Arduino robot from flashlight body...

I've started with Arduino just recently and diving head first into a unique project of turning an old RadioShack flashlight into a robot.

Has anyone done anything like this? Do you have any references or advice?

I started a YouTube channel to document my progress and so I can get feedback and suggestions as I go along. Would love any Arduino experts to subscribe and make any recommendations as I move forward.
