  Observations of the prompt afterglow of Gamma Ray Burst events are
unanimously considered of paramount importance for GRB science and related
cosmology. Such observations at NIR wavelengths are even more promising
allowing one to monitor high-z Ly-alpha absorbed bursts as well as events
occurring in dusty star-forming regions. In these pages we present REM (Rapid
Eye Mount), a fully robotized fast slewing telescope equipped with a high
throughput NIR (Z', J, H, K') camera dedicated to detecting the prompt IR
afterglow. REM can discover objects at extremely high red-shift and trigger
large telescopes to observe them. The REM telescope will simultaneously feed
ROSS (REM Optical Slitless spectrograph) via a dichroic. ROSS will intensively
monitor the prompt optical continuum of GRB afterglows. The synergy between
REM-IR cam and ROSS makes REM a powerful observing tool for any kind of fast
transient phenomena.
