What are the wheels on a bulldozer called?

Question

I want to build a small little robot that looks like Wall-E (Don't give me any robot advice I know what I am doing) and I saw the movie yesterday, and saw that he has those wheels like a bulldozer, not just regular car wheels or little toy round wheels that I can buy anywhere. Where can I buy small wheels like that? Radio Shack? What are they called? Like, what would I type in the search bar to find the wheels? Thanks!

Answer 1

They're called tracks. There are many remote control toys with them. Radio Shack should have something you could use.
