What You’ll Need: Tools, Space & Time

The Unitree H2 is a full‑size humanoid (182 cm tall, 70 kg, 31 DOF) that requires careful preparation. Before starting, gather:

• Supplies: the robot itself, its charger, an Ethernet cable, a laptop with Ubuntu 20.04 (or 22.04 for later SDK versions), a suspension rig or sturdy stand capable of supporting 70 kg, and a non‑slip rubber mat.
• Space: minimum 3,5 m × 3,5 m of clear flat floor; ideally 4 m × 4 m for first walks.
• Time estimates (first‑timer):

Before You Start: Safety & Space Requirements

Step 1 — Unboxing & Physical Inspection

1. Open the shipping case with the robot lying face‑up. Check for any visible transport damage.
2. Verify that all accessories are present: charger, controller, cables, initial‑setup guide.
3. Visually inspect the 7‑DOF arms, bionic head, and all 31 joints for loose fasteners.
4. Photograph the robot’s condition before first power — this helps with warranty claims.
5. Position the robot on its suspension rig, with the feet hovering just above the floor.

Step 2 — Battery Installation & Charging

The H2 uses an internal, non‑swappable 54 V battery pack (approximately 3 hr runtime).

• Plug the supplied 54 V/5 A charger into the charging port on the robot’s back.
• A full charge takes up to 2 hours. The battery indicator on the robot’s power panel will turn solid green when complete.
• Charge the battery fully before first power‑on; partial charge can cause a premature shutdown during calibration.

Step 3 — Powering On & First Boot

1. Ensure the robot is still suspended and the floor is clear.
2. Press and hold the main power button for 3 seconds.
3. Watch the boot sequence: the head’s facial display will light up, and the fans will spin up. The robot will emit a series of beeps.
4. After about 60 seconds, the system reaches a stable idle state.
5. Do not attempt to stand until calibration (Step 8).

Step 4 — Network Configuration (WiFi vs Ethernet)

The H2’s onboard control computer runs on the 192.168.123.x/24 subnet. For development and SDK access, a wired Ethernet connection is strongly preferred over WiFi.

• Identify the robot’s IP address — the onboard computer (likely a Jetson Orin) typically uses 192.168.123.164. The control board may be at 192.168.123.161.
• Set your laptop’s Ethernet interface to a static IP such as 192.168.123.99 (subnet mask 255.255.255.0, no gateway).
• Connect the Ethernet cable directly between your laptop and the robot’s LAN port.
• Verify connectivity: ping 192.168.123.164 should succeed.
• [Optional] If you need wireless, connect the robot to your home WiFi via the companion app (Step 5). Always revert to wired for SDK work due to lower latency.

Step 5 — App / Remote Control Binding

1. Install the Unitree Controller app on your smartphone or tablet (Android recommended).
2. Power on the robot; the app will scan for nearby Unitree devices on the same WiFi network or via Bluetooth.
3. Select the H2 from the device list and follow the on‑screen binding code.
4. Once bound, the physical remote controller will also be paired automatically.
5. Test basic damping by pressing L2+B — the motors should go limp, and the robot will sag slightly in the rig.

Step 6 — Firmware Update & Security Hardening

> Important: All Unitree robots (Go2, G1, H1, H2) are affected by the UniPwn vulnerability (CVE‑2025‑35027) — a wormable BLE‑to‑root chain. Always apply firmware updates and disable unnecessary wireless services.

1. Check the current firmware version via the app or by SSH (unitree@, default password 123 — change this immediately).
2. Download the latest firmware from the official Unitree support portal. As of publication, the H2 is a pre‑production unit; firmware images are provided to early access partners.
3. Apply the update using the app’s OTA function or manually via USB. Reboot.
4. After update, disable BLE provisioning if you won’t be using the setup wizard again (app settings → disable “BLE broadcast”).
5. Segment your robot’s network — place it on a separate VLAN from your main home devices.
6. Change all default credentials (SSH, app, web console).

Step 7 — SDK / ROS2 Setup (Advanced)

The Unitree H2 runs the same unitree_sdk2 / unitree_sdk2_python stack as the G1 and H1, built on CycloneDDS. For custom code or ROS2 integration:

Prerequisites: Ubuntu 20.04 LTS (or 22.04 if supported by later SDK releases).

# 1. Install CycloneDDS (version 0.10.2, releases/0.10.x branch)
git clone https://github.com/eclipse-cyclonedds/cyclonedds -b releases/0.10.x
cd cyclonedds && mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/opt/cyclonedds
make -j$(nproc) && sudo make install

# 2. Set environment variables
export CYCLONEDDS_HOME=/opt/cyclonedds
export LD_LIBRARY_PATH=$CYCLONEDDS_HOME/lib:$LD_LIBRARY_PATH

# 3. Clone and build unitree_sdk2
git clone https://github.com/unitreerobotics/unitree_sdk2
cd unitree_sdk2 && mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/opt/unitree_robotics
make -j$(nproc) && sudo make install

For Python:

git clone https://github.com/unitreerobotics/unitree_sdk2_python
cd unitree_sdk2_python
pip3 install -e .

ROS2 (Foxy) support with unitree_ros2:

git clone https://github.com/unitreerobotics/unitree_ros2
# Follow the repository’s README for colcon build

Verify with the example_walk demo after network setup. Ensure that the AI sport client is active (not debug mode) when using high‑level RPC commands.

Step 8 — Calibration & First Movement

1. With the robot still suspended, start the calibration routine from the app: Settings → Calibration → Full Body.
2. The robot will move each joint through its range. This takes about 3–5 minutes.
3. After calibration, the damping mode (L2+B) will be fully active. Release damping to let the motors stiffen.
4. Lower the robot slowly with the rig until its feet touch the ground, but keep the rig taut for balance.
5. Press L2+UP (ready pose), then R2+A to gently initiate a standing posture. The robot will slowly rise.
6. For first steps, use the remote to jog the robot forward at low speed (≤0.5 m/s). Stay within the exclusion zone with the e‑stop ready.
