Unitree R1-A7 Smart B Humanoid Robot

A robot that can take in most of a room at a glance but cannot close its fingers around what it sees remains an observer. The Unitree R1-A7 Smart B Humanoid Robot is configured to close that gap. Its binocular camera covers a horizontal field of view of 146° and a vertical field of view of 124°, a four-microphone array listens for spoken instructions, and Dex3-1 Hands are fitted to its arms, so what the robot perceives can become something it grips, moves and places. Behind the sensors, the Smart configuration adds a 40 TOPS Orin Nano to the computing already housed in the head, giving perception and manipulation software room to run on the robot itself.

Robots Middle East sells the Unitree R1-A7 Smart B Humanoid Robot to universities, research institutes, system integrators and corporate innovation teams throughout the Middle East. We prepare each quotation for the exact configuration requested, arrange delivery and customs clearance to the destination country, and remain your point of contact for technical support once the robot is in service.

Background

Unitree Robotics and its route to humanoids

Unitree Robotics, based in Hangzhou, China, first became widely known for its quadruped robots, which found their way into research laboratories, inspection projects and education. The company then extended its engineering in compact actuators, motion control and onboard computing into humanoid platforms. The R1 family continues that trajectory: rather than offering a single fixed product, Unitree offers a set of versions and configurations so that buyers can choose the arms, hands and computing that suit their programme of work.

The R1-A7 platform and the Smart B configuration

The R1 family includes several versions, among them the R1-A5, the R1-A7, the R1-A5-D and the R1-A7-D, together with the Smart A, Smart B and Smart C configurations of the R1-A7. The R1-A7 itself accepts a choice of end effectors: a two-finger gripper, a three-finger dexterous hand or a five-finger dexterous hand. The Smart B configuration settles that choice by specifying Dex3-1 Hands, and, as with the other Smart configurations, it adds a 40 TOPS Orin Nano module. The result is a defined starting point: a platform whose hands and additional computing are agreed from the outset, which simplifies both procurement and the planning of software work.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

Unitree 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 points are confirmed with you at quotation.

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

Two things distinguish the Smart B from the plain R1-A7: the hands and the computing. On the base platform, the end effector is an open decision between a two-finger gripper, a three-finger dexterous hand and a five-finger dexterous hand. The Smart B removes that decision by specifying Dex3-1 Hands, which means the configuration you evaluate is the configuration you receive, and the grasping work your team plans can be written around a known piece of hardware.

The second addition is the 40 TOPS Orin Nano. The R1-A7 already carries an 8-core high-performance CPU with 10 TOPS in its head, which handles the robot's own operation. The Smart configurations place a further module alongside it, giving developers dedicated capacity for vision models, speech processing or learned manipulation policies without first designing their own computing payload. For teams whose workloads grow beyond that, the platform also lists high-computing modules such as Orin in the 40-100TOPS range.

The joints themselves use low-inertia, high-speed inner rotor permanent magnet synchronous motors, chosen by Unitree for responsiveness and heat dissipation. For dexterous work, responsive joints matter: a hand can only place an object accurately if the arm carrying it settles quickly and predictably.

How does the R1-A7 Smart B perceive and interact with people?

Perception begins with the binocular camera, which delivers RGB images at 1280×720@30Hz across a field of view of 146° horizontally and 124° vertically. A wide view of that kind lets the robot keep a workbench, a pair of hands and a person in front of it within the same frame, which is useful both for manipulation research and for interaction studies.

Sound is handled by a 4-array microphone with dual speakers, so the robot can capture spoken commands and reply audibly. Combined with lighting and visual control, both exposed through open interfaces, this gives developers the elements of a complete interaction loop: the robot can hear a request, locate the relevant object, act on it with its Dex3-1 Hands and confirm what it has done.

Those open interfaces extend to the underlying system and the robotic arm, which is what makes the platform suitable for development rather than demonstration alone. Teams can connect their own software stacks, run experiments of their own design and integrate the robot with other equipment in their facility. The R1-A7 runs from an external power supply or on its battery, which lasts approximately 1.5h, and a charger is included.

Who is the Unitree R1-A7 Smart B Humanoid Robot for?

The Smart B suits university laboratories working on dexterous manipulation, embodied artificial intelligence and human-robot interaction, where a defined hand and onboard computing let several research groups share a common platform. It equally suits engineering faculties that wish to teach robotics with hardware students can program directly through open interfaces.

System integrators and corporate innovation teams will find it a practical vehicle for prototyping service and handling applications, and for presenting concepts to stakeholders before committing to larger projects. Technology centres and exhibition spaces may also value the combination of speech, vision and hands for interactive demonstrations.

Buyers who would rather select their own end effector, such as the two-finger gripper or the five-finger dexterous hand, may prefer to start from the Unitree R1-A7 Fixed Base Dual-Arm Humanoid Robot. Those comparing packaged configurations can review the Unitree R1-A7 Smart A Humanoid Robot and the Unitree R1-A7 Smart C Humanoid Robot, and the full range is gathered in the Unitree R1-A7 category. Our team will gladly help you decide which configuration matches your objectives.

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

Summary

Seeing is only half of useful work; the other half is acting on what has been seen. The Unitree R1-A7 Smart B Humanoid Robot brings the two together in one defined configuration: a wide-view binocular camera and a four-microphone array to perceive, Dex3-1 Hands to manipulate, and a 40 TOPS Orin Nano alongside the head's own computing to connect the two. Open interfaces turn that combination into a platform for research, teaching and prototyping rather than a closed demonstration. Robots Middle East quotes, delivers and supports it throughout the region, and for any team ready to move its robots from observing to doing, this page is the starting point.
