Rotating Radio Transients were discovered in 2006 as a result of data mining of the Parkes survey for transient objects. The 11 Rotating Radio
Transients (RRATs) seem to be a unique class of pulsars which burst for short periods and when in outburst can be among the most radio-bright objects in the sky. The place these objects occupy in the evolution of pulsars in still an active area of investigation. We report here one of the first attempts to identify optical counterparts to RRATs. The data were obtained with the 0.4m robotic PROMPT telescopes during automated observing. Our data consists of VRI and I-band imaging of three RRATs, J144360, J13175759 and J084843. While several candidate variable stars
seem to be present in the data, we did not detect any transient sources coincident with the RRATs.
