I have only recently entered the world of robotics and was looking for a decent entry level book. I found 2. "JunkBots, Bugbots, and Bots on Wheels: Building Simple Robots With BEAM Technology", which I have already reviewed and this one. As with my other purchase, this book is an absolute must for those, like me, who are entering the magical world of robotics. Each step is clearly explained in "idiot's terms" with much humour to lighten this daunting subject. I cannot recommend this book highly enough and for the price, well what are you waiting for? Buy It! You'll be so glad you did.
