3. Outline Problem Solution Constraints Technical Practical System Overview Design Changes System Testing Remaining Tasks Q&A

4. 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 Problem Dog owners are beset by numerous difficulties [1]

5. Market Solutions 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

6. 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.

7. Technical Constraints NameDescription Battery Life The battery life of the collar must be at least thirty six hours 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.

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

9. Practical Constraints Practical Constraints Ethical 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

10. Practical Constraints 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

11. System Overview

12. Design Changes Collar ● Microprocessor changed from Arduino Micro to PIC33 ● 7kHz filters replaced with RF transmitter/receiver pair ● Improved antenna

13. Design Changes ● Added DC biasing ● Output current amplified using power transistor ● Adjustable current Fence

14. Design Changes Microprocessor changed from Arduino Micro to PIC33 Servos motors changed to linear actuators Wire loop changed to RF transmit/receiver pair and IR proximity sensors Door
