Abstract
The MITSuME robotic telescope system for optical/IR follow-up observations of Gamma-ray bursts is presented. To detect the optical flashes, precursors, jet-breakouts and the other intriguing phenomena related to GRBs, the telescope system is completely automated. To minimize the delay time of starting the observation, we had finely turned the control sequence. Currently the MITSuME can start an observation within a few tens of seconds after receiving GCN alert. In addition, we installed the "tiling observation mode" in the control system for the transient events discovered by Fermi and MAXI with low positional accuracy. We also summarize the highlight of the recent observations.
