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.

Berry pickup from Kyber Labs Robot hands that can pick up fragile objects quickly will be important to solving long-tail of robotics problems not currently automated

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??

ManiFeel is a benchmark for contact-rich manipulation tasks. Force- and tactile-based tasks with occlusions and partially-observable state are going to be crucial for true general purpose robotics. Website:

Wuji hands used by genesis to do a wire harnessing task. This kind of thing was completely out of sight of robotics until a couple years ago and is now possible with off the shelf hardware.

The best humanoid robotics in the world from 10 years ago at the Darpa grand challenge. Its amazing how fast this has changed; imagine what this will be like in 10 years

Cool look at a fleet of Apollo 2 robots doing a variety of pick and place tasks. Actually this whole video showed quite a wide range of uses for their robot.

The best way to get robust, high-quality robot performance is through reinforcement learning; but RL in either the real world or a traditional simulation has lots of limitations. Instead, Jiazhi Yang in RISE does RL in a compositional world model. Learn more ->

Gears are the "muscles" of robotics; but with so many AI/ML folks getting into robotics now, you may not know what people mean when they say cycloid/strain wave/planetary gear, and, more importantly why they matter What are the advantages and disadvantages? What actually ARE these things? I made this over the weekend to try to help provide an intuition: Probably has some mistakes as I am no mechanical engineer but I think it's useful

The kind of things you can do with compliant/force aware teleop i guess. Another cool video of a highly constrained pick.

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.

This clip from Figure shows what's so exciting about end to end applications. Handling a messy, unstructured feed of objects like this would be very difficult to scale with traditional methods
