NXT Five Minute Bot
Sometimes you need a robot. Fast. Just to run an experiment, or as a temporary base to use to start another project. This simple NXT Five Minute Bot can be built in about 5 minutes (see boring video). It is reasonably sturdy and balanced, can turn easily on smooth floors, and has several basic attachment points for expansion. The building instructions will also work for the rechargeable battery pack as well as the AA batteries.
