Yeah. Good idea! only thats what I've been doing ever since I started
building underwater robots. :-) The only problem is when you want to change
or repare something you have to perform surgery on your robot leaving a big
scar down the robot. Anyhoo, I have found the best way is to first build a
"Play-Doh" mould and make the outside layers first sandwiching the
electronics and mechanics inbetween that way you can get a nice evenly
shaped robot.
