    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.

    Abstract: The disclosure provides for a wiper system for cleaning a surface of a sensor housing, such as a sensor housing positioned on top of a vehicle. The wiper system includes a plurality of windows spaced around a sensor housing, and a plurality of wipers positioned around the sensor housing, each of the wipers includes a wiper blade configured to clean a corresponding window of the plurality of windows. The wiper system further includes a drive system including a moveable part coupled to a motor. The motor is configured to drive the drive system to simultaneously rotate the plurality of wipers around the sensor housing such that the plurality of wipers remove debris from the plurality of windows.
