humanoids are research into locomotion, copying anatomy with steel. articulation of 1 or more joints. balance. Most of the work is being done in software, how to control 2 legs, balance, move forward, turn, etc.
autonomous robots are research into navigation, sensors, data fusion, how to represent problem in software?
Industrial robots are working examples of the above two areas. They copy anatomy (robot arms), and figured out how to sense, represent the problem in software, and how to articulate the limbs. This is the only area where commercial units are in place and have been for 20 + years.
home appliance robots are appliances mounted on robot bases. The only ones I've seen have preprogrammed (by user) path to follow.
autonomous vehicular robots are motor vehicles with on board computers. they can navigate the vehicle over rough terrain.
