URI Learning athletic humanoid tennis skills from imperfect human motion data

Impressive! Looks like a nice alternative or evolutionary step for a
ball machine.

Very impressive. But it doesnât 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 âsolvedâ if you can estimate state well enough.

We know. Just appreciate it for what it is. Which isâ¦awesome.

Why can some Temu humanoid robot do this sort of impressive,
coordinated, high-speed thing, but Tesla Optimus completely sucks at
everything unless theyâre moving at 0.02m/s (and even then theyâre
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.

Relax, it is one demo. It probably can't handle the millions of edge
cases that exist in real life.

Iâd be OK (and from a product perspective think it would be a
win) if Optimus just mastered one high-value skill like clothes
folding. Yet, here we are.

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?

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

Maybe for novelty, but the rich usually just pay humans to act like
robots.

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

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