Deployment is what matters. Deployment is not solved.

If you missed @chichengcc's guest lecture on "Robotics: Beyond Algorithms" from my @ETH robot learning course, check it out on YouTube! He shares insights that are rarely taught & hard to learn in academia. 📽️ YouTube: youtu.be/tvFvIEOBKfM 📚 Course: cvg.ethz.ch/lectures/Robot…

Our recent findings on World Action Models (WAMs): the core advantage of WAMs is not test-time “imagination” of futures, but the training-time supervision from future video prediction. We propose Fast-WAM, which makes inference simple, fast, and policy-centric.


Skill Capture Glove aligns the hands, but what about the rest of the body? Human collectors vary in height and arm length, and are also visually different. We developed Skill Transform, a method that converts glove data into equivalent robot data with a 90%+ success rate.

We're done demoing. Time to deploy. Robotics isn't just algorithms. It's perf traces, calibrations, vibe ingress ESD tests. It's about making the sensible decision and pragmatic tradeoffs, again and again and again. ...


We just raised $165M to end robotics demos and deploy the world's first autonomous home robots into households this year.

We raised $165M at a $1.15B valuation to stop doing demos. 2026 is about 1) deployment and 2) research. We will start shipping Memo with our new frontier models in a few months. Our series-B is led by Coatue, with Thomas Laffont joining the board. ->🧵

In my recent blog post, I argue that "vision" is only well-defined as part of perception-action loops, and that the conventional view of computer vision - mapping imagery to intermediate representations (3D, flow, segmentation...) is about to go away. vincentsitzmann.com/blog/bitter_le…

Default case right now is a software only singularity, we need to scale robots and automated labs dramatically in 28/29, or the physical world will fall far behind the digital one - and the US won’t be competitive unless we put in the investment now (fab, solar panel, actuator supply chains).


If you're tired of writing code that only lives on a screen, join us in building software that gives people their time back in the real world. Sunday is hiring Software Engineers of all levels to bring our home robot to life. Reach out or apply here: sunday.ai/careers
