Embodiment Construction

[0058] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0059] Overview of the prior art

[0060] The existing obstacle avoidance methods for vacuum cleaners mainly include precise obstacle avoidance and fuzzy obstacle avoidance. "Path Planning for Mobile Robots" (Master's Thesis of Northeast Electric Power University, Meng Xiangfu) discloses the method of fuzzy obstacle avoidance, which adopts fuzzy logic algorithm, which has a large amount of system calculation and is not suitable for low-cost vacuuming robots. However, "Design of Hybrid Perception System and Obstacle Avoidance Planning for Autonomous Vacuuming Robot Based on Jiren Neural Network" (Master's Thesis of Zhejiang University, Xu Yong) discloses an intelligent obstacle avoidance algorithm for vacuuming robots based on neural network. The algorithm is not per...
