  The Southern Robotic Adaptive Optics (SRAO) instrument will bring the proven
high-efficiency capabilities of Robo-AO to the Southern-Hemisphere, providing
the unique capability to image with high-angular-resolution thousands of
targets per year across the entire sky. Deployed on the modern 4.1m SOAR
telescope located on Cerro Tololo, the NGS-AO system will use an innovative
dual-knife-edge wavefront sensor, similar to a pyramid sensor, to enable
guiding on targets down to V=16 with diffraction limited resolution in the NIR.
The dual-knife-edge wavefront sensor can be up to two orders of magnitude less
costly than custom glass pyramids, with similar wavefront error sensitivity and
minimal chromatic aberrations. SRAO is capable of observing hundreds of targets
a night through automation, allowing confirmation and characterization of the
large number of exoplanets produced by current and future missions.
