Show moreThis IPRO is the second of a two phase design project. Its objective is to continue the work of the Summer 2004 IPRO 332 team, advancing from feasibility study and conceptual design to prototype development. This IPRO will focus on the specific material selection and design specifications of a successful prototype that meets the following design objectives: low cost, easy to use, easy to produce, and meets the requirements outlined in the research studies. The finished prototype will then be sent to La Crosse Exercise and Health Program at the University of Wisconsin where the effectiveness and safety concerns will be addressed. Show less
