The Z-Star is a foldable autonomous unmanned cleaning boat from Future Axis, designed for water surface waste collection in urban rivers, reservoirs, lakes, and ports. It features a smart dual-jointed robotic arm with a maximum collection span of 4 meters, LiDAR and 4D millimeter-wave radar with 3D SLAM for centimeter-level mapping, and Level 4 fully autonomous operation. It can automatically return to a smart waste station for debris unloading and docking for charging, reducing cleaning costs by approximately 75 percent compared to manual methods.
