I really wish you could build a robot that could "bring out the trash" with just $1 MM, but robotics is not so forgiving. Anki, which raised around $200 MM, started with advanced toy robots and were shifting towards a home chore robot and ran out of money before they had a prototype. The only company I know with a viable solution in this space, and honestly I am stretching 'viable' in terms of what it can do for what it costs, is Boston Dynamics. It'll be interesting when someone finally leaks a price for SpotMini - I'd guess something like $60k.
