Unitree R1-A5-D Smart Ultimate A Humanoid Robot

Picture a lab bench that rolls to the work, raises itself to the right height and then reaches out with articulated arms. That is the idea behind the Unitree R1-A5-D Smart Ultimate A Humanoid Robot: a humanoid upper body that gives up walking in exchange for a wheeled chassis and a lifting column.

This product is available through this page, by quotation.

Background

Unitree Robotics and the R1 lineage

Unitree Robotics is known for compact, actuator-driven robots that research groups and universities can afford to experiment with. The R1 family belongs to that tradition. Within it, the R1-A5 is the base humanoid, and the R1-A5-D is the variant that adds a wheeled chassis and a lifting column.

The naming matters when you compare listings. The sources describe six named versions: R1-A5, R1-A5-D, R1-A5-D Smart A, R1-A5-D Ultimate A, R1-A5-D Smart H and R1-A5-D Ultimate H. The letters after the model code separate packages built on the same mobile platform, so every figure on this page is tied to the version that carries it.

Positioning and key technology

The R1-A5-D has 16 degrees of freedom. They break down as 5 single arms × 2, plus 1 waist, 2 heads, 1 pillar and 2 bases. The pillar is the lifting column, and the bases belong to the wheeled chassis. Together they let the robot change its working height and position instead of balancing on two legs.

The joint motor is a low-inertia, high-speed, inner-rotor permanent magnet synchronous motor. This design favors response speed and heat dissipation, traits that suit a robot that spends its day making small, repeated movements at a workstation.

The named packages then differ in what they add. The Smart A package carries an Orin Nano with 40 Tops built in. The Ultimate A package carries an Orin NX with 100 Tops built in, together with the Dex1-1 V2 dexterous hand.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation. The manufacturer has not published the dimensions of the arms, the operating temperature, the IP rating, the charging time, the list of included accessories or the network ports; they are confirmed at quotation.

The elevated dimensions are measured as follows: 1323 mm is the distance from the top of the head to the bottom of the chassis wheels, 520 mm is the chassis width, and 440 mm is the chassis thickness.

What does the wheeled chassis and lifting column change?

A legged humanoid has to solve balance before it can do anything useful. A wheeled base removes that problem. The robot moves across a floor on its chassis, and the engineering effort goes to what the upper body does once it arrives.

The lifting column adds a second advantage. Work in a lab or a workshop is rarely at one height. A bench, a shelf and a cart each sit at a different level. With a pillar counted among its 16 degrees of freedom, the R1-A5-D can change its reach vertically as well as horizontally. The waist and the two head joints add the ability to turn and look toward the task.

If you want the platform without a named package, the Unitree R1-A5-D Mobile Base Dual-Arm Humanoid Robot is the base version on the same chassis. The packages differ in compute and hand equipment, and this page covers the one named Smart Ultimate A.

How do the Smart and Ultimate packages differ?

The fact sheet separates the packages by compute and by hand. The Smart A package lists an Orin Nano with 40 Tops. The Ultimate A package lists an Orin NX with 100 Tops and names the Dex1-1 V2 dexterous hand.

In practice, the larger compute figure matters for teams that want to run perception or learning workloads on the robot itself. The named hand matters for teams whose experiments depend on how the end effector grips. If your work is lighter, the Unitree R1-A5-D Smart A Humanoid Robot is the natural comparison.

Who is the Unitree R1-A5-D Smart Ultimate A for?

University and institute labs are the clearest fit. A mobile, height-adjustable humanoid upper body lets a group study manipulation, human-robot interaction and embodied learning without building a platform first.

Technical schools and training centers can use it to teach robotics with hardware that looks and moves like the systems students read about. Integrators and product teams can use it to prove out a handling or inspection concept before committing to a custom build. Companies that want to evaluate humanoid manipulation on a real site can do the same.

Buyers who need only the mobile base and arms, and who plan to add their own compute, should look first at the base version linked above. The wider product range is grouped under Unitree R1-A5-D, and the family as a whole under Unitree R1.

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

1. Manipulation research. Arms, waist and a lifting column give a platform for studying reaching and handling tasks.
2. Dexterous-hand experiments. The Ultimate A package names the Dex1-1 V2 hand, so grasping studies can be run with the equipment from the start.
3. Onboard AI development. The built-in Orin NX with 100 Tops is meant for running perception and control software on the robot.
4. Teaching and demonstration. A mobile humanoid upper body gives students hardware they can see, program and discuss.
5. Integration pilots. Teams can test how a humanoid fits an existing workstation, bench or service area before scaling up.
6. Operational evaluation. Organizations can assess what a wheeled humanoid can and cannot do on their own site.

Frequently Asked Questions

How many degrees of freedom does the R1-A5-D have?

The R1-A5-D has 16 degrees of freedom. They are 5 single arms × 2, 1 waist, 2 heads, 1 pillar and 2 bases.

How much does the robot weigh?

The R1-A5-D weighs about 30 kg with its battery.

What are its dimensions?

The elevated dimensions are 1323 x 520 x 440 mm. The 1323 mm runs from the top of the head to the bottom of the chassis wheels, the 520 mm is the chassis width and the 440 mm is the chassis thickness.

What compute does the Ultimate A package have?

The R1-A5-D Ultimate A lists an Orin NX with 100 Tops built in. The R1-A5-D Smart A lists an Orin Nano with 40 Tops.

Which hand does the Ultimate A package use?

The R1-A5-D Ultimate A names the Dex1-1 V2 dexterous hand.

What does the lifting column do?

The lifting column is the pillar counted among the 16 degrees of freedom. It lets the robot change its working height at a bench, shelf or cart.

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

You can request a quotation on this page. The cost depends on the package and the options you choose, so it is given in the quotation and not printed here.

Summary

The Unitree R1-A5-D Smart Ultimate A Humanoid Robot trades legs for wheels and a lifting column, so that the bench comes to the work and the work gets the engineering attention. It has 16 degrees of freedom, a low-inertia joint motor, and in the Ultimate A package an Orin NX with 100 Tops and the Dex1-1 V2 hand.
