This is a 3-D printed Arduino programmed 14 servo/DOF animatronic octopus hat. It has a gyroscope built in to sense a change in direction so the two side tentacles respond to yaw rotation, and the two top tentacles respond to pitch up/down rotation. It is mounted on a wooden bust of my head as a holder. It is running off an Arduino Mega with DFRobot IO shield. I upgraded the software in this version, not perfect but decent enough for a video. It is all made from PLA, designed on Sketchup. The code is my own.
