COMPAREE VERDICT

ALOHA is the project behind that viral clip of a robot cooking and cleaning — and the real thing is a bimanual teleoperation rig from Stanford that learns tasks from human demonstrations. You puppeteer two arms to show it a job, and after roughly fifty demos it performs the task autonomously with surprisingly high success. Set expectations correctly: the main repo is mostly software (ROS teleop and data collection), the physical build rides on commercial Interbotix arms, and the BOM is a Google Doc rather than a full CAD pack. So this is less 'print a robot' and more 'assemble a serious learning platform.' If modern robot learning is what excites you, few projects get you closer, hands-on.

NOT IN THE REPO

  • The main repo is mostly SOFTWARE (ROS teleop + data collection)
  • Some STL/CAD is in the aloha2/ folder (mounts, gripper parts, assembly PDF) but it's not a full CAD pack
  • It's built on commercial Interbotix ViperX/WidowX arms — the BOM lives in a Google Doc
  • Training (ACT) is a separate repo

Can I build this?

Printcamera/gripper mounts from the aloha2/ folder (partial CAD)
Buycommercial Interbotix ViperX/WidowX arms, multiple USB3 cameras, a workstation
Toolsassembly + a solid Linux/ROS setup
SkillsROS, Python, robot learning; comfortable with a research stack
Timea serious multi-week project
Costband $$$ — the commercial arms dominate; current prices: creator's BOM doc
Safetythe arms have no brakes — they drop when torque is off; support them during setup

Build at your own risk. Projects involve tools, electronics and sometimes mains voltage — follow the creator’s safety notes.

  1. 1.Read the project page (the original ALOHA)
  2. 2.Watch the demo (why it went viral)
  3. 3.Read the paper (ALOHA + ACT)
  4. 4.Get the hardware assembly doc (the Google Doc BOM/assembly)
  5. 5.Train with ACT (separate training repo)

KNOWN ISSUES

  • The main repo is mostly software — the physical build rides on commercial Interbotix arms, and the BOM is a Google Doc
  • The arms have no brakes: they drop when torque is removed — support them during setup
  • You need several USB3 cameras; cheap hubs add latency that hurts data collection
  • It's ROS1 (noetic) — plan your environment accordingly

Is this the Google DeepMind ALOHA 2?

No — this is the original Stanford ALOHA (and Mobile ALOHA). DeepMind's ALOHA 2 is a separate, later effort.

How little data does it need?

Roughly fifty demonstrations (about ten minutes of teleoperation) can reach high success on a task — that data efficiency is the headline.

Do I need to print the whole robot?

No — it's built on commercial Interbotix arms. You add mounts, cameras and the software; some parts are in the aloha2/ folder.

What does it cost?

Band $$$ — the commercial arms are the big cost. The BOM doc has current figures.

FROM THE COMPAREE TEAM

ALOHA reaches high task success from roughly fifty human demos — about ten minutes of teleoperation. Is imitation learning at that scale ready for your kitchen, or still a lab trick?

CompareeTEAM1mo ago

A detail we didn't expect: the Interbotix arms have no brakes, so the moment torque is cut they just drop — the docs tell you to physically support them during setup. We also noticed the whole physical BOM lives in a Google Doc rather than the repo, which is mostly ROS teleop software. Anyone running this on ROS1 noetic in 2026, or have you ported it?

Tony Zhao, Zipeng Fu, Chelsea Finn (Stanford)

A Stanford team open-sourced a low-cost bimanual teleoperation system and the ACT learning method, showing robots can learn real tasks from a handful of human demos.
