Their thesis is that you cannot get the training data for a robot in the home from a lab or a simulation. You have to actually put a robot in real homes with all their messy details.
But, how to do that safely? First they build a robot with low gear ratios, low weight, pinch points covered. So, if it literally falls on you it’s low risk.
Then they have humans teleoperating it in first-person VR with 1:1 hand control.
The more times humans do any particular task through the robot, the more the robot learns to do that task in real world situations.
It’s the most thoughtful plan for robotics I’ve seen yet by far.
