Unitree G1 Mid360 Lidar (G1-MID360L)

G1 Mid360 Lidar G1 Series Accessories (G1-Mid360L) (G1-MID360L)

LiDAR (Light Detection and Ranging) sensors generate three-dimensional point clouds by measuring distances to surfaces using laser pulses. On humanoid robots such as the Unitree G1, a 3D LiDAR is typically used for SLAM (Simultaneous Localization and Mapping), autonomous navigation, collision avoidance, and stable movement in complex indoor and outdoor environments. Unitree’s developer documentation indicates that the G1 head is equipped with a LIVOX-MID360 laser radar, highlighting the MID-360’s role in the G1 perception stack.

As a product listing, G1-MID360L is commonly sold as a dedicated unit for the Unitree G1 ecosystem and may be provided with mounting hardware and cabling for integration.

Design and Features

360° situational awareness for humanoid navigation

The Livox MID-360 is designed for omnidirectional horizontal scanning and wide vertical coverage. Official specifications list a 360° horizontal field of view and vertical coverage from -7° to 52°, often summarized as a 59° vertical FOV.
For humanoid robots, this wide coverage is valuable when stepping around obstacles, navigating cluttered hallways, and detecting hazards at multiple heights (floor clutter, table edges, shelving, and partial occlusions).

Compact form factor for head or torso mounting

The MID-360 is positioned as a small, lightweight LiDAR suitable for space-constrained platforms. Official specs list a body size around 65 × 65 × 60 mm and a weight of ~265 g, supporting integration on humanoid heads or upper body frames without excessive inertia.

Robotics-friendly connectivity and synchronization

For real-time autonomy, LiDAR data must be delivered with low latency and consistent timing. The MID-360 provides 100BASE-TX Ethernet for data output and supports synchronization features listed by the manufacturer.
Ethernet connectivity is a common choice in robotics stacks because it enables reliable point cloud streaming and integration with compute modules running ROS/ROS2 pipelines.

Unitree-focused integration package (mounting and cabling)

Listings for Unitree-branded MID360 packages often mention inclusion of mount/rack hardware and customized cables, plus protective mounting structures for field use.
This type of integration bundle can reduce setup friction compared with sourcing a standalone sensor and designing mounts from scratch.

Technology and Specifications

Core LiDAR specifications (Livox MID-360 reference)

The G1-MID360L is associated with the Livox MID-360 sensor family, with key published specifications including:

• Laser wavelength: 905 nm

• Laser safety: Class 1 (IEC 60825-1:2014)

• Detection range (100 klx):

  • 40 m @ 10% reflectivity

  • 70 m @ 80% reflectivity

• Close proximity blind zone: 0.1 m

• FOV: 360° horizontal, -7° to 52° vertical

• Point rate: 200,000 points/s (first return)

• Frame rate: 10 Hz (typical)

• Range precision (1σ): ≤2 cm (@10 m), ≤3 cm (@0.2 m)

• Angular precision (1σ): <0.15°

• Data port: 100BASE-TX Ethernet

These parameters make MID-360 a “high-density, short-to-mid-range” LiDAR suitable for navigation and mapping in many robotics deployments.

Fit for the Unitree G1 perception stack

Unitree’s documentation explicitly links the G1 head to the LIVOX-MID360 LiDAR, suggesting the platform is designed to leverage this sensor for environmental perception.
In practical deployments, MID-360 data is commonly fused with other sensors (vision, IMU, encoders) to produce robust localization and obstacle models.

Applications and Use Cases

1) Autonomous navigation and humanoid mobility

A humanoid robot’s greatest operational risk is collisions and unstable steps caused by incomplete perception. A 360° LiDAR supports:

• detecting obstacles around the robot during turning and sidestepping

• mapping hallways and rooms for repeatable routes

• identifying near-field hazards (blind-zone permitting)

• assisting step planning by providing geometry of nearby structures

The MID-360’s high point rate helps maintain situational awareness while the robot moves.

2) SLAM mapping for indoor environments

A major reason to choose LiDAR on a mobile robot is stable 3D mapping in environments where lighting changes or reflective surfaces challenge cameras. With MID-360, the G1 can generate point clouds used for:

• building local occupancy maps

• loop closure and localization refinement

• scan matching in long corridors or repeated rooms

• creating reference maps for demonstrations and research

3) Inspection, patrol, and security research workflows

When paired with a humanoid platform, LiDAR can support navigation for patrol behaviors such as:

• autonomous hallway traversal

• waypoint-based inspection routes

• obstacle-robust movement in partially unknown spaces

• consistent re-visiting of checkpoints

This is especially relevant for labs testing human-scale autonomous operations.

4) Robotics R&D and dataset generation

For robotics teams and universities, G1-MID360L can be used to collect real-world point clouds for:

• perception research (clustering, segmentation, tracking)

• learning-based navigation policies

• sensor fusion experiments (LiDAR + vision)

• benchmarking SLAM performance under motion and clutter

Advantages / Benefits

True 360° horizontal scanning for safer movement

A full 360° horizontal LiDAR view reduces blind spots during turns and side movements, which is helpful for humanoids that frequently rotate in place.

High point rate for real-time autonomy

A published 200,000 points/s stream supports dense perception compared with many low-channel sensors, improving obstacle definition and map stability.

Compact and lightweight integration

At roughly 265 g and a small enclosure, the MID-360 is suited to mobile robots where payload and inertia matter.

Industry-standard Ethernet connectivity

Using 100BASE-TX Ethernet simplifies integration with robotics compute systems and ROS networking patterns.
