GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, is an autonomous, solar-operated robot that carries a ground-penetrating radar to examine the layers of Greenland's ice sheet. Its findings will help scientists understand how the massive ice sheet gains and loses ice.
R2, which has been on the ISS since 2011, has a mission: clean handrails, vacuum air filters and take air-flow measurements. The problem is it doesn't yet have the ability to learn and complete the work. So NASA is looking for someone to teach the bot. The Robonaut Challenge calls on contestants to write algorithms that allow R2 to interact with a training dashboard the space agency built.
MSU scientists have made a number of improvements on the fish, including the ability to glide long distances, which is the most important change to date. The fish now has the ability to glide through the water practically indefinitely, using little to no energy, while gathering valuable data that can aid in the cleaning of our lakes and rivers.
