Livox Mid-360

The cheapest way into real 3D LiDAR: 360° horizontal, -7° to +52° vertical, 40 m range, in a 265 g puck. Built-in IMU makes LIO pipelines much easier.

The role it plays

Sensors split into proprioception — encoders, IMUs, joint torque, motor current — which tells the robot about itself, and exteroception — LiDAR, depth, force, GNSS — which tells it about the world. Build proprioception first. A robot that does not know where its own joints are cannot use a good world model anyway.

Typical use: 3D SLAM, LIO, outdoor robots, drone mapping.

What the numbers actually mean

The headline figure is 40 m @ 10% reflectivity (range), with 360° H × 59° V (-7° to +52°) as the next most load-bearing number (fov). At $700 in the sensors tier it sits as a capital purchase. At this price you are buying documentation, repeatability and support as much as metal, and the integration cost is usually larger than the part.

GotchaNon-repetitive scan pattern means classic scan-matching needs a LIO pipeline (FAST-LIO2, Point-LIO), not a plain ICP.

How it compares

Same subsystem, closest alternatives. The primary spec column is usually the one that decides it.
