Problem Solution System Overview Constraints Technical Practical System Testing Timeline Future Goals Questions

Incessant barking Jumping on visitors Using the restroom inside (assuming it is an indoor/outdoor dog) Tugging at the leash Running away Digging in the garden Dog owners are beset by numerous difficulties [1]

The Shock Collar Allows users to discipline their dog easily and quickly $30 - $260 Invisible Fence Shocks the dog via a shocking collar when it tries to cross the boundary $150 - $350 Dog Doors Allows the dog to enter or exit at its leisure [2][3] $170 - $1300

Our Solution Dog Collar Training Remote Invisible Fence Dog Door Our solution combines the three aforementioned systems into one elegant design. This system uses a single shock collar for all three applications diminishing the need for multiple collars.

NameDescription Battery Life The battery life of the collar must be at least one week and the battery life of the remote must be at least six months. Operating Range The remote must have an unobstructed operating range of at least 50 feet. Response Time The collar must respond to the training remote within one second. Size The collar dimensions must be smaller than 6x4x4 inches. Weight The weight of the collar must not exceed one pound.

The Ultimate Dog Collar must not cause excessive pain to the dog Ethical [4]

Vibrating motors are used over the more common shock Avoids the negative reputation of shock Has the same desired effect as the shock No pain

The collar must be tough enough to withstand the potentially rough behavior of dogs. Rolling Jumping Running The collar must be able to handle normal weather conditions. Wind Rain Dust Snow Environmental

7 kHz signal will activate buzzer and vibrating motors 10 kHz signal will open dog door Key Fob signal will activate vibrating motors 434 MHz Transmitter Vibrating Motors Buzzer Wire Loop Receivers Battery Life Indicator Key Fob Receiver Arduino Micro

Press and hold button, LED will turn on if circuit voltage is greater than 6.2 Volts

Main components are well below size & weight constraints Most components can be replaced with surface mount parts

Collar sends an “open” code to door Once the door receives the code, servos unlock the door Relocks after an allotted time
