This instructable will walk you through how to build a robotic plush lizard
This mechatronic animal, dubbed Leopold the 17th (he went through 17 iterations), was developed as the second project for the Spring 2012 Things That Think class at The University of Colorado at Boulder. Leopold, a plush lizard that tracks light sources, dances to the song "I'm so excited" by the Pointer Sisters when finding a sufficiently bright source.
To make Leopold (or a close relative) you will need:
2 yards of the top body fabric (we used a polar fleece)
3 yards of lining fabric
2 yards of bottom body fabric (this may be the same as the top fabric)
Small amounts of felt (white, black, red)
1" x 2" x 2.5' pine board
6 - 1/2 inch hinges
1/4 in. acrylic sheet
1/4 in. basswood
