Obstacle-avoidance system

Abstract

Embodiments of the invention provide an obstacle-avoidance system. The system comprises a mobile body which is provided with a moving assembly, a detector used for detecting a ground undulation state and a controller used for controlling a moving state of the moving assembly according to a detection result of the detector. The detector is arranged on an outer wall of the mobile body. The outer wall comprises the outer wall of the mobile body, which faces a direction of forward motion. The controller is arranged in the mobile body and is electrically connected to the detector. The detector is arranged on the outer wall of the mobile body so as to detect the ground undulation state, wherein the outer wall faces the direction of forward motion so that the motion state of the mobile body is controlled based on the undulation state, for instance, the mobile body is controlled to stop moving forwardly and circumambulate and so on. Therefore, a condition that the mobile body is toppled and fallen because of the undulation state is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an obstacle avoidance system. Background technique [0002] In recent years, with the development of robot technology and the deepening of artificial intelligence research, intelligent mobile robots have played an increasingly important role in human life, and have been widely used in fields such as welcoming and guiding. [0003] Intelligent mobile robot is a kind of robot system that can perceive the environment and its own state through sensors, and realize the goal-oriented autonomous navigation movement in the environment with obstacles, so as to complete the predetermined task. Therefore, the obstacle avoidance system is an essential element of intelligent mobile robots. Generally, obstacle avoidance is realized based on multiple obstacle avoidance sensors configured on an intelligent mobile robot to detect obstacles. [0004] However, for different intelligen...

AI Technical Summary

Problems solved by technology

[0005] The inventor has tested the walking state of a large number of mobile robots in different application environments and found that: for some intelligent mobile robots, it may be limited by the setting of its walking motion structure, and the unevenness of the ground will have different effects on its walking. Therefore, in order to prevent or cope with the situation where the intelligent mobile robot sinks into the ground with grooves or falls down the steps, it is necessary to provide an obstacle avoidance solution for this specific situation
