Drones that make deliveries, a navigation algorithm for self-driving cars, using heat from a hydrogen fuel cell to keep food warm, small robotic vehicles that clean debris off roadways. These are some of the projects featured during a recent event at which ASU students exhibited and demonstrated designs and models of potential new technologies they’ve been developing. The projects gave students hands-on basic training in conducting research, reinventing older technologies, mapping paths to innovation, exploring ideas for new tools and systems and using their skills to serve the public good.
