2. Project Proposal #1: IR Sensor System for Aquatic Neurobehavioral Research • Power Supply, IR Transmitter, IR Receiver, Filter, Feeder System, Microprocessor, RS232 Port • Project is designed to test the effects of positive reinforcement in a controlled habitat for fish. Upon the visual stimulus of a green light, the fish will be prompted to cross the infra-red barrier releasing the food at the opposing end of the tank. • Advantages of Project for Team #4: • Previous research and experience in optics • Prior microprocessor design and buildup • Knowledge of control devices

8. Selection Matrix – Average team scores 0-100

9. Project Selection • Overall Selection Process • Project Advantages: • Provides an opportunity to design a product based on customer requirements • Project will be funded up to $1000 • Design will utilize strengths of team • Project will be original and free from competitive market • Project Risks: • Potential for design conflict of interest • Working prototype must be within tolerances and design specification as it will be implemented in customer’s research

10. Project Selection • Overall Selection Process • Rejection Process • Previous projects proposed did not support the necessary amount of blocks required • Projects rejected did not offer the challenge or complexity for senior design • Initial ideas had been previously attempted by senior design groups at other colleges • Team Decision • Team completed the selection matrix and chose to move forward with the design of the Fish Tank Apparatus • Team unanimously agreed on the selection of the final design

11. Proposed Product: IR Sensor System for Aquatic Neurobehavioral Research • This product is designed to assist in the research of neurobehavioral studies of fish, through the use of positive reinforcement • Project will be used to collect data for study at the Great Lakes Institute • System will serve as a training device that will record data used to identify neurobehavioral activity of fish • The project will be the first attempt to collect data for aquatic neurobehavioral studies • No known products are currently on the market • This product is developed for use in water and marine research
