Embodiment 1

[0067] Please refer to Figure 2 to Figure 5 , this embodiment provides a robot automatic charging guidance method, which can guide the difficulty and significantly improve the guidance efficiency.

[0068] The method of this embodiment is realized based on the robot automatic charging guidance system, please refer to Figure 4 and Figure 5 , the system includes a robot 1 and a charging stand 2; the robot 1 is provided with a laser emitting module 13, a laser detection module 14, an infrared receiving module 12 and a charging control module 11, and the laser emitting module 13, the laser detection module 14 and the infrared The receiving module 12 is connected with the charging control module 11 respectively; the infrared emitting module 22 made of at least two infrared emitters, at least two laser reflectors ( Figure 5 In the first laser reflector 24 and the second laser reflector 25) and the charging output control module 21, more than two infrared emitters are arranged ...

Embodiment 2

[0089] This embodiment is further expanded on the basis of the first embodiment to improve the efficiency of the robot identifying the charging base based on the laser reflector. The same parts will not be repeated, and the difference is that, before step S1 of the first embodiment, a process of navigating and locating the charging stand is also included.

[0090] Specifically, the navigation and positioning charging stand process includes:

[0091] S01: The robot generates a navigation path with a preset distance from the self-positioning information to the charging stand positioning information according to its own positioning information and the preset charging stand positioning information.

[0092] Wherein, the positioning information of the robot itself is acquired by the navigation and positioning module on it, and the positioning information of the charging stand is preset and can be set through the client, such as specifying the position of the charging stand on the m...

Embodiment 3

[0097] This embodiment corresponds to Embodiment 2, and provides a robot automatic charging guidance system, please refer to Figure 4 and Figure 5 , including: robot 1 and charging stand 2;

[0098] The charging stand 2 includes more than two laser reflective plates (the first laser reflective plate 24 and the second laser reflective plate 25 in the figure) surrounding the charging stand, and more than two laser reflective plates surrounding the charging stand. Infrared emitter (constitutes the infrared emission module 22 in the figure); Also includes charging output control module 21 and robot identification module 23;

[0099] Each of the reflectors is used to reflect and scatter the laser signal after receiving the laser light emitted by the robot;

[0100] Each of the infrared emitters is used to send infrared signals with their own characteristics in time-sharing; specifically, the control signal of the charging output control module will be obtained, and an infrared ...

Abstract

The invention provides a method and a system of guiding a robot to be recharged automatically. The method comprises steps that the robot emits laser while doing spiral motion; the robot detects a laser signal reflected by a reflective board on a recharge stand and then calculates and acquires a direction of the recharge stand relative to the robot according to the laser signal; and the robot is driven to a corresponding position according to the direction. The method combines navigation, laser initial recognition and infrared accurate guide, thereby guiding the robot to be recharged automatically more efficiently and lowering guiding difficulty; further, compared with the radar matching and image matching-based guiding manners, the method reduces realization cost and lowers equipment configuration requirements, is particularly suitable for guiding in a large area, and has remarkable effect.

Description

technical field [0001] The invention relates to the technical field of automatic charging, in particular to a robot automatic charging guidance method and system thereof. Background technique [0002] The application of service robots is becoming more and more widespread, and the degree of intelligence of robots is getting higher and higher. Automatic charging has become an essential function of intelligent robots. Finding a charging stand quickly and efficiently is an important part of determining the experience of using a robot, so it is an important direction in the field of robotics research. [0003] The automatic charging scheme in the prior art generally guides the robot through the infrared signal of the charging stand or laser radar matching, charging stand image matching and other methods, and then charges the robot after guiding it in place. This infrared guided charging method has problems such as short guidance distance requirements, large errors, long time-con...
