Band on the Run

The goal of the project is to work with the Mechanical Engineering team to create a platform for the band members to use during half time shows.

=Problem Definition= Our Band on the Run project was previously known as the BandBeetsen Project. There have been many changes throughout BandBeetsen's life time. This year we were tasked with creating a whole new platform for the University of Idaho marching band members to use during performances. While the Mechanical Engineering team was tasked with building the platform itself, our goal was to create an electrical system that allowed the platform to be controlled by a RC controller.
