Robo-AO is the first autonomous laser adaptive optics system and science instrument operating on sky. The system robotically executes large scale surveys, monitors long-term astrophysical dynamics and characterizes newly discovered transients, all at the visible diffraction limit. The first of many envisioned systems has finished over 100 nights of science observing at the Palomar Observatory 60-inch telescope (with over 13,000 robotic observations executed). The system will be augmented in 2014 with two new infrared cameras: a very high-speed, low-noise, tip-tilt sensor provided by U. Hawai`i and a 2 arc minute field-of-view camera, which can also double as a tip-tilt sensor, being developed jointly between Caltech and IUCAA. The new cameras will widen the spectral bandwidth of observations, increase available sky coverage, and enable deeper visible imaging using adaptive-optics sharpened infrared tip-tilt guide sources.
The Robo-AO project, led by Principal Investigator Christoph Baranec, with Software Lead Reed Riddle, Project Scientist Nicholas Law, Co-Investigator A. N. Ramaprakash, and students and collaborators, is a collaboration between Caltech Optical Observatories and the Inter-University Centre for Astronomy and Astrophysics. It is partially funded by the National Science Foundation under grants AST-0906060, AST-0960343 and AST-1207891, the Office of Naval Research under grant N00014-11-1-0903, by the Mount Cuba Astronomical Foundation, by a gift from Samuel Oschin and by the Indo-US Science and Technology Forum.
August 14th, 2014: "Astronomical instrumentation: Atmospheric blurring has a new enemy," by Brent Ellerbroek (TMT), describing Robo-AO's first large survey, appears in the current Nature News and Views.
August 4th, 2014: A press release titled, "Laser-wielding Robot Probes Exoplanet Systems," has just been posted which highlights two recent Robo-AO papers: one on the Robo-AO instrument and the first of our large survey papers, published in the Astrophysical Journal Letters (preprint) and the Astrophysical Journal (preprint) respectively.
July 15th, 2014: We're in the middle of our second of three summer observing runs with Robo-AO at Palomar. We're continuing to commission and integrate the infrared tip-tilt sensor with the Robo-AO software.
The July 2014 observing team: Dani, Christoph and Reed (in front of Robo-AO with attached infrared tip-tilt sensor).
June 27th, 2014: Robo-AO is at the SPIE Astronomical Telescopes and Instrumentation in Montreal, Canada with 5 talks and 1 poster that used Robo-AO data or technology:
June 13th, 2014: We're in the middle of our first of three summer observing runs with Robo-AO at Palomar. In addition to supporting science operations, we'll be starting to integrate the new low-noise infrared tip-tilt sensor we brought with us from Hawai`i.
The June 2014 observing team: Shane, Dani, Reed, Gina and Christoph.
May 1st, 2014: This summer, the Robo-AO project will be partnering with Disk Detective, a Zooniverse citizen science project to find dusty debris disks, the birthplace of planets, around stars. Robo-AO will be used to capture high-resolution images of stars with excess infrared light as identified by NASA's WISE mission. The Robo-AO observations will be critical in determining whether the excess light is caused by nearby background objects or actual debris disks.
March 3rd, 2014: Reed Riddle presented a talk on Robo-AO at the Optical Society of Southern California meeting on March 12th.
February 18th, 2014: Robo-AO's PI, Christoph Baranec, has been selected as a 2014 Sloan Research Fellow, based on the successful results from the prototype Robo-AO and plans for installing a facility version of Robo-AO on the University of Hawaii 2.2-m telescope.
February 14th, 2014: Christoph's Caltech Astronomy Colloquium, Scientific highlights from the Palomar Robo-AO system and plans for a Mauna Kea Robo-AO, is now online:
February 7th, 2014: High school senior Ganesh Ravichandran has been named a semifinalist in the 2014 Intel Science Talent Search Competition for his astronomy project, titled "Close Companions to Kepler Objects of Interest: Results from a Large Adaptive Optics Survey," which used data from our Robo-AO Kepler Planetary Candidate Survey.

January 7th, 2014: Robo-AO is at the 223rd meeting of the American Astronomical Society in Washington DC with 2 talks and 5 posters that used Robo-AO data or technology:
December 17th, 2013: We have submitted for publication the results of the first season of the Robo-AO Kepler Planetary Candidate Survey. This study represents the largest single adaptive optics survey to date and is just the beginning of our goal to observe every Kepler planet candidate host star to search for blended nearby stars, which may be physically associated companions and/or responsible for transit false positives.
The 53 Kepler planet candidates resolved into multiple stars by Robo-AO, 43 of which are new discoveries.
