulse signals at intervals, an infrared receiving module comprising a DSP control module collects the infrared pulse signals, the district where a robot locates is parsed out according to the infrared pulse signals, a motion control module controls a motor of the robot according to the district where the robot locates, and the motor drives the robot to adjust the advancing direction to enable the robot to be close to a charging station. The robot autonomous charging docking system and device uses the fan-shaped arranged infrared emitting array, each infrared emitting tube is small in emitting angle and long in emitting distance, so that the emitting array as a whole can be provided with a far emitting distance and a large emitting angle, and therefore the guidable range can be enlarged.

Description

technical field [0001] The invention relates to the technical field of robot charging, in particular to a robot autonomous charging and docking system and method. Background technique [0002] With the continuous improvement of automation technology, people's demand for automation and intelligence of living facilities is getting higher and higher. In recent years, various life service robots have sprung up in the market, such as cleaning robots, tour guide robots, and consulting robots. These robots have some common characteristics, such as small and fixed range of motion, and poor battery life. Therefore, the automatic charging technology came into being. When the robot's power is low, the robot is guided to the charging station by itself in a certain way, and then automatically starts working after charging. This eliminates the need for frequent manual charging. [0003] In the prior art, methods for indoor navigation mainly include laser navigation, ultrasonic detectio...
