Problems solved by technology

However, in the prior art, because the viewing angle of the sensor is generally small, configuring a single sensor on the intelligent mobile robot cannot satisfy the detection of obstacles in all directions, so the intelligent mobile robot is generally equipped with multiple sensors.
When multiple sensors deployed on the same intelligent mobile robot work at the same time, there may be mutual interference between different sensors. For example, the detection signal of one sensor is received by other sensors, which affects the accuracy of obstacle detection results.

Abstract

The embodiment of the invention provides a robot obstacle avoidance method and device. The method comprises the steps that N obstacle avoidance sensors arranged on a robot body is grouped by a processor according to the position relation, all the obstacle avoidance sensors belonging to different groups are enabled to work in the corresponding working times, and thus time-sharing working of the N obstacle avoidance sensors is achieved. Mutual interference of signals sent by the different sensors can be avoided through the time-sharing working mode of the N obstacle avoidance sensors, thus, the processor can receive detection data which are free of interference and are collected by the obstacle avoidance sensors with different working times, and obstacles are accurately identified by analyzing the detection data through the processor.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a robot obstacle avoidance method and device. Background technique [0002] In recent years, with the development of robotics 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 many fields such as welcoming guests. [0003] Intelligent mobile robot is a kind of robot system that can perceive the environment and its own state through detectors, and realize the goal-oriented autonomous navigation movement in the environment with obstacles, so as to complete the predetermined task. Therefore, the obstacle avoidance function is an essential element of intelligent mobile robots. [0004] Generally, obstacle avoidance is realized based on sensors configured on intelligent mobile robots to detect obstacles. However, in the prior art, because the viewi...
