Unitree R1-A5-D Smart B Humanoid Robot

Picture a robot colleague that rolls up to the workbench, raises itself to the height of the shelf and then reaches for what it needs with two arms. The Unitree R1-A5-D Smart B Humanoid Robot is built around that picture: a humanoid upper body that travels on wheels and adjusts its height with a lifting column, instead of walking on legs. For teams that care about handling objects, looking at them and learning from the result, that is a practical way to start.

The product is available through this page, by quotation.

Background

Unitree and the R1-A5-D line

Unitree Robotics is a name most robotics teams know from legged and humanoid platforms used in laboratories, classrooms and development projects. The R1 family extends that experience to dual-arm humanoids. Within it, the R1-A5-D variant adds a wheeled chassis and a lifting column, which takes the machine to 16 degrees of freedom. The family also includes R1-A5, R1-A7 and R1-A7-D versions, as well as several lettered Smart packages and an Ultimate B package on top of the R1-A5-D body.

The 16 degrees of freedom are counted as five single arms at two each, one waist joint, two head joints, one pillar joint and two base joints. In plain terms, the robot can turn its head, bend at the waist, reach with both arms, raise or lower its torso, and drive on its base. That is a lot of useful movement for a compact platform.

Where the Smart B package fits

The Smart B package sits among the lettered Smart configurations. What sets it apart is its hand and its computing: a Dex3-1 Hand with an RGB camera, and an Orin Nano module rated at 40 Tops, built in. The hand puts a camera right where the work happens, and the compute module gives developers processing power on board. Buyers who want a different mix can look at the sibling packages, such as the Unitree R1-A5-D Smart A Humanoid Robot or the Unitree R1-A5-D Smart C Humanoid Robot, and compare them with this one.

What makes the Smart B different from the base R1-A5-D?

The base machine, the Unitree R1-A5-D Mobile Base Dual-Arm Humanoid Robot, gives you the wheeled chassis, the lifting column and the dual-arm body. The Smart B keeps that body and adds the pieces that make it a working manipulation and perception platform out of the box: the Dex3-1 Hand with an RGB camera and the built-in Orin Nano with 40 Tops.

This matters because the hand and the compute module are usually the parts a team has to source, integrate and test on its own. With Smart B the choice is already made. The camera sits in the hand, so the view follows the grasp. Processing for vision and decision-making can run on the robot itself, next to the 8-core CPU in the body and the 8-core CPU with 10 TOPS in the head.

It is also worth looking at the other end of the range. The Unitree R1-A5-D Smart Ultimate F Humanoid Robot is listed separately, and buyers who want something beyond the Smart B package can compare it, along with the other lettered packages, before requesting a quotation.

How does the robot see and stay connected?

On the head, the robot carries a MID360 LiDAR and a stereo camera. Together with the RGB camera in the hand, this gives developers range data, stereo vision and a close-up view of the object being handled. The head moves through ±115° in yaw and ±36° in pitch, so the sensors can look around the workspace without the whole robot having to turn.

For connectivity, the robot supports Wi-Fi 6 and Bluetooth 5.2, and it supports smart OTA updates, so software can be refreshed without opening the machine. Localized air cooling keeps the electronics at a working temperature. Power comes from a removable lithium-ion battery in the chassis, with the running time listed in the table; being removable, the battery makes it possible to plan work in sessions.

Who is the Unitree R1-A5-D Smart B for?

University and institute laboratories are the most natural buyers. A dual-arm humanoid with a camera-equipped hand and onboard compute lets students and researchers work on grasping, perception and control without first building a robot. Education programs that want to show real humanoid hardware in a classroom will also find a machine that can raise itself to the height of a table.

Integrators and development teams make up the second group. They can use the Smart B as a testbed to try ideas before committing to a larger project, with a LiDAR, stereo camera and OTA updates already in place. Companies evaluating humanoids for demonstrations or pilot work belong here too.

Buyers who need a bare platform and plan to fit their own hand and computing can start with the base R1-A5-D. Those who want to see the whole range of the line can browse the Unitree R1-A5-D category or the wider Unitree R1 category.

What is the Unitree R1-A5-D Smart B used for?

1. Manipulation research: two arms and a dexterous hand with a camera give a base for studying grasping and handling.
2. Teaching robotics: a humanoid with a lifting column and wheeled base shows students how perception, planning and motion come together.
3. Perception and mapping work: the head-mounted LiDAR and stereo camera support experiments in sensing and navigation.
4. Onboard AI development: the built-in Orin Nano gives developers a place to run vision and learning workloads on the robot.
5. Human-robot interaction trials: a head that turns and arms that reach make the robot suitable for studying how people react to a humanoid.
6. Application prototyping: integrators can test a task or a workflow on the platform before planning a wider deployment.

Frequently Asked Questions

How many degrees of freedom does the Smart B have?

The R1-A5-D body has 16 degrees of freedom: five single arms at two each, one waist, two head joints, one pillar and two base joints.

Which hand does the Smart B use?

It uses the Dex3-1 Hand with an RGB camera, so the view is taken from the hand itself.

What computing is built in?

The Smart B has an Orin Nano rated at 40 Tops built in. The head adds an 8-core CPU with 10 TOPS, and the body has an 8-core CPU.

How long does the battery last?

The running time is approximately 1.5 hours on the removable lithium-ion battery in the chassis.

Does the robot connect wirelessly and receive updates?

Yes. It supports Wi-Fi 6 and Bluetooth 5.2, and it supports smart OTA updates.

What has the manufacturer not published?

The battery capacity, the IP rating, the maximum travel speed, the contents of the box, the payload of this exact configuration and the operating temperature. Ask us for them with your quotation.

Where can I buy the Unitree R1-A5-D Smart B Humanoid Robot and what does it cost?

You can buy it through this page, by quotation. The cost depends on the configuration, quantity and delivery place, so we send it with the quotation instead of printing it here.

Summary

The Unitree R1-A5-D Smart B Humanoid Robot answers a simple question: what if a humanoid could roll to the work and raise itself to the right height instead of walking? Its 16 degrees of freedom, wheeled chassis and lifting column do that, while the Dex3-1 Hand with an RGB camera, the Orin Nano with 40 Tops, the MID360 LiDAR and the head stereo camera give it the means to see and handle objects. For laboratories, classrooms and integrators who want that combination ready to use, this page is the starting point.
