Motion control proof of concept. The cams push on the levers, which pull on strings that point in different directions. By controlling up to three strings for any point, the dragon can be made to go through an arbitrarily complicated motion.

Kinetic Sculpture Project: Dragon
Over the next semester, I will be attempting to design and build a kinetic sculpture consisting of a simple dragon puppet animated by a system that will use a hand crank to turn a cam shaft, push a series of levers, pull on strings attached to key points on the dragon’s wings, body and head and, hopefully, program a fluid and convincing motion cycle without using any electronic components whatsoever. This is a rehashing of a similar project I attempted four years ago, but with a much more complicated motion control system, much lighter dragon and much larger scale; while the previous version was made of metal, featured a dragon with a wingspan of 18 inches and operated by wooden gears, this version will be made almost entirely from wood, operate a dragon more than six feet in wingspan and use the far more flexible cam-based system outlined above instead of using gears. This project is being made possible by a grant from the Brown Design Workshop, a student-run maker space affiliated with the Brown University School of Engineering.
