This design group is focused on developing an device that alleviates stability and comfort issues which arise in walking distances, hiking, and jogging. Jogging or hiking is often impeded by relatively moderate degrees of instability. At the same time issues with stability and symmetry are well established in understanding injuries in athletes (Cavanagh et. al. 1977). The issues with stability are important for a wide range of people, including people who may be beginning an exercise regimen for weight loss up to elite runner. The goal of the system is thus not only to assist athletes with a wide range of physical abilities but also to help improve stability and symmetrical loading of joints to help all runners reduce their risk of injury. However, it it important that for all of these constituencies it is critical that the exercise should be enjoyable. Part of the enjoyment stems from equipment that is fun to use and aesthetically pleasing. The engineering principles associated with the project have a lot in common with bicycle design. Extensive use of material science and vehicle steering dynamics will be a part of the project. The application of these principles will be to a three-wheeled apparatus which is geared toward providing stability to a person while running.

The first year of the project resulted in a system which could be used in a race by Dr. Depoy. The new system needs to be smaller, have the ability to fold and should include intuitive active steering. The new system will need to be fabricated in a manner that results in custom bicycle quality build characteristics.
