This book was complete trash. First off battle bots are the easiest type of robots to build. The programming is so simple that even a child could do it. This isn't some amazing book. People tell me, "well they had to use trash for their bot." That would be impressive if every other underfunded school didn't do the same thing the chassis of my bottom that I had to build was from a scrap yard. This is nothing new to the world of robotics and to go as far as making a book that makes this look like something that never happens is a joke.
