Dr. Braude from the Biology department at Washington University in St. Louis is currently working on a project training giant Gambian pouched rats to find mines and other bombs in former conflict zones. In order to trap Gambian pouched rats, Professor Braude asked a few MEMS 411 Senior Design groups to design and build a trap that can safely capture the rats. The trap had to be about 2-3 feet long, 6 inches in diameter, completely mechanical, simple, and it had to cost less than 30 USD to build.
