Team 12, Iron Man, has decided to design and build an off-road capable running cart that can be easily collapsible and transported. For this design, the team will make the vehicle as light as possible while maintaining the necessary strength to carry a teenage passenger. The team has specifically designed the running cart with a disabled passenger in mind. The important aspects for this design that needed significant engineering focus were the collapsibility, quick-wheel change, overall passenger comfort, and maneuverability of the running cart. The team will also attempt to make the design as inexpensive as possible for future manufacturing and business possibilities. Through the research and analysis presented in the Project Proposal and Feasibility Study (PPFS), Team 12 has concluded that creating an off-road running cart is feasible.
