The team plans to create a prototype that exemplifies the entire Automatic Aquarium Water Changer. A basic assembly drawing of the system is shown below. The system is composed of two pumps, an electronic housing unit, tubing, and two reservoirs.
The prototype shown above will validate our engineering analysis through testing the pumps at different operating heights to try to gauge the optimal range of heights that the pumps need to be placed at. Also, we hope to verify the theoretical plots shown in the Engineering Update, because if we can accurately predict the time required for water removal/filling, we will be able to encode the Arduino accordingly to satisfy the problem statement.
Below is the group's Bill of Materials including all procured components.
Below is a video of the complete Automatic Aquarium Water Changer in action. It takes out 20% of 10 gallons and puts back in the same amount of water.
