  As part of our multi-observatory, multi-filter campaign, we present \rmi
color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR
instrument on the 1.5m robotic telescope at the San Pedro Martir's National
Observatory in Mexico. Our project is particularly focused on rapid response
observations of small ($\lesssim 850$ m) NEOs. The rapid response and the use
of spectrophotometry allows us to constrain the taxonomic classification of
NEOs with high efficiency. Here we present the methodology of our observations
and our result, suggesting that the ratio of C-type to S-type asteroids in a
size range of $\sim$30-850m is 1.1, which is in accordance with our previous
results. We also find that 10$\%$ of all NEOs in our sample are neither C- nor
S-type asteroids
