Abstract
This technology relates to a system for clearing a sensor cover. The system may be comprised of a first wiper and second wiper configured to clear the sensor cover of debris and a motor. The motor may rotate the first wiper and the second wiper in a first direction at a first predetermined rotation rate defined at least in part by a second predetermined rotation rate of a first sensor arranged within the sensor cover. The first wiper and the second wiper may be offset by a predetermined angular distance relative to a center of the sensor cover.
