Abstract
News editors obtained the following quote from the background information suppli ed by the inventors:“With the development of technologies, various smart robots have emerged, such as sweeping machines,mopping machines, vacuum cleaners, and lawnmowers. These robots can automatically identify the cleaningroute, and sel ect a cleaning mode according to the cleaning route, which saves labor and labor cost.“However, local shapes of most robots are unregular. For example, laser distance sensors (LDSs) arearranged at the top of some cleaning machines and protrude f rom the top cover plane of the cleaningmachine. During a walking process, when encountering a short obstacle (such as the bottom of a sofa andthe bottom of a piece of European style furniture) with unregular heights, the cleaning machine may betrapped at the short position of the obstacle.
