Just make sure you don't confuse these piles of airplane servos with robots like Sony, Asimo, and Hubo.
These hitec robots simply play out servo positions over time.
However, the Asimo and Hubo robots both have fully autonomous functions. (example, serve drinks, recognize people, give directions) Sony, Asimo, and Hubo all have active balance control as well. The only thing keeping the Hitec robot on its feet is its center of gravity.
Just wanted to make sure you give Sony, Asimo, and Hubo the credit they deserve.
