Unitree R1 vs G1: what the extra $8,600 buys
The cheap one is real: the $5,900 Unitree R1 carries 26 joints to the $13,500 G1's 23, and both lift about 2 kg per arm. The extra money buys sensing, runtime and headroom (3D LiDAR plus a depth camera, about 2 hours per charge instead of about 1, an EDU path to 43 joints), and neither base model lets you write code for it.
Both robots are real, both ship from the same store, and the cheap one is not a stripped toy version of the expensive one. As of 2026-08-07, Unitree lists the R1 from $4,900 and the G1 at $13,500, tax and shipping excluded on both. That is an $8,600 gap at the R1's floor, and the first surprise is that the money does not buy joints: Unitree's own spec table gives the $5,900 R1 26 degrees of freedom against the G1's 23.
So the real Unitree R1 vs G1 decision is which set of compromises suits the work you have in mind.
The prices, as the maker lists them
Unitree quotes two different things in two places, which is where most of the confusion in this comparison comes from. The store shows one headline price for the R1 listing. The product page breaks the family out by trim.
| Model | Price (2026-08-07) | How you buy it |
|---|---|---|
| R1 AIR | $4,900 | Cart, maker-direct |
| R1 | $5,900 | Cart, maker-direct |
| R1 EDU | Contact Sales | Email sales_global@unitree.cc |
| R1-D | from $4,290 | No cart on the page, contact sales only |
| G1 | $13,500 | Cart, maker-direct, currently backordered |
| G1 EDU | Contact sales | Email sales_global@unitree.cc |
The store's "from $4,900" is the AIR trim. Buy the R1 people mean when they say R1, the one with a waist and a head that turns, and you are at $5,900 against the G1's $13,500. Call the real gap $7,600 to $8,600 depending on which R1 you pick. For the full R1 stock picture, including which colorway is backordered this week, I keep the R1 tracker page current.
The cheapest number in that table, the one with no cart behind it, is not a leak or a reseller quote. Unitree put it out itself.

Where the money actually goes
Three rows carry almost the whole $8,600.
Sensing. The R1 sees with one camera on the AIR trim and two on the R1. The G1 carries a depth camera and a 3D LiDAR. If your project involves mapping a space, avoiding things it was not told about, or grasping something whose position it has to work out rather than be handed, that difference is the purchase. It is the single largest capability line between the two.
Runtime. About 2 hours on the G1's 9,000 mAh pack against about 1 hour on the R1. Both are quick-release smart batteries, so both can be leapfrogged with spares, but a lab running back-to-back trials feels the halving.
Headroom. The G1 EDU scales to 43 joints, adds waist and wrist axes, takes the seven-DOF Dex3-1 three-fingered hand, and lifts its knee torque from 90 Nm to 120 Nm. The R1 EDU scales to 40 joints and takes an Orin compute module (Unitree quotes 40 to 100 TOPS). Both upgrade paths are quote-only, so neither has a published price, which matters more than the base sticker if you are buying a platform to grow into.
What the money does not buy is lift. Both base machines list an arm figure of about 2 kg, and only the G1 EDU moves it to about 3 kg. Anyone imagining the expensive one carries groceries and the cheap one does not should look at that row twice. Neither carries groceries.
The line both robots share
One row decides more purchases than the price does, and it reads identically on both store pages: "This product does not support secondary development. For customization needs, please select the EDU edition."
That is on the R1 listing and the G1 listing, and the parameter tables agree: secondary development is a "yes" only in the EDU column. So if the plan is to write code and run it on the robot, every trim with a cart on it is the wrong purchase, and the right one carries no published price at all.
The same R1 page also advertises "Fully open joint & sensor interfaces, plus native simulation platform support." Both sentences live on the same page. Read them together as: open interfaces, restricted trim. Before you spend, email sales and get the EDU quote in writing. That figure is the real developer price.
Unitree does not hide the framing either. Its G1 page states that "the global humanoid robot industry is in the early stages of exploration" and that "individual users are strongly advised to thoroughly understand the limitations of humanoid robots before making a purchase." A maker writing that on its own product page has earned some credit.
The costs after the sticker
Identical on both listings, and identical to the rest of the China-direct tier described in the cheapest humanoids you can order:
- Shipping between $300 and $1,200, quoted on the product page.
- Buyer pays all customs duties, taxes and import clearance, and must supply a phone number and email for clearance.
- Short warranty. Six months on the R1 AIR, eight on the R1 and the G1, per Unitree's spec tables. The store checkout pages state no warranty at all, so the tables are the only figures on the record.
- No described US service network. A fault on a 35 kg G1 means self-repair or an international shipment.
Stock: the G1 listing reads backordered, the R1 listing reads In Stock, with the R1 Air (White) backordered until it returns.
Which one to buy
Buy the R1 at $4,900 or $5,900 if you want a walking biped in the room for the least money, if your work is locomotion, teleoperation, or plain demonstration, and if one camera or two is enough eyes for it. It is the cheapest real humanoid with a working checkout, and at 26 joints on the $5,900 trim it is not the lesser machine on paper.
Buy the G1 at $13,500 if the robot has to perceive space rather than just move through it, if an hour of battery is a scheduling problem, or if you expect to grow into the EDU tier, where the ceiling is meaningfully higher: 43 joints, a force-controlled three-fingered hand, an 18-month warranty.
Buy neither if you want a robot that does something in your house. Both are platforms sold to people who write code, and the tier above them keeps that same label: the H2 is $29,900 and the H1 is $90,000, and they are no more domesticated than these two.
A last piece of arithmetic. The G1 has come down in price, from $16,000 at launch to $13,500, which I chart with the archived store captures in the G1 price history. The R1 undercuts it by more than half. Two years ago neither number existed. For where both land against everything else with a checkout, see the full humanoid price ladder, and if you meet either robot at a marked-up reseller price, the direct listings above are the ones to beat.
