We introduce the hardware system and the observational results of the
Automated Response Telescope. The current system consists of two 0.35 m
telescopes located in Toyonaka, Osaka, Japan.Each telescope is equipped with a filter wheel and optical CCD
imager. Once a gamma-ray burst position is reporetd through the GCN
(Swift, HETE) or the IBAS (INTEGRAL), automated imagingof the burst location is started within a few minutes. We will present the
current operation status, observational results, and future prospects.
