>>11002841Yeah, energy density is pretty shitty all across the board for a form factor that small. The only thing left to us is device efficiency and design efficiency. Just having some wheels that can lock solid to act like feet or unlock and roll (either powered or unpowered) to save energy could be a game changer. I mean something like this, but also including the ability to use the wheels as though they were skates, powered wheels, and/or feet and in any combination of that would lower power needs drastically in many situations.
