  We analyze observations from Robo-AO's field M dwarf survey taken on the 2.1m
Kitt Peak telescope and perform a multiplicity comparison with Gaia DR2.
Through its laser-guided, automated system, the Robo-AO instrument has yielded
the largest adaptive optics M dwarf multiplicity survey to date. After
developing an interface to visually identify and locate stellar companions, we
selected eleven lowsignificance Robo-AO detections for follow-up on the Keck II
telescope using NIRC2. In the Robo-AO survey we find 553 candidate companions
within 4" around 534 stars out of 5566 unique targets, most of which are new
discoveries. Using a position cross match with DR2 on all targets, we assess
the binary recoverability of Gaia DR2 and compare the properties of multiples
resolved by both Robo-AO and Gaia. The catalog of nearby M dwarf systems and
their basic properties presented here can assist other surveys which observe
these stars, such as the NASA TESS mission.
