bartman.. not too sure if you still read this thread but just to update you.. the book that i lent to a friend of a friend... guess what that dude is not even in the country anymore and he took my book with him. but in the book that you bought there is a Hexapod Walker (Chapter 10) but its a basic one that you find on a lot of personal hobbist *there should be a spell check on the forum * websites. I suppose the reason its in the book is because it was easy to build for beginners. I just bought the AMPHIBIONICS the other day. next project at hand is building the robot snake.
