Figure 03, our 3rd generation humanoid robot

Then the robot would just go to its station and swap its own batteries. Why even have wireless charging at all? Or even a cable? Or even have it "charge"? Battery swapping seems to make way more sense here. Am I missing something?

Bonus points if the robot has data on the degradation and can order its own replacement batteries, take them out of the box, and ship the old ones to a recycling facility...

More bonus points if the charging station is actually outside under a 1KW solar array pergola thing, that way you don't even have to pay for the electricity either. Don't worry, the robot will lock the door when it goes out to grab its batteries. It'll also bring in the whole setup if the weather isn't great.

But a cable is a fair question.. you'd think it could plug itself in...

Maybe that's a hint at the robots actual capabilities at this point... or, they didn't want to bet on the unpredictability of environments: what if there's something in the way of the cable, though something could also be in the way of the inductive charger

There are practical advantages to being able to charge wirelessly, sure. But if they're doing that because of AI limitations? Bad sign.
