This is my power functions robot named Grumpy.
Like other robots he has some basic functions like:
-driving back-/forward
-turning
-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.

Wow! That is such a clean-looking, well-built robot! I'm amazed! The video is so well put together as well.

Now for my new 3-questions survey

1) What inspired you to build the robot?
2) How long did it take to make?
3) What are your future plans with the robot?
