Some days ago, I received a copy of Fay Rhodes' new book "Robots Alive! Endangered Species" and this weekend, I started to build some of the very nice animals included (of which already two movies have been posted here).
First one was the leaping NXT Frog:
Building time: 20 minutes
Programming time: 3 minutes
Once I've worked through the book (which I like very much already now), I will post a complete review here.
