In 2010, former team member Eddie died of cancer. We have chosen to name our robot after him.

Technical Description
Eddie was designed to compete in
this year's FIRST Robotics Competition. What follows is a complete description of its mechanical workings, and the solutions our team created to overcome this year's challenges.
-
Eddie is capable of collecting foam basketballs from the floor using a belted roller mechanism at the front of the robot. This same mechanism transports the foam balls upward to the shooting mechanism. Balls are shot into goals via a spinning wheel shooter simmilar to those used by baseball and tennis ball auto-launching machines. The shooter is calibrated for high, close-range shots to maximize accuracy.
-
Eddie's drive train is a six-wheel, non-drop-center base powered by four CIM motors. One end of the robot has high-traction wheels to mazimize pushing power, whereas the other has omnidirectional wheels to increase turning ability.
-
Eddie is capable of traversing and balancing on the bridges that separate the field through the use of a wedge-like mechanism, known by team members as the flipticulator. The device is pneumatically extended outside the robot as Eddie approaches the bridges; from there, drivers need only accelerate toward the bridge, and the wedge will force it down, allowing Eddie to climb atop it.
