I had the same problem earlier but when I replaced my battery with a maxwell 3v battery it worked
What does the motor do when you attach it to a AA battery?

The motor will start spinning but at very low rpm
Funny. You are probably too young to have ever seen an actual pager in commercial use other than the ones they use in restaurants. I wonder how long we will keep calling them "pager motors" since these are mostly used in other devices now. It's kinda like how we still refer to recording something as "taping" something. Rarely is anyone storing data on tape. I digress.

I made my first vibrobot this weekend with a similar design. My brush was too skinny to remain standing so I hotglued a three inch piece of solid core wire across it to act as "legs".

ALSO, I used a tiny magnet on top of the battery for holding the wire down instead of foam tape. Works like a nice switch . As a bonus, I can stick my bot to the filing cabinet when not in use.

A nice reproduction of a classic Make.
