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.

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.
