Objectives of the Robot:
Score as many points as possible in 60 seconds.
Points scored by obtaining game pieces (cubes and balls) from one location and depositing them at other locations.
Fig: Playing Field and Attempted Game Piece Locations.
Responsibilities:
Designed and fabricated the drive train and base of the robot.
Created overall CAD assembly of individual subassemblies designed by teammates in Fusion 360.
Created engineering drawings of drive train and base subassembly.
Carried out theoretical analysis to find maximum mass that can be transported by the drive base with the available torque from two geared motors.
Wrote reports on robot design, fabrication, theoretical analysis, and performance.
Overall fabrication of robot using drill press, laser cutter, and 3D printer in machine shop.
With another teammate, created a CAD animation of our working robot for use in the robot presentation.
Collaborated on design and manufacture of scooper component.

Analysis (See Robot Report below for details):
Fig: Derived Equation for the Maximum Mass that can be transported by the drivetrain.

Fig: Free Body Diagram for Robot Base/Chassis
A FOS value of 4.2 for the mass to be transported by the drivetrain was found after analysis. This means that the drive base is able to transport up to 4.2 times more mass than it is actually required to transport.
