Nick and Tesla's Robot Army Rampage: A Mystery with Hoverbots, Bristle Bots, and Other Robots You Can Build Yourself - Steve Hockensmith, Bob Pflugfelder

The build your own robot instructions look like a lot of fun but, for me, they are more intimidating. I think most parents/teachers and children could do them but they're more then I feel able to attempt on my own. They do provide the proper item numbers for the tiny motors (very smart) and most of the elements would be easy to find.

 

The story is also a lot of fun and I can't wait to see who the guilty party is!
