For the MAE 277 reverse engineering project, our group was given two electric
powered RYOBI corner sanders (Model #’s P400 & CFS1502). One of the sanders
is powered by an electric cord and the other is battery-powered. Throughout the
semester, we will be dissecting and analyzing the components that make these two
products work. We will then compare the different results for the two sanders to
figure out which one is more efficient than the other.
