The yard robot is an autonomous mobile device designed for private outdoor spaces (such as lawns, pools, driveways, etc.), specializing in modular "1+N" operations including mowing, snow removal, cleaning, leaf blowing, and salt spreading. By integrating multiple sensors such as RTK, vision, and LiDAR, it achieves centimeter-level positioning, boundary recognition, and obstacle avoidance, enabling autonomous path planning and all-weather operation in complex terrains without the need for pre-buried boundary wires. The entire machine features IPX5–IPX6 waterproof rating, cold-resistant lithium batteries, and heated lens design, ensuring stable performance in rain, snow, low temperatures, and strong light conditions. Users can remotely set zones, cutting deck height, or snow removal angles via an app, and the robot can automatically return to recharge, resume interrupted tasks, and upload operation reports. With the popularity of "yard culture" in Europe and America and the declining cost of RTK modules, the penetration rate of robotic lawn mowers is rapidly increasing from 5%, making it the fastest-growing robotic category in household scenarios after robotic vacuum cleaners.
