Love being part of what’s coming next! 🚀

Biological intelligence to bootstrap robotic intelligence?

If robotics is about to enter its golden age, @MeckaAI is one of the companies feeding it, by sensorizing humans to train robots.

The biggest challenge robotics faces is the data flywheel cold start problem. LLMs got a free cold start from the internet: trillions of tokens, already written. Robotics gets nothing. Someone has to go create the training data to jumpstart the system.

@joshavata is the co-founder and CEO of Mecka, the data and deployment company for physical AI. Josh read every robotics paper he could find in late 2024, visited the labs, and made a bet: humans and humanoids look the same, so humans could act as the training fleet. Egocentric data, first-person video of people doing real work, could become vital fuel.

Two years ago, the biggest egocentric dataset was Ego4D at 4,000 hours. The field is now in the millions of hours, thanks in part to Mecka. We’re probably still orders of magnitude of training data away from robotics nirvana. But every rung on the physical intelligence ladder unlocks real commercial tasks. And eventually, Josh imagines a world with an order of magnitude more robots than people, of a plurality of shapes and sizes and use cases, as the Hitchhiker’s Guide to the Galaxy foretold :)

A few things we cover in this conversation.

- Why robotics has no cold start: pixels, actions and logic, and why pre-training data is a real market in robotics in a way it never was for LLMs

- What “teaching robots about carbon life” means: in sci-fi the final frontier is organic. The human brain runs on 20 watts and self-heals

- The egocentric bet: teleop couldn’t scale, humans and humanoids share a form, so Waymo-fy the humans. The first pilot was aunties and uncles recording themselves cooking on a mobile app

- Force data: video can’t tell a robot how hard to squeeze an egg. Wrist cameras are a hack. Mecka built the gloves instead

- Inside the data factory: a consumer app that streams your tasks, a B2B engine recruiting across “the taxonomy of all physical human work,” 100-gigabit upload lines, hundreds of petabytes

- Millions of hours vs. Tesla’s decade on two degrees of freedom, and why it’s a slow creep up, not a GPT-3 moment

- The home has the most data and is the hardest place to deploy. Laundry folding and assembly-line pick-and-place get solved in the next year or two

- Useful robots already exist: hotel delivery and cleaning bots in China and Southeast Asia, industrial cleaning in the US. Humanoids are the terminal state, not the first step

- Deployment diffusion: a modern systems integrator whose installed robot does something next week it couldn’t do last week. If Mecka ever helps deploy a robot that mines an asteroid, they’ve done their job

- The data pot of soup: a million hours of human data, tens of thousands of UMI, a few hours of in-domain teleop. Tactile and simulation haven’t entered the mix yet

- Move 37 for robotics: AlphaGo went behavior cloning, then self-play, then magic. The catch is the rules of the game are the entire physical world, and we don’t have the simulator yet

- Will the AGI labs steamroll robotics? “It takes a lot of courage to scale up data with imperfect information.”

- The Kawasaki Corleo, the robot panther-dog-horse on Mecka’s conference room wall, and why the future of robotics looks like Hitchhiker’s Guide to the Galaxy

Onwards and upwards! 🚀

[Josh @joshavata]

Today @MeckaAI is announcing a $60M Series B from @sequoia to accelerate the advent of general purpose robotics

This brings our total funding to over $120M to become the data and deployment layer for physical AI

Read more below 🧵

[Harshavardhan Reddy @itsghvr]

LLMs got better because we had good evals. Physical AI doesn't have those yet.
This is our team's first step towards having multi-industry evals!

Lots learned, and more benchmarks coming soon!

[Josh @joshavata]

Are robots ready to accelerate science labs?

We created the WetLabs Benchmark to test 9 critical tasks, from easy to hard, and let 3 leading models take 20 attempts per task

Astra leads but it comes close...

[Harshavardhan Reddy @itsghvr]

@manoela_schmitz @joshavata Stirring and taking a tube out, flipping it, and putting it back was the hardest. None of the models managed either. Even just picking up and placing lab equipment was pretty hit or miss.
