Is it a throughput constraint given too much data from the environment sensors?
Is it processing the data?
I'm curious about where the bottleneck is.
Let’s see how it changes once these pipelines follow the LLM recipes to use more than just human data…
Some combination of distillation, new architectures, faster compute, can eventually attack these problems. Historically as long as something in tech has been shown to be possible, speed has almost always been a non-issue in the years afterwards.
For now even getting a robot to understand what to do in the physical world is a major leap from before.
One way of doing that is to write code with no bugs or unpredictable behaviour, a nigh-impossible feat - especially once you've got ML models in the mix.
Another option is to put a guard cage around your robot so nobody can enter pan-throwing distance without deactivating the robot first. But obviously that's not practical in a home environment.
Another option is just to go slowly all the time. The pan won't fly very far if the robot only moves 6 inches per second.
I think the future is in "softer" type of robots that can sense whether their robot fingers are pushing a cabinet door (or if it's facing resistance) and adjust accordingly. A quick google search shows this example (animated render) which is closer to what I imagine the ultimate solution will be: https://compliance-robotics.com/compliance-industry/
Human flesh is way too squishy for us to allow hard tools to interface with it, unless the human is in control. The difference between a blunt weapon and the robot from TFA is that the latter is very slow and on wheels.
Doing your demo is significantly easier if you've already programmed/trained the robot to recognize the specific objects it has to interact with, even if those items are in different locations.

By the way, they’ve open-sourced their π0 model (code and model weights). More information can be found here: https://github.com/Physical-Intelligence/openpi
