This is my dog model.

Today we brainstormed and eventually created prototypes of our moving animal project. We initially designed a complicated dolphin involving gears, string and a large number of joints but soon realized that this idea would be not be practical and sought out a simpler design. My partner and I settled on building a moving tail controlled a circular joint and a rubber band, the gears from the previous version of our project were repurposed into the dolphins body.
