Robo-AO is the first autonomous laser adaptive optics system and science instrument operating on sky. With unparalleled efficiency, the system is observing every Kepler planetary candidate host star (KOI) in search for previously unkown nearby stars that Kepler was unable to resolve. These nearby stars dilute the observed planetary transit depth, leading to underestimated planetary radii, or, in some cases, are the source of a false positive planetary transit signal, such as a background eclipsing binary star system.
