Updated 2026-10-26 · YUANZHI ROBOTICS engineering team
A ready-to-order sensor payload for the Unitree B2: 3D LiDAR, dual-spectrum (visible + thermal) gimbal, depth camera, dual-antenna RTK GNSS and 5G, assembled on a sealed aluminium back shell on the B2 top mounting interface and tested before shipping.
What is in the kit
| Mount | A sealed aluminium back shell on the B2 top mounting interface |
| 3D LiDAR | Livox Mid-360 (360° × 59° FOV, about 265 g, 6.5 W) |
| Dual-spectrum gimbal | Hikvision HM-TD5737T-4/W robot micro gimbal: 384 × 288 thermal + 2688 × 1520 visible, pan and tilt, about 2.0 kg, up to 20 W |
| Depth camera | Intel RealSense D435i with IMU, for obstacle detection |
| RTK GNSS | Unicore UM982 dual-antenna board with two helical antennas (position and heading) |
| 5G module | Industrial 5G module with antennas for remote video and teleoperation |
| Power and network | DC-DC converter, power distribution board, Gigabit Ethernet switch, cable glands |
Specifications
| Compatible robot | Unitree B2 (robot not included; rated payload 40 kg) |
| Kit weight | about 4.4 kg including mount and cabling |
| Peak power | about 72 W with all devices active |
| Power source | The B2 payload power output through a DC-DC converter |
| Data | Ethernet to the robot network; RTSP video, ISAPI gimbal control, Livox and RealSense ROS 2 drivers |
| Software | ROS 2 bring-up for all sensors on Ubuntu; works with your existing onboard computer or our optional Jetson Orin NX |
| Lead time | 4 to 6 weeks after payment |
| Warranty | 12 months on the kit hardware |
How it fits the B2
The kit mounts on a sealed aluminium back shell on the B2 top mounting interface and is powered from the B2 payload power output through a DC-DC converter. The B2 carries up to about 40 kg, so this kit uses a small fraction of its capacity and leaves room for gas sensors, a speaker or a manipulator later. All devices connect to one Ethernet switch inside the payload, so the robot computer sees the LiDAR, gimbal and GNSS on one network.
Options
- Onboard computer: NVIDIA Jetson Orin NX 16GB with ROS 2 pre-installed, +US$2,290
- Lighter build: remove the 5G module, RTK or depth camera to save weight and cost (quoted on request)
- Software: autonomous inspection routes, gauge reading, thermal alarms, mapping and navigation are available as custom development
- Colour and branding: shell colour and logo to your specification
Price and delivery terms
- The price covers the payload kit only. The Unitree B2 itself is not included.
- Prices are in US dollars, ex-works China. We quote freight to your door (DAP) for your country; import duty and VAT are paid by the buyer.
- Payment in advance by bank transfer. Lead time 4–6 weeks after payment.
- 12-month hardware warranty and remote technical support in English.
- Built for research, development and pilot projects. The assembled kit does not carry CE marking or a tested IP rating; component ratings are listed by their manufacturers.

FAQ
How much does an inspection payload for the Unitree B2 cost?
The YUANZHI Unitree B2 inspection payload kit starts at US$9,090 for the kit only (LiDAR, dual-spectrum gimbal, depth camera, RTK GNSS, 5G, mount and power). The robot, shipping and import duty are not included; an onboard Jetson Orin NX adds US$2,290.
Is the Unitree B2 included?
No. The kit is designed for a Unitree B2 you already own or buy separately. We can advise on where to buy the robot in your country.
How long does delivery take?
Assembly and testing take 4 to 6 weeks after payment, then shipping by air or express, usually 5 to 10 days to Europe or North America.
Does it work with ROS 2?
Yes. All sensors are delivered with ROS 2 drivers configured, and the kit connects to the robot over Ethernet, so it works with your existing onboard computer.
Can the configuration be changed?
Yes. Sensors can be removed or swapped (for example a different LiDAR, a gas detector or a speaker), and we quote the changed kit within one working day.
