  Planet population synthesis models predict an abundance of planets with
semi-major axes between 1-10 au, yet they lie at the edge of the detection
limits of most planet finding techniques. Discovering these planets and
studying their distribution is critical to understanding the physical processes
that drive planet formation. ROME/REA is a gravitational microlensing project
whose main science driver is to discover exoplanets in the cold outer regions
of planetary systems. To achieve this, it uses a novel approach combining a
multi-band survey with reactive follow-up observations, exploiting the unique
capabilities of the Las Cumbres Observatory (LCO) global network of robotic
telescopes combined with a Target and Observation Manager (TOM) system. We
present the main science objectives and a technical overview of the project,
including initial results.
