Invention: Rosie Copter

A home robotic drone that flies around the house doing your bidding.

Expert opinion from my friend leevonk:

problem is lift capacity. Need big/powerful rotors to pick up a beer. Not
sure on the array of bidding that it would be capable of helping with,
although as a telepresence thing for the office, it would much _much_
cooler than the existing ground based units! Imagine your face on a
smartphone screen being carried by a quadcopter through the office. You
could use it to take tours of factories/office buildings from a birds eye
views too
