Little Mac II (3lb Battlebot)

This is the second version of Little Mac, now with a better weapon!

Just like the previous Little Mac, it is built inside an old Mac Mini computer, complete with the original Apple top plate.

It uses brushed drive motors, a Fingertech beater bar set, and custom circuitry. The weapon and wheels are on dead shafts, made out of old printer rods. The base is HDPE. All 3D printed parts are PETG.
