Abstract: Aiming at the problems of poor environmental performance, inflexible steering, low level of human-computer interaction and intelligent interconnection, large application scenario restrictions, and low work efficiency of traditional engine-driven lawn mowers, a new intelligent lawn mower that can be fully automated, realize automatic obstacle avoidance and intelligent alarm is proposed.It mainly includes external mechanical design, automatic obstacle avoidance function design, intelligent alarm function design, adaptive ramp mowing function design, drive scheme design and overall control logic design.Integrate traditional lawn mowing machinery with intelligent control technology and automation technology to explore the possible development direction of agricultural machinery in the future.
