Grumpy: robot with some personality
This is my power functions robot named Grumpy.
Like other robots he has some basic functions like:
-lower and raise his arms
-open and close his claw to pick things up
But that wasen't enough for me. I wanted him to have some personality. To do that I added some head movements. He can shake his head left/right and move his neck back- and forward. While driving he always looks in the direction he's going. He can also move his eyebrows up and down.
For all these functions only four motors where needed!
I hope you like it.
