It is interesting to watch. The movements of the robot are robot-like. I mean, wtf, there were no robot playing tennis before, but I have an idea how a robot playing tennis would be like, and this video confirms my expectations. Sharp, unsure movements, a lot of hesitation, ...

Movies pictured robots like this long before this become possible, but how did producers guessed it?

Or maybe movies rendered different kinds of robots, but this video bring into my memory only those, that look like this. A kind of confirmation bias?

Very impressive. But it doesn’t solve the whole problem yet.

The robot and ball pose is estimated by high speed mocap cameras, and is fed to the policy.

I imagine estimating that with onboard cameras - how humans do it - is much harder.

Almost all of closed loop robotics is a state estimation problem. Control is “solved” if you can estimate state well enough.

Nothing constructive to say, besides that the video really shows we're entering into a Sci-fi era.

Really impressive. In a few years there will be robotic AI instructors for the wealthy and their kids

Why can some Temu humanoid robot do this sort of impressive, coordinated, high-speed thing, but Tesla Optimus completely sucks at everything unless they’re moving at 0.02m/s (and even then they’re not great)? Like, train this thing on the latent space of folding my clothes out of the dryer and I will send you my money.

This just makes me want to play tennis right now. Such an addictive sports.
