Instead of relying on a physical boundary wire or just an RTK antenna, the Tri-Fusion system combines three technologies to maintain its position as it mows your lawn: LiDAR, NetRTK, and AI for visual recognition. The robot captures a large LiDAR field of full 360 degrees horizontally and 59 degrees vertically, with a range of up to 330 feet. This generates a live 3D map composed of millions of data points, ensuring the robot detects obstacles within one centimeter and adjusts its course accordingly.
