I notice that the reviews for this book tend to be 5 star or 1 star. I can understand both stances.
I think that the concept of packaging the actual robot parts with the book is really nice. The little Stiquito is sort of nifty, but not something you'll be likely to impress your friends with, unless they are the very nerdy type. Actually, even if they are the really nerdy type, they might not be impressed. It is nevertheless the six legged walker with a tripod gait. Nifty.
Building the Stiquito is sort of delicate. Good thing the instructions are good. You learn to appreciate the details of constructing something so simple. You learn simple things like securing the end of a piece of wire are not always so simple. Those with limited patience and limed manual dexterity may want to avoid this book.
I should be mentioned that the Stiquito is just a 'platform'...it walks if you control switches in the right way to make it walk. It is not in ANY way antonomous.
The informations about how to go beyond the simple little robot which doesn't even have a brain is not very in-depth, but good enough to get you moving on. Actually, if you are really interested in nitinol wires, this book does a pretty good job going through the various other nitinol based robots.
Personally, I think a kit that costs maybe three or four times as much, but has more parts to play with might be better, but then again I love robots and I'm not afraid to pay for robot stuff. For those testing the waters of a new hobby, and are good at delicate handiwork, this might be a good purchase.
