NASA's spacefaring humanoid robot needs help. Robonaut 2's vision is failing, because its sensors are old and had been affected by exposure to high levels of radiation in space. To solve the issue, the agency has launched a contest asking coders to create algorithms that will enable the robot to "see" better. R2 is currently serving as a helper/repair-robot of sorts aboard the ISS. It's in charge of managing the station's inventory using an RFID reader and does minor repair jobs, such as fastening loose bolts, to give astronauts more time for their experiments.
