First ideas and scetches

This is my first sketch, that includes my concept and some inspiration. 

So I want to create a friendly robot, using camera for motion, digger for meaning and metal for material. 

I am not completely sure about the story, but here are some of the ideas: 

1. it's in the trash yard and it's body is not complete. So it's looking for it's missing parts and fixes itself. And the conflict could be about troubles of doing it with only one hand (cause the other one is missing) or it is hard for it to search for it's details cause one eye is missing or some parts on an eye (like a lens) and it cannot see well.

2. The robot is lonely and bored and it looks for details and creates a boyfriend/ girlfriend or just a friend for itself.

3. Or it could construct itself a baby, so it could be a sweet baby-father story. (for some reason I see it as a male - father, not mother-robot).
