WE PROPOSE TO BUILD A FULLY ROBOTIC WIDE FIELD (70 DEG2) OPTICAL TELESCOPE THE DECA-DEGREE OPTICAL IMAGER (DDOTI) IN SAN PEDRO MARTIR. THIS FACILITY WILL CARRY OUT A SYSTEMATIC FOLLOW-UP PROGRAM OF POORLY LOCALIZED FERMI/GBM GAMMA-RAY BURSTS (GRBS). IN ORDER TO FULLY EXPLOIT THE LARGE DATASET OF FERMI GRBS IT IS OF VITAL IMPORTANCE TO RAPIDLY PROVIDE AN ARCSECOND LOCALIZATION WHICH ENABLES EXTENSIVE FOLLOW-UP CAMPAIGNS AND REDSHIFT MEASUREMENTS. THIS EFFORT WILL BENEFIT THE ENTIRE GRB COMMUNITY AND GREATLY ENHANCE THE SCIENCE RETURN OF FERMI GRB OBSERVATIONS. THANKS TO ITS WIDE FIELD OF VIEW DDOTI WOULD BE OPTIMALLY SUITED TO FOLLOW-UP GRAVITATIONAL WAVES AND NEUTRINO SOURCES THUS COMPLEMENTING AND STRENGTHENING THE ON-GOING EFFORTS BY SWIFT AND RATIR.
