As a mentor for 2.760, I supervised a team of graduate students working on a slope adaptable prosthetic foot in collaboration with the US Veterans Affairs. This class combines rigorous engineering theory and user-centered product design to create technologies for developing and emerging markets. It covers machine design theory to parametrically analyze technologies; bottom-up/top-down design processes; engagement of stakeholders in the design process; socioeconomic factors that affect adoption of products; and developing/emerging market dynamics and their effect on business and technology.
