2. Project Description Robo-Football Demonstration and Competition Development Intercollegiate robotic “football” competition with elements similar to American Football Will develop rules and quarterback prototype to demonstrate some key features of the game

3. Previous Week’s Action Items Item 1 : Finalize Prototype Design – Motors for wheels and cam – Wheel type, size, and orientation – Robot housing geometry Item 2: Order Parts for Prototype – Order material for robot housing – Order necessary wheels/casters – Order motors for wheels and cam

4. Driving Mechanism Design Wheel Configuration 8” Diameter Wheel for Differential Steering 1.5” Diameter Caster for Stability

5. Considerations for Motor Selection

6. Impact of Cam Design Design VariableValue (units) m6 in. f2 7/64 in. yoyo 5 o L30 o RbRb 2.6323 in. Source: AME 40423 Course Notes Sec 7.2.1

7. Current Status Current Graphic – Completed CAD drawings and assemblies of prototype parts Design Status – Finalized prototype dimensions – Material and wheels ordered and arrived Schedule – Show Stopper: Have not selected motors for wheels and cam

8. Current Graphic CAD assembly of the air cannon

9. Next Week’s Action Items Item 1: Finish CADing Prototype – Already completed cannon and housing – Finish other parts – Create assembly of prototype Item 2: Build air cannon – Cut and sand parts – Cement parts together
