Abstract: This technology relates to a system for clearing a sensor cover. The system may be comprised of a first sensor that rotates within a sensor cover, a plurality of second sensors that are fixed relative to the sensor cover, a first wiper that is configured to clear the sensor cover of debris, and a motor. The motor may rotate the first wiper in a first direction at a first predetermined rotation rate defined at least in part by a second predetermined rotation rate of the first sensor.

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 movable 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.

Abstract: Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal from a position sensor indicating a current position of the sensor housing may be received. A second signal to activate a liquid nozzle and an air nozzle, the liquid nozzle being configured to provide a spray of liquid and the air nozzle being configured to provide a puff of gas may be received. When to activate the liquid nozzle in order to provide the spray of liquid on the sensor input surface may be determined based on the current position of the sensor housing and the second signal. When to activate the air nozzle in order to provide the puff of gas on the sensor input surface may be determined based on the current position of the sensor housing and the second signal.

Abstract: Aspects of the disclosure relate to systems for cleaning a sensor. For example, the sensor may include a housing as well as internal sensor components housed within the housing. The housing may include a sensor input surface through which signals may pass. The system may also include a motor configured to rotate the internal sensor components relative to a mount as well as the mount to which the motor is fixed. The system may also include a wiper including a wiper blade. The wiper may be attached to the mount such that rotating the housing causes the wiper to contact the sensor input surface in order to clean the sensor.

Abstract: Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal indicating that there is a contaminant on the sensor input surface may be received. In response to receiving the first signal, a second signal may be sent in order to cause one or more transducers to generate waves in order to attempt to remove the contaminant from the sensor input surface.
