I don't understand why people try to make robots look like people. It's not very logical. Humans have two arms and two legs, because most living things have evolved to have four limbs. But robots don't have to be limited to natural forms. Of course, if we assume that robots will be climbing trees in the future, two arms and two legs are justified. But there are goats in nature that are much better adapted to moving on difficult and almost steep surfaces than humans. I believe that for robots, mankind could use a more efficient form that has been known for more than 2000 years - centaurs.
