The building instructions for these robots, representing five endangered animals---a sloth, gorilla, Komodo dragon, Polar Bear, and frog (a representative of thousands of endangered frogs)---are user-friendly, four-color, and thoroughly tested. Educational activities in math, literacy and critical thinking are included. All robots are built using the most common parts in the LEGO MINDSTORMS Education NXT Set (#9797) and the NXT Education Resource Set (#9648), and are easily modified for use with the NXT 1.0 or NXT 2.0 kits.
