Animatronics is tricky. It requires mechanical engineering in addition to the software and electrical engineering of most of our projects. Normally when I talk with cosplayers just getting started with electronics, I point them toward a light or sound project, to limit the number of variables.
This project reduces animatronics to its simplest case. Mechanical tails are complex stuff, often involving armatures for bones and cable mechanisms to simulate muscles and tendons. Rather that fighting against gravity, we’ll instead make it our ally. Thinking of the tail as a pendulum, a single small servo and a little math is all it takes.
Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Since then Adafruit has grown to over 25 employees in the heart of NYC. We've expanded our offerings to include tools, equipment and electronics that Limor personally selects, tests and approves before going in to the Adafruit store. We pride ourselves on having great prices, the best customer service, technical support and fast shipping. We hope we can assist you on your journey of learning - At Adafruit we celebrate engineering happiness!
