Last year, a group of 5 or so brothers in my fraternity competed in Build 18, and created a driving fish tank that was driven by our house goldfish (Scuba Suresh). The tank moved based on the location of the fish in the tank. The used a sensor mounted above the tank to determine the location of the fish. The further the fish moved to the forward determined the speed at which the motor propelled the tank. The tank would also turn based on the fish’s location right or left of center. Although it look minimal software and hardware, I took it as an inspiration because it was a quirky use of their knowledge and they were able to create it with a close group of friends. They actually became quite the internet sensation when the video when viral on Facebook, receiving half a million likes overnight.
