Unitree MID360 LiDAR

The MID360 lidar reads the world through a rotating-mirror hybrid solid-state engine: a 905 nm laser swept across a full 360° horizontal circle and a 59° vertical arc, from -7° up to +52°. That upward bias is deliberate — the instrument sees over desks, shelves and kerbs while still covering the floor plane, which is exactly the geometry a robot needs for localisation. There is no large rotating head: the whole sensor measures 65 × 65 × 60 mm and weighs 265 g, small enough to sit on a Go2's back or inside an AS2's sensor pod without fighting for payload.

The numbers translate directly into map quality. 200,000 points per second at a 10 Hz frame rate gives roughly 40-line-equivalent density; the 0.1 m blind zone means floor clutter right in front of the robot is still measured; and ranging reaches 70 m on reflective targets outdoors, 40 m at 10% reflectivity. A built-in ICM-40609 IMU is fused with the point stream inside the unit, so LIO stacks get time-aligned motion data without a separate IMU board. Data leaves over 100BASE-TX Ethernet with PTPv2 or GPS sync, and Livox's SDK2 and ROS drivers cover the software side.

It is also built for robot duty rather than a lab bench: IP67 sealing, an operating range of -20 °C to +55 °C, and an active anti-interference mode that keeps the false alarm rate under 0.01% even in 100 klx sunlight or beside other laser sensors. The laser is Class 1 eye-safe, so the sensor can run around people without safety fencing.

On the Go2, the mid360 lidar is a catalogued accessory — the Go2-MID360 kit — and the same sensor ships from the factory on the Go2 EDU and Go2-W LiDAR configurations; Unitree's Go2-W developer documentation lists it as a supported SLAM sensor. One dependency to plan for: Unitree's own navigation algorithm on the Go2 runs on the expansion dock (100 Tops), so the dock belongs on the shopping list next to the sensor.

On the G1 the kit is sold with a purpose-shaped bracket, cable and frame under the G1-MID360L accessory number. The R1 and AS2 carry this same sensor as standard perception equipment from the factory — the R1 pairs it with a binocular camera, and the AS2 Edu LiDAR configurations list it with navigation-algorithm support — so the kit you receive matches the factory fit. The sensor was also offered for the earlier H1 and H1-2 platforms.

Every mid360 lidar kit is 100% quality-inspected before it ships, so it arrives in perfect working order. The sensor is a precision optical instrument: we ship it in rigid, shock-absorbing packaging with the optical window protected, and the IP67-sealed housing needs no maintenance beyond keeping that window clean and dry.

Store the sensor in its metal protective frame, avoid touching the optical window, and let any condensation dry at room temperature before powering it up. A spare battery for your robot travels in the same parcel if you are stocking up for a deployment.
