Seventy-five Johns Hopkins freshmen from an introductory mechanical engineering course will compete in this event. Twenty-six teams of two or three students have built devices that must be able to move along the floor and then launch a small projectile over a six-foot-tall barrier and strike a target. For a class project, each team designed a device powered only by mousetraps and rubber bands—no motors, no batteries.

Johns Hopkins student-built devices—a blood clot detection system and a concealable, hands-free breast pump—have won two of the top three awards in a national contest that recognizes innovative biomedical engineering designs that have high commercial potential and social impact.
In this competition involving freshman engineers’ inventions, batteries are NOT required – or even allowed. For a class assignment, 67 students from an introductory mechanical engineering course have built aerial vehicles that must move across elevated cables and drop a “payload” onto a bull’s-eye target five feet below. The challenge: these cable cars can possess no motors or batteries. All movement must come from mousetraps and rubber bands.
For devising a disposable suturing tool to guide the placement of stitches and guard against the accidental puncture of internal organs, an undergraduate biomedical engineering team from Johns Hopkins won the $12,500 first-prize Tuesday in the 2012 Collegiate Inventors Competition.
Three Johns Hopkins engineering students have won a $15,000 prize in a national sustainable development competition for adapting a traditional Korean paper-making technique into an inexpensive way for impoverished villagers to produce paper for schools.
On Wednesday, Dec. 1, 18 three-member teams of Johns Hopkins students in a freshman mechanical engineering course will compete on the Homewood Campus in a series of device races to deliver a “payload” past obstacles and across a finish line. Each device can only be powered by the energy stored in two mousetraps and six rubber bands.
