Method and system for walking robot to cross obstacle, and robot

Abstract

The invention discloses a method and system for a walking robot to cross an obstacle and a robot. The method for the walking robot to cross the obstacle includes detecting whether a first abnormal signal exists by a first detecting device and / or whether a second abnormal signal exists by a second detecting device during the walking of the robot; when only the first detecting device detects the first abnormal signal, detecting, by the first detecting device, a suspected obstacle to acquire first suspected obstacle information, and comparing the first suspected obstacle information with a firstcrossing distance value and / or a first rough surface threshold value in order to determine the type of the suspected obstacle; when the second detecting device detects the second abnormal signal, determining the type of the suspected obstacle. Compared with the prior art, the method for the walking robot to cross the obstacle can detect more obstacle types and responds based on the types by detecting and analyzing the obstacle.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a method for a robot to walk over obstacles, a system for a robot to walk over obstacles and a robot. Background technique [0002] For exploration robots, accurate recognition of obstacle types and realization of obstacle avoidance are the two most critical parts. To some extent, robot automatic obstacle avoidance can be regarded as a special case of robot route planning function, which has higher requirements for real-time and success rate (reliability) of products. [0003] At present, infrared sensors are mostly used to detect obstacles in the surrounding environment of robots, which realizes two-dimensional detection at a certain height. The obvious defect of this method is that the robot lacks information such as obstacles or ravines below the detection height. and the robot can judge fewer types of obstacles, and when encountering more complex obstacle information, the rob...
