The RAT may be used on rocks that have a relatively flat surface with an area of at least 10 centimeters in diameter on which to place the RAT. However, there are many factors that the engineers from Honeybee Robotics (makers of the Rock Abrasion Tool) need to consider in order to determine the “RATability” of a rock. In addition to the size of the spot on the rock to be RAT’ed, engineers must consider the overall size and width of the rock, how well it is seated on the ground, the roughness and expected hardness of the surface, and a host of other factors.
