Students who participated in the AT Devices - Service Learning project at CART gathered information on a physical disability. With this information they designed and built a prototype, or proof of concept, that would enhance or improve the physical modality of an individual with said disability or aid in the processing or manipulation of their standard environment. Several products were made and showcased including a glove that translated sign language into audio, an ergonomic walking cane, and a prosthetic leg for a dog. One project success was a bicycle attachment for a wheelchair. The students designed and built a hand-powered bicycle attachment that could fit to any wheelchair. Since the projects end, the group has been working on a second prototype as commissioned by a local physical therapist to be used in his practice.
