Overview Project Task Main Objectives Robot Details Movement Collection Detection Outdoor Considerations
Main Objectives Autonomously move around a tennis court in order to collect tennis balls. Must be able to find, track, and collect tennis balls. Must have an easy way to take tennis balls from the robot. Must not interrupt the game. Must be fully operational in outdoor conditions
Movement Currently considering two drive wheels and one caster. Ideally the robot will only operate on the court itself, which is even terrain. Also considering 4WD and treads. Helpful for courts that are not 100% contained (grass borders)
Collection Needs to be able to collect tennis balls while moving. Currently considering a mechanism similar to those used on driving ranges.
Detection Originally considered a CMU camera to detect tennis balls. Reservations: Finding a green ball on a green court Variations of outdoor lighting makes this inconsistent Currently considering IP camera for blob detection and temperature sensors. To keep from interrupting games, will add a photodiode to detect white lines.
Outdoor Considerations Sunlight Need to protect components from direct sunlight. Need to keep lighting conditions for photodiode consistent. Rain Components need to be protected from rain and post-rain conditions.
