Incredibly simple method to induce novel task solving during inference time: warm start denoising with human priors!.
Presenting DemoDiffusion: An extremely simple approach enabling a pre-trained 'generalist' diffusion policy to follow a human-demonstration for a novel task during inference. One-shot human imitation *without* requiring any paired human-robot data or online RL 🙂. 1/n

As someone who has often just done this based intuition, this would be super useful in general ngl. Would love to see a slightly more formal treatment.
I wish there was a good venue to write/present about RL “tricks”. how PD gains affect action scale, how to tune reward functions, actor STD, etc. there’s good intuition for all of it, grounded both in learning theory and robot dynamics, but I don’t often see good explanations.

Hopefully one day we will have FSD deliver Optimus to customer doorsteps too :P. Or a legion in a Tesla Semi, that would be cool.
The first fully autonomous delivery of a Tesla Model Y from factory to a customer home across town, including highways, was just completed a day ahead of schedule!!. Congratulations to the @Tesla_AI teams, both software & AI chip design!.

Incredibly excited to share that Neural MP got accepted to IROS as an Oral presentation!! Huge congrats to the whole team (@Jiahui_Yang6709, @mendonca_rl , youssef khaky, @rsalakhu, @pathak2206), but especially @Jiahui_Yang6709 for making this happen after I graduated! This now.

Massive congrats to our neighbors in the office (aka the autopilot team) for making this happen! As an avid FSD user I'm especially excited, this is just getting us one step closer to the future where we don't have to pay attention to the road at all and just let the car drive!.
BREAKING: First ever Tesla Model Y robotaxi with no-one in the drivers seat spotted testing on public roads in Austin, Texas!. Tesla's new "Robotaxi" wordmark/logo is on the side of the vehicle.

Really cool work from @g_k_swamy and co! Sample efficiency gains by leveraging search in world models is a cool way to enable test time reasoning for robotics!.
Say ahoy to 𝚂𝙰𝙸𝙻𝙾𝚁⛵: a new paradigm of *learning to search* from demonstrations, enabling test-time reasoning about how to recover from mistakes w/o any additional human feedback! 𝚂𝙰𝙸𝙻𝙾𝚁 ⛵ out-performs Diffusion Policies trained via behavioral cloning on 5-10x data!

I’ve only been at Tesla for a few months, but I’ve never been more impressed with a leader. Not only are you incredibly knowledgeable about pretty much every technical part of Optimus - from hardware mechanical and electrical to even AI, (that’s honestly kinda insane if you think.
Over the past 9+ years, I’ve had the immense privilege to work with some of the most brilliant minds in AI & engineering. I’ve built friendships that will last a lifetime. This week, I’ve had to make the most difficult decision of my life and will be moving out of my position.

Yeah this was the challenge I was trying to address during a large portion of my PhD as well. I had a similar intuition/finding that horizon is the problem - with a different set of solutions. What worked well in the end: Locally robust pre-trained skills + motion planning + VLM.
The fact that current RL methods struggle at long-horizon tasks is something that I think most people understand intuitively; this is a really cool paper and bit of analysis explaining what's going on, and how to work around it. This remains to me an important issue that needs.

Great work by @ZhaoMandi and an excellent paper title 😛. Looking forward to a real robot follow up sometime soon I hope.

This is why we do what we do :).
"Robotics is going to be the biggest industry in the history of the planet. There's going to be. hundreds of billions of robots of all shapes & sizes running around doing all kinds of things". Don't take my word for it - hear it straight from @pmarca

Yeah its the grit + not really being afraid of hard problems anymore.
the most satisfying takeaway from a phd is that you can solve problems far beyond your capabilities if you're willing to throw yourself at them again and again, over a long period, while staying open to new ideas. it's not really about being smart. just curious & persistent.
