Always important to remember that a lot of these robots are "faking" the humanlike motions -- its a property of how they're trained not an inherent property of the hardware. They're actually capable of way weirder stuff and way faster motions.

Predicting how the environment changes over time is a key task in robotics, enabling all kinds of downstream tasks. Trace Anything is a very interesting look at how you can train models which predict the trajectory each point will take in the future -- you can use this for robot manipulation, video prediction, and more.

Watching the agibot x2 at the hackathon yesterday. I think there are a few extra degrees of freedom over the unitree g1 and you can really see it in the motion

Some random thoughts reading through the new RobbyAnt VLA paper: - 20,000 hours of data across 9 robots!! - damn, Chinese companies are going to trivially outscale the American ones on real robot data - It's really cool they train on depth; it means they can handle transparent objects really well for example - You can never tell how good these models are without trying them, since everyone trains on different robots, but from the results they show it does seem to clean up - cross embodiment scaling laws are really cool - if you have lots of robots do you need human video??

"A miniature Wukong holding a stick in his hand sprints across a table surface for 3 seconds, then jumps into the air, and swings his right arm downward during landing. The camera begins with a close-up of his face, then steadily follows the character while gradually zooming out. When the monkey leaps into the air, at the highest point of the jump, the motion pauses for a few seconds. The camera circles around the character for 360 degrees, and slowly ascends, before the action resumes." From Genesis

Its funny how even with the wonderfully dynamic unitree g1, these actions are slow. Perception-> action and the embodiment gap are the big things slowing down robotics. This is the part of the video where they start manipulating stuff

One of my favorite works in the "robot learning from human videos" space that I have seen lately. This is because it offers a really coherent and unique way to represent robot skills without a lot of the downsides we see from estimation-based approaches.

Learning reliable manipulation skills for robots is probably the single most important thing for the field to accomplish. Generalist models are usually not reliable enough to achieve the ~100% reliability we really want. But Wenli Xiao has a recipe for achieving this, and for using the data to improve the base model too. Learn more here in the RoboPapers podcast with Michael Cho - Rbt/Acc ->
