I bought Junkbots, Bugbots & Bots on Wheels yesterday after going through the archived articles on this site and reading the review. It's a little basic but as someone who has really only worked with an FPGA robot and microcontrollers, it's nice to now have a nice, gentle intro to some simpler designs.

Unfortunately, it's exam time and I'm already regretting the little time that I have spent reading the first few chapters (instead of studying).
