2. Introduction Purpose: – Create an intercollegiate football competition. – Prototype a robot that might be a player. Market: – Engineering Students. – Engineering Professors. – Prospective University Students.

3. Design Requirements - Competition Contest Length – 20 min. Game / 5 min. Quarters Field Dimensions – 8 ft. x 15 ft. Players on the Field – 4 Robots per Team Length of a Single Play – 15 sec. Size of Object of Play – 2 in^3

4. Design Requirements - Players Robot Size – 1 ft^3. Robot Weight – 7.5 lbs. Power Source – 9V Robot Controls – Suitable for ages 12 and up.

5. Our Concept Competition Rules – Autonomous Game Play – 4 downs to mid-field, 4 more to score – Velcro covered ball – Offense: Running Plays Passing Plays – Defense: Prohibit Reception Tackle Player with Ball Cause Fumble

6. Our Concept - Quarterback Key Features: – Throwing Arm Directly driven by motor Throw up to 3 ft. – Rotating Base Turn over 180 degrees

7. Our Concept - Receiver Key Features: – Drive Wheel Speed Control – Wheel Odometry Accurate within a half rotation

21. Future Feasibility of Concept Can throw and catch in a straight line – GOAL: be able to run turning routes. Can throw up to 4 feet – GOAL: able to throw 5-8 feet. Current quarterback is immobile – GOAL: mobile quarterback. Current robots are functional – GOAL: humanoid robots.

22. Future Feasibility of Concept Robots don’t communicate – GOAL: communication between robots to increase accuracy. All open-loop control – GOAL: sensors to aid in catching and obstacle avoidance. No defensive robots – GOAL: defensive robots with vision to find offense. Buttons on each robot to call and start play – GOAL: coach remotely calls and starts plays.
