Some time ago we’ve covered the first part of animatronics tutorial from pyroelectro, where PIC microcontroller was able to move eyebrows with help of two servo motors. They haven’t been sitting around, but pushed things forward. They added couple of eyes along with eyebrows. As you may know eyes heed to be able move up/down and left right. For this purpose there are two servos needed per eye. This makes total four micro servos for both. And of course additional two for eyebrows.

Obviously system gets more complex, but in other hand robotic face looks more natural. It can do much more facial expressions. It seems that Chris ain’t stopping and plans on adding more features to his creation. What’s next? Mouth…
