AI Technical Summary
Technical Problem
When existing mobile robots encounter obstacles, residual obstacle information caused by sensor noise and observation instability affects the accuracy and safety of obstacle avoidance decisions.
Method used
By performing a Hough transform on sensor observation data, obstacles are identified and added to the obstacle list. An initial state and recording time are set, and the obstacle state is maintained in combination with a preset time threshold to optimize obstacle avoidance decisions.
Benefits of technology
It reduces the impact of sensor noise on obstacle avoidance decisions, avoids residual obstacle information, and improves the rationality and safety of obstacle avoidance.

Abstract
The application provides a method and device for mobile robots to deal with obstacles. The method comprises: obtaining observation data, and performing Hough transform on the observation data to obtain a corresponding Hough transform result; determining an obstacle in an environment in which the mobile robot is located based on the Hough transform result and a preset parameter; setting an initial state of the obstacle and recording a setting time, and adding the obstacle, the initial state of the obstacle and the setting time to an obstacle list; maintaining a current state of the corresponding obstacle in the obstacle list based on the setting time and a preset time threshold, and determining whether to include the obstacle in an obstacle avoidance decision according to the current state of the obstacle in the obstacle list. Through the method, the observation data can be "remembered", noise caused by observation instability can be reduced, and insufficient obstacle information can be avoided, so that the obstacle avoidance decision is more reasonable, safe and reliable.
