Unitree H2-A Standard I Humanoid Robot

Most of a humanoid's strength is spent just staying upright. The Unitree H2-A Standard I Humanoid Robot is built around that fact: its leg joints are rated for three times the torque of its arm joints, because the legs carry the whole machine while the arms do the work. That split tells you a good deal about how this robot is meant to be used.

The Unitree H2-A Standard I Humanoid Robot is available through this page, by quotation.

Background

Unitree Robotics and its lineage

Unitree Robotics is known for compact, high-torque joint actuators, first proven in quadruped robots and later carried into bipedal humanoids. That actuator experience matters in a humanoid. Every joint has to be strong, light and quick to respond, and the same design thinking runs through the H2 family. Labs, universities and integrators across the world use Unitree platforms for research, teaching and applied robotics work.

The H2 sits in the full-size part of that range. It is a humanoid with a bionic head and facial features, and a body made for walking, reaching and carrying. The fact sheet for this page names three versions of the platform: H2, H2 EDU and H2 Plus. This page covers the Standard I configuration, and the figures below are those of the H2 platform.

Positioning and key technology

The H2 is designed at 180 cm, a human scale that suits human spaces. Its structure combines aircraft-grade aluminum, titanium alloy and high-strength engineering plastics. This keeps the frame rigid where loads are high and light where they are not.

The platform has 31 degrees of freedom in total. Each leg has 6 and each arm has 7. The seven-axis arm is the more important number for manipulation work, because an extra axis lets the arm approach an object from several angles and work around obstacles. For sensing, the robot has a humanoid binocular camera with a wide field of view. For interaction, it has an array microphone and a high-power speaker.

Why do the leg and arm torque figures differ so much?

The leg joint is specified at 360N.m and the arm joint at 120N.m. The difference follows from the job each limb does. In a walking robot, the hips and knees carry the full weight of the body, and they absorb impact with every step. They also have to recover balance. A leg that is too weak cannot hold the body up or catch a stumble. The arms carry only what they pick up, plus their own weight.

The arm figures are worth reading closely. The maximum payload is a peak of about 15 kg and a rated load of about 7 kg. The rated figure is the one to use when planning a repeated task. The peak figure describes what the arm can manage briefly. Anyone designing a handling job should plan around the rated load and treat the peak as headroom.

Weight is the other half of the picture. At about 70kg with the battery fitted, the robot is a serious machine that needs sensible handling, a clear working area and trained operators. At the same time, the high-torque joints are what allow a body of this size to move with purpose rather than shuffle.

How does the battery shape daily use?

The battery is 15Ah (0.972KWh), and the platform runs for about 3h. The smart battery has a quick-release design, and a charger comes with the robot. Quick release makes a practical difference. A pack can be removed and replaced without long teardown, which helps in a teaching lab or a demonstration schedule.

If your use needs long continuous operation, tell us when you request a quotation and we will help you plan a charging routine around your working day.

Who is the Unitree H2-A Standard I Humanoid Robot for?

University and research groups come first. A full-size humanoid with a seven-axis arm, a binocular camera and a voice system gives students and researchers a platform for studying locomotion, manipulation, perception and human-robot interaction on real hardware.

System integrators and engineering teams are the second group. They can use the robot to test whether a humanoid form fits a process designed around human workspaces, before they commit to a wider deployment.

Exhibition, visitor-center and reception teams are the third. The bionic head with facial features, the array microphone and the speaker make the robot suited to public-facing roles where people speak to the machine.

Buyers who need dexterous hands should note that they are not listed for the base H2, while the H2 EDU is listed with several hand options. If your work depends on fine finger manipulation, raise it with us when you request a quotation. You can also compare sibling configurations such as the Unitree H2-A Standard A Humanoid Robot, the Unitree H2-A Standard B Humanoid Robot or the Unitree H2-A Standard C Humanoid Robot.

What is the Unitree H2-A Standard I Humanoid Robot used for?

1. Locomotion research. Six degrees of freedom per leg and high leg-joint torque give teams a full-size bipedal platform for gait and balance study.
2. Manipulation experiments. Seven-axis arms with a rated payload of about 7 kg support reaching, lifting and handling trials.
3. Teaching and training. Students work on a real humanoid instead of a simulation alone, which makes robotics courses more concrete.
4. Human-robot interaction. The array microphone, high-power speaker and bionic head with facial features suit voice and presence studies.
5. Perception development. The wide-field binocular camera gives vision researchers a human-like viewpoint for mapping and recognition work.
6. Demonstration and display. A 180 cm humanoid draws attention at exhibitions, visitor centers and corporate events.
