Unitree R1-A7 Smart B Humanoid Robot

Most robot platforms arrive as a list of decisions you still have to make: which hands, which compute, which add-ons. The Unitree R1-A7 Smart B Humanoid Robot arrives with two of those decisions already made. It carries Dex3-1 hands, and the Smart configuration adds an Orin Nano module rated at 40 TOPS, so a team can start from a defined working setup instead of a blank bench.

Background

The company and the R1 line

Unitree Robotics is a manufacturer known for legged and humanoid robots, and for building platforms that universities, laboratories and integrators can program themselves. The R1 family follows that approach. The fact sheet for this product names seven versions: R1-A5, R1-A7, R1-A5-D, R1-A7-D, R1-A7 Smart A, R1-A7 Smart B and R1-A7 Smart C. The base R1-A7 sets the mechanical and sensing figures, and the Smart versions build on it with different hands and added computing.

That lineage matters when you read a specification sheet. The dimensions, weight, battery figure and joint motor in the table below are stated for the R1-A7. The Smart B differs from that base in the two ways the fact sheet records: its Dex3-1 hands and its added Orin Nano compute. Nothing else is assumed to change, and nothing is borrowed from a sibling.

Positioning and key technology

The R1-A7 platform is built around a low-inertia, high-speed inner rotor PMSM joint motor, which the manufacturer describes as offering superior responsiveness and heat dissipation. In practical terms, that is the part of a humanoid that decides how quickly and how smoothly it can follow a command.

For perception, the head holds an 8-core high-performance CPU with 10 TOPS, a binocular camera and a four-array microphone with dual speakers. Open interfaces cover the underlying system, the robotic arm, audio, lighting and visual control. On the Smart B, the added Orin Nano brings 40 TOPS of further computing for heavier perception and decision-making workloads, while Dex3-1 hands handle the manipulation end of the job.

Technical Specifications

The manufacturer has not published the IP rating, the operating temperature range, the top speed or the weight of the Smart B with its hands fitted; these are confirmed at quotation.

What does the Smart B add to the base R1-A7?

The base R1-A7 already has a capable head: an 8-core CPU with 10 TOPS, a binocular camera and a microphone array. That is enough for many basic interaction and vision tasks. The Smart configurations go further by adding a 40 TOPS Orin Nano, which gives a team considerably more room to run perception models and decision logic on the robot itself.

The second difference is the hands. The Smart B is specified with Dex3-1 Hands. The base R1-A7 lists a choice of end effectors, from a two-finger gripper to a three-finger or five-finger dexterous hand, so the Smart B settles that choice for you. If you want to see how other Smart packages differ, the Unitree R1-A7 Smart A Humanoid Robot and the Unitree R1-A7 Smart C Humanoid Robot are the neighboring configurations. For the platform without the Smart additions, see the Unitree R1-A7 Fixed Base Dual-Arm Humanoid Robot.

Is the Smart B ready to extend with more computing?

The fact sheet lists a high-computing module, such as an Orin in the 40 to 100 TOPS range, as part of the platform, and it states that the interfaces are open for the underlying system, the arm, audio, lighting and visual control. In plain terms, the robot is meant to be programmed and extended, not used only as a sealed demonstration unit.

What the sources do not say is exactly which compute module is paired with which package beyond the 40 TOPS Orin Nano named for Smart configurations. If your project depends on a specific module, raise it when you request a quotation so it can be confirmed in writing.

Who is the Unitree R1-A7 Smart B for?

University and laboratory teams are the clearest fit. They need a robot that can see, hear, move and handle objects, and they need open interfaces to put their own software on it. The Dex3-1 hands and the added compute make the Smart B a sensible choice where manipulation research and on-board perception go together.

Educators setting up a robotics program will find the same strengths useful, since students can work with vision, audio and arm control on one platform. System integrators can use it to evaluate a humanoid for a pilot before committing to a larger deployment. Technical buyers who want a different hand arrangement may prefer to compare the Smart A or the Smart C, and the wider Unitree R1-A7 category shows the full set of options.

Buyers who need a documented IP rating, a temperature range or a top speed should know those figures are not published; they should be requested before any outdoor or demanding deployment is planned.

What is the Unitree R1-A7 Smart B used for?

1. Manipulation research: Dex3-1 hands let teams study grasping and handling tasks on a humanoid platform.
2. On-board perception work: The added 40 TOPS Orin Nano supports vision and decision models running on the robot.
3. Teaching and training: Students can work with cameras, microphones, speakers and arm control in one system.
4. Human-robot interaction trials: The four-array microphone and dual speakers support voice-based experiments.
5. Software development: Open interfaces for the arm, audio, lighting and visual control let developers write their own control layers.
6. Integration pilots: Integrators can evaluate a humanoid in a real workflow before planning wider use.

Frequently Asked Questions

What hands does the Smart B use?

The R1-A7 Smart B is specified with Dex3-1 Hands. The base R1-A7 lists separate optional end effectors, which are a different matter.

How much computing power does it have?

The head of the R1-A7 carries an 8-core high-performance CPU with 10 TOPS. Smart configurations add a 40 TOPS Orin Nano.

How long does the battery last?

The R1-A7 is listed at approximately 1.5h when battery-powered. The figure is given for the R1-A7, and the Smart B with its hands is not separately stated.

What can the cameras and microphones do?

The binocular camera provides RGB at 1280×720@30Hz, with a horizontal field of view of 146° and a vertical field of view of 124°. Audio comes from a 4-array microphone and dual speakers.

Is a charger included?

Yes, the fact sheet states that a charger is included.

Can I program the robot myself?

Open interfaces are listed for the underlying system, the robotic arm, audio, lighting and visual control, which is what makes custom development possible.

Where can I buy the Unitree R1-A7 Smart B Humanoid Robot and what does it cost?

You can request it through this page, by quotation. We do not print prices; the quotation sets out the configuration, delivery and support for your order.

Summary

The appeal of the Unitree R1-A7 Smart B Humanoid Robot is that the early decisions are already made. You get Dex3-1 hands, a 40 TOPS Orin Nano on top of the 10 TOPS head, a binocular camera, a four-array microphone and open interfaces, on a platform built around a responsive PMSM joint motor. What remains is your own work: the software, the experiments and the application. For a quotation tailored to that work, this page is the starting point.
