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] like 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 reaches the position 80 . Without judging the type of signal, the robot rotates, and records the angle at which the signal is lost on the two turns to calculate the intermediate angle. The robot turns to the middle angle, moves forward 1.5m, and enters the full coverage area of ​​5.7m. Reach 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. The robot moves backwards. . The receiver H analyzes the received infrared signal, calculates the duty cycle, and counts the corresponding type of pulses. The duty cycle of area 2 is 40%. During the rotation of the receiver H, the number of pulses with a ...

Abstract

The invention provides a robot autonomous charging and docking system and method. The infrared transmitting module of a fan-shaped infrared transmitting array composed of several infrared transmitting tubes transmits infrared pulse signals at intervals, and then the infrared receiving module including a DSP control module collects all the infrared pulse signals. The infrared pulse signal is used to analyze the current area of ​​the robot according to the infrared pulse signal. The motion control module controls the motor of the robot according to the area where the robot is located. The motor drives the robot to adjust the traveling direction so that The robot is close to a charging station. The invention provides a robot autonomous charging and docking system that uses an infrared emission array arranged in a fan shape. Each infrared emission tube has the characteristics of small emission angle and long emission distance, so that the emission array as a whole can have a long emission distance. Larger launch angle, thereby increasing the range that can be guided.

Description

technical field [0001] The invention relates to the technical field of robot charging, in particular to a robot autonomous charging 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 into the market, such as cleaning robots, tour guide robots, consulting robots, etc. These robots share some common characteristics, such as a small and fixed range of motion, and poor battery life. So the automatic charging technology came into being. When the power of the robot is insufficient, the robot will be guided to the charging station by itself in some way, and then it will start working automatically after charging. This eliminates the need for frequent manual charging. [0003] In the prior art, the methods used for indoor navigation mainly include laser navigat...
