Band-Beesten 2014

This is the continued interdepartmental effort to both create a fully mobile drum set for use by the Vandal Marching Band and market the efforts of the University of Idaho's Mechanical Engineering Department. Current design goals for the Band-Beesten focus on decreasing weight and Omni-ball friction while allowing for a wider variety of instruments to be used, as well as market the work done by the engineering team by creating a video to show off the UI Marching Band.

Background
The original idea for the project began a few years before the Fall of 2011 by Dr. Edwin Odom, Professor of Mechanical Engineering, and Dr. Daniel Bukvich, Professor of Percussion and Music Theory. The plan was to collaborate between their disciplines and create a finely tuned, expertly engineered drum set that is fit for a full on-field marching band performance.

The Fall of 2011 marked the initial experimentation and design of the Beest by a Capstone Design team in the engineering department. These initial tests provided insight on what worked well and what needed improvement. The final design from this year was never seen outside of the engineering buildings on campus, but the following year's goals were clear and a new design began immediately. For more in depth design details refer to the Team Drum Roll webpage.

The Fall of 2012 marked the first public introduction of the Beest, which has become a yearly project in the Capstone Design process. Dan Mathewson, a University of Idaho graduate student, designed and utilized a robotic, power driven front wheel that responded to the drummers input and included brightly lit led's on the forward facing drums. It successfully astounded the audience and fulfilled the requirement of marching with a wheeled drum set, but it could still be improved. Dan's thesis can be found in the References section.

The Beest was successfully used during the last two home games of the 2013 football season with the new omni-wheels working as intended. The future of the project will entail designing a lightweight, efficient frame that can be easily dismantled for easy storage by the marching band as well as creating a stop-motion video of the halftime show using Lego to be used for marketing purposes.

First Semester

 * Create a mobile drumming platform to be used in time by the UI Marching Band in its last two halftime shows.
 * Drumming platform must be able to move in any direction easily solely from drummer input.
 * Drumming platform must carry at least 6 different instruments to out-show the quad drums.
 * Create a Txalaparta and four mallets to be used in time by the UI Marching Band in its last two halftime shows.

Second Semester

 * Re-design the chassis for the Band-Beesten drumming platform to be lightweight and collapsable.
 * Create a marketing video for the UI Marching Band featuring the Txalaparta and Band-Beesten out of Lego.
 * Create 3D printed models of each instrument used by the Band and recreate the UI halftime show out of stop-motion Lego.

Frame Design

 * Problems from 2013:
 * Omni-wheels were designed for very specific ball size; large balls got stuck, small balls slipped out
 * Basketball needed to be refilled prior to every performance to prevent slipping out
 * Wood frame was unable to rigidly hold all instruments securely
 * Assembled Beest was too heavy due to extraneous supports, electronics, and non-ideal frame design.
 * Improvements for 2014:
 * Re-design the frame to allow for a wider variety of instrument use
 * Frame needs to be easily collapsible for storage
 * Frame needs to be at least 20% lighter than previous incarnation
 * Omni-Ball frame should be reworked to allow for a wider variety of ball size
 * New attachment method for Omni-Ball assembly to reduce weight and increase stability
