To my knowledge robots are named after a Czech word for forced labour. Therefore my definition would be "A machine which carry out work autonomous." (very much like peteroakes definition). Workshopshed: the word "autonomous" rules out your lawn mower 
Drones are unmaned air vehicles traditionally used as target for aiming exercises. They always are remote operated. Nowadays the carry sensors and weapons, too. Use was to my knowledge only military until recently. I personally would not call my qadrocpter a Drone, because of the military implication. A drone is a flying military ROV.
