Halloween presents a great time to build and exhibit some scary animatronic creatures. In fact, some of the robotics kit that is now taken for granted was developed for movies using animatronic techniques.
Those techniques have been used to great affect in films and now this is quite accessible to robot builders. Looking around on instructables, just before halloween has revealed a few cool but creepy instructions on building your own animatronic horrors.
First up - the Animatronic Rat. On instructables.com, some chap has created a rat which uses servos to move, has creepy LED eyes, and can squirt victims with water from a jet in its mouth.
The Simple Reaper
This animatronic reaper is simply an oscillating fan, with a mask, sickle and cape. It is still pretty creepy and cool though.
A bunch of potential jaw dropping animatronics
Finally, another builder submitted how to do a skull with moving eyes and mouth, and a talking pumpkin using servos, and a controller. This includes some really fiddly connections, but they are shown up close and in enough detail to have a go. It also shows the software and techniques used to bring the gear to life.
Have a good look around Instructables - there is plenty there to build. Enough to keep anyone occupied. I would also encourage my readers to submit their own cool builds and howtos there too!
