Tatbot draws its friends. Fifth portrait: Bot Ross, the painter bot by @cdngdev, a small 3D-printed arm that learned to paint the Golden Gate Bridge.

i gave astra a robot, a paint brush, and a camera then asked it to paint the golden gate bridge in real life!
it figured out how to control the robot, and progressively got better throughout its attempts. the timelapse is sick

Everyone's been showing Fable and GPT-6 Astra driving robot arms.
We trained an open 27B Qwen model to do it, purely from its own attempts in simulation, with zero demonstrations.
And it can run locally at 220+ tok/s on an RTX 5090.
On a real robot it had never touched, it now succeeds in 18 of 30 tests, up from 0 before training. It also copies a painting and designs its own chemistry experiment.
It generalizes and follows instructions better than π0.5, and on LIBERO it comes close to Astra max.
All without losing its general capabilities, like math and coding.
Built on Qwen3.8-27B. We've open-sourced the model weights, code, and full training infra! Check out our blog at mit-han-lab.github.io/pear-b….

Tatbot draws its friends. Second portrait: the watercolor painter bot by @dhvanil, which painted an autumn tree overnight.
The painting that inspired it: teapaw.org/dhvanil/status/2118756…
i went to bed and asked claude to paint an autumn tree overnight.
at around 4am, it realised that it didn't have some shades -- so it stopped and titrated its own paint: diluting red, sienna and madder step by step on a second palette, then measuring each pocket from a photo.
woke up to this beautiful watercolor painting. 303 brush marks, took about 4.5 hours 🍂 (still working on the speed)

Drawings so good we ran it back again
@newtheoryai @MissionRobotBay
Thanks for all the wonderful talks and wonderful pictures!

Tatbot's simulator now breathes. In MuJoCo 4, the tattoo stencil warps with moving skin while our real detector tracks every tile.

Would you let a robot give you a tattoo?
He did.
@stash_pomichter had an awesome San Francisco robot party to celebrate new office with a ton of robots.
Tatbot's new rig: a UFACTORY xArm 7 running DimOS, tattooing the Dimensional logo on silicone skin. See it live tonight at the Dimensional Office Warming in San Francisco.
