         | 
         | 1. Force. Walking, running, fighting, doing backflips, etc. all
         | allow for large amounts of force, without a lot of _dynamic_
         | precision required. Many common tasks require precise and

         | 
         | 2. Environment interaction. Most reliable humanoid robots do
         | minimal environment interaction beyond self-balancing. They
         | walk/run/jump in environments that are largely open, with

         | solid/open space. E.g. I'd want to see a robot that can walk
         | through a forest: jumping/stepping over thin branches that are
         | hard to see, ducking under fallen logs, pushing though bendy
         | branches without breaking them, avoiding ground that is muddy,
         | and seeing through the current obstacle to determine if the
         | obstacle beyond is traversable.
         | 
         | Just to reiterate, I don't see fast progress being made on
         | doing these tasks _reliably_. It 's easy to show 1/N success
         | rate, and much much harder to show ~N/N success rate on these
