Unitree R1-A5-D Smart B Humanoid Robot

Most of what a humanoid robot knows about the world arrives through its head, some distance from the object its fingers are trying to close around. The Unitree R1-A5-D Smart B Humanoid Robot narrows that gap. Its head carries a MID360 LiDAR and a stereo camera for the wide view, while the Smart B package fits a Dex3-1 Hand (with RGB Camera), so the last moments of a grasp can be observed from the hand itself. Add a wheeled chassis, a lifting column and a built-in Orin Nano module, and the result is a platform designed to survey a scene, approach it and handle what it finds with one integrated body.

Robots Middle East supplies the Unitree R1-A5-D Smart B Humanoid Robot to universities, research centres, innovation laboratories and system integrators across the Middle East. Our team prepares each quotation for the exact configuration you request, arranges delivery to your site and remains your point of contact for technical support once the robot is in service.

Background

Unitree Robotics and the R1 family

Unitree Robotics built its reputation on legged machines, first quadrupeds and then a growing range of humanoid robots aimed at research, education and applied development. The R1 line is the company's compact humanoid family, and the sources name several versions within it: the R1-A5, the R1-A5-D, the R1-A5-D Smart A, Smart B and Smart C packages, the R1-A5-D Ultimate B, and the R1-A7 and R1-A7-D. For a buyer, the practical point is that each name describes a specific combination of platform and equipment, and figures belong to the version they describe. The Smart B is one package built on the R1-A5-D platform, and this page describes that package only.

Wheels, a lifting column and a camera in the hand

The R1-A5-D variant adds a wheeled chassis and a lifting column, taking it to 16 degrees of freedom. Those joints are distributed as 5 per arm across two arms, 1 in the waist, 2 in the head, 1 in the pillar and 2 in the base. The column lets the upper body change its working height, while the chassis moves the robot between work areas. On top of that platform, the Smart B package specifies two items: the Dex3-1 Hand (with RGB Camera) for dexterous handling, and a built-in Orin Nano 40 Tops compute module for running perception and control software on the robot itself. Together they turn a mobile dual-arm body into a self-contained manipulation station.

Technical Specifications

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

The manufacturer has not published the battery capacity, the IP rating, the maximum travel speed, the operating temperature, the payload of this exact configuration or the contents of the box; Robots Middle East confirms these at quotation.

What does the Smart B package add to the R1-A5-D?

The R1-A5-D defines the body: the wheeled chassis, the lifting column, the two arms with a forearm and upper arm length of 420 mm, and a head that turns through Y: ±115° and tilts through P: ±36°. The Smart B package defines what that body can do at its fingertips and how much reasoning it can carry on board.

The first addition is the Dex3-1 Hand (with RGB Camera). A dexterous hand allows grasps that a simple gripper cannot attempt, and the camera built into it gives software a close view of the object at the moment of contact. That complements the head-mounted MID360 LiDAR and stereo camera, which see the scene as a whole. In practice, a developer can let the head locate a target and the hand camera refine the final approach.

The second addition is the built-in Orin Nano 40 Tops module. It sits alongside the 8-core high-performance CPU + 10 TOPS computing power in the head and the 8-core high-performance CPU in the body, giving the Smart B dedicated capacity for vision and learning workloads without an external computer tethered to the robot. The Smart A and Smart C packages share the same platform name, and Robots Middle East sets the packages side by side for you when preparing a quotation, so that you choose on clear differences rather than assumptions.

Why choose a wheeled humanoid for manipulation work?

Walking is an impressive capability, but much laboratory and service work happens at benches, shelves and tables, where the robot needs to reach and handle rather than step. A wheeled base keeps the upper body steady while it works, and a lifting column changes the working height without asking the legs or the arms to compensate. For tasks centred on hands and eyes, that design spends the robot's mechanical budget where the task actually is.

The R1-A5-D also stays manageable in size and mass. With the column raised, it measures 1323 x 520 x 440 mm, and it weighs about 30 kg with its battery. The battery is removable and housed in the chassis, which suits laboratories planning several sessions in a day; the battery life is approximately 1.5 hours per battery. Wi-Fi 6 and Bluetooth 5.2 handle connectivity, and OTA updates are supported, so the software can be kept current without returning the robot.

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

The clearest fit is the manipulation research group. Laboratories working on grasping, tactile and visual servoing or embodied AI gain a hand with its own camera, a head with LiDAR and stereo vision, and on-board compute, all on one mobile platform that can be moved between test areas.

Universities and technical colleges form a second segment. A wheeled humanoid of this size can be shared between student teams, and it covers perception, motion planning, manipulation and navigation in a single teaching programme.

System integrators and corporate innovation teams are a third. Those evaluating service, retail or light logistics tasks can use the lifting column and dual arms to prototype picking and placing at different heights before committing to a larger deployment.

Buyers who mainly need the mobile dual-arm body, and intend to fit their own hands or computers, may wish to compare the Unitree R1-A5-D Mobile Base Dual-Arm Humanoid Robot. Those weighing alternative packages can review the Unitree R1-A5-D Smart A Humanoid Robot and the Unitree R1-A5-D Smart C Humanoid Robot, or browse the full Unitree R1-A5-D range and the wider Unitree R1 family. Robots Middle East will set out the differences between these packages in writing.

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

1. Dexterous grasping research — studying how a multi-fingered hand closes on objects of different shapes and textures.
2. Vision-guided manipulation — combining the head sensors with the hand camera to plan and correct each approach.
3. Embodied AI experiments — running perception and policy models directly on the built-in Orin Nano module.
4. Robotics teaching — giving students one platform for perception, navigation, manipulation and system integration.
5. Indoor mapping and navigation — using the MID360 LiDAR and stereo camera to build maps and move between workstations.
6. Service task prototyping — trialling shelf picking and table handling at varying heights with the lifting column.

The head carries a MID360 LiDAR and a stereo camera. The Smart B package adds the RGB camera built into the Dex3-1 hand.

What computing power is on board?

The Smart B package includes a built-in Orin Nano 40 Tops module. The head has an 8-core high-performance CPU + 10 TOPS computing power, and the body has an 8-core high-performance CPU.

Can the robot's software be updated?

Yes, OTA updates are supported. The robot connects over Wi-Fi 6 and Bluetooth 5.2.

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

Summary

The Unitree R1-A5-D Smart B Humanoid Robot answers a simple question: what if the robot could see the object from its hand as well as from its head? The R1-A5-D platform supplies the wheeled chassis, the lifting column and 16 degrees of freedom; the Smart B package supplies the Dex3-1 Hand (with RGB Camera) and a built-in Orin Nano module to make sense of what both viewpoints capture. For laboratories, universities and integrators who want looking, approaching and handling in one mobile body, supplied and supported by Robots Middle East, this page is the starting point.
