This paper aims to design an ice and snow removal robot in view of the potential safety hazards to pedestrians caused by ice and snow compaction on sidewalks in winter in northern areas, as well as the large labor and low efficiency of clearing ice and snow. Inspired by the ultrasonic extracorporeal lithotripsy, I created a new concept of ultrasonic removal and compaction of ice and snow that "Breaking the ice first, and then cleaning up", and designed a small ultrasonic cleaning and compaction robot using ultrasonic technology to break, push and remove ice and snow, and simulated experiments on ice breaking devices to explore its effects. Through the simulation experiment of the ultrasonic ice breaking mechanism, the robot has remarkable ice breaking, convenient operation and flexible action. It is suitable for clearing and compacting ice and snow on the sidewalk, and has promotion value.
