Update 11/18/2016: Instructions for building this model are now available here.
Last fall, while looking for new projects to work on, I was inspired to build a kinetic sculpture of a horse. After many prototypes, several months of procrastination and what seems like hours of watching horse videos, it is finally finished.
It proved to be quite a challenge to reproduce the fluid motion of a galloping horse. I designed the system for the legs early on, but I really wanted to capture some of the other subtle movements involved as well. Like the slight rocking of the body, the forward thrust of the head and a little flick of the tail. All of that motion is driven through a single axle in the base, which can be cranked by hand or via a motor.
It is fairly mesmerizing to watch and as an added bonus even sounds a little like a galloping horse.
