Problems solved by technology

[0007] In a strong light environment, the receiving tube 3 is easily saturated, and in a light-absorbing environment, the amount of reflected light received is small. Both of these environments will cause the module to lose its detection ability

Embodiment Construction

[0027] Embodiments of the present invention provide a cliff detection method, device, equipment, and robot for cliff detection by an optical transceiver. The embodiment of the present invention can control the optical transceiver device to select to enter different detection modes according to the current environment, so as to avoid the detection accuracy of the optical transceiver device from being affected by the environment.

[0028] Please see figure 1 and figure 2 , the intelligent robot 99 includes a main body 10 and a cliff detection device 20 arranged on the main body 10 . The bottom 11 of the main body 10 is provided with a pulley (not shown in the figure) to drive the intelligent robot to move on the ground. The cliff detection device 20 includes a cliff detection device 21 and an optical transceiver device 22 . The optical transceiver device 22 is disposed on the bottom 11 . The cliff detection device 21 implements the cliff detection method and uses the optica...

Abstract

The invention provides a cliff detecting method which comprises controlling an optical transceiver to enter a strong light detecting mode, a weak light detecting mode or a normal light detecting mode;detecting a first light parameter currently generated by the optical transceiver if the optical transceiver enters the strong light detecting mode and determining whether there is a cliff according to the first light parameter and a first threshold; detecting a second light parameter currently generated by the optical transceiver when the optical transceiver enters the weak light detecting mode and determining whether there is the cliff according to the second light parameter and a second threshold; detecting a third light parameter currently generated by the optical transceiver if the optical transceiver enters the normal light detecting mode and determining where there is the cliff according to the third light parameter and a third threshold. According to the cliff detecting method, cliff detection can be performed under various light environments and is not affected by ambient light. The invention also provides a cliff detecting device and apparatus and a robot.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a cliff detection method, device, equipment and robot. Background technique [0002] Cleaning robots are special robots that serve human beings, mainly engaged in household cleaning, cleaning and other cleaning tasks. With the development of artificial intelligence, cleaning robots have added functions such as intelligent obstacle avoidance, self-rescue and anti-jamming, automatic charging, and autonomous navigation path planning, which greatly improves the intelligence of cleaning robots. The entire cleaning process does not require human control, which greatly liberates People's hands, the cleaning process saves time and effort, and is more and more popular among young people. [0003] However, cliff detection in strong light and light-absorbing environments is still a major problem for cleaning robots. In the prior art, there are many methods for cliff detection in...
