Using bat anatomy to improve robot navigationSeeking a way to improve the navigational ability of robots, Colin Comard and his Expo team turned to the animal world — specifically the bat’s remarkable ability to maneuver quickly and precisely using sonar.

“Bats have specialized anatomy and biology that allow them to navigate with echolocation,” said Comard, who is getting a degree in electrical and computer engineering. “We’re trying to use that evolutionary advantage for our own robots to help them navigate better.” Continue reading

Cell phone photographs radiation, warns of dangerSophia Uchiyama and her Expo team have designed a small, inexpensive radiation detector which will enable anyone with a smart phone to “photograph” radiation and determine in a flash if they’re being exposed to high levels of radiation.

“We wanted something that’s easy to understand for people who are not trained in nuclear science, and which literally presents a picture of the radiation around them,” said Uchiyama, who will graduate next year with a degree in radiation physics after finishing coursework for a math minor.
