Abstract
A sensor assembly includes one or more sensors configured to collect data from an environment. A sensor window is disposed in a field of view of the sensor, such that the sensor senses the environment through the sensor window to generate sensor data. The sensor window is rotated relative to the sensor to cause obstructions on the sensor window, like water or debris, to disperse.
Claims20
A sensor system comprising:
- a sensor configured to generate sensor data corresponding to a field of view of the sensor;
- a sensor window disposed proximate the sensor such that the sensor senses an environment through the sensor window to generate the sensor data;
- and
- an actuator configured to rotate the sensor window relative to the sensor,
- wherein the sensor window is configured to rotate about a rotational axis that extends into the field of view of the sensor.

A sensor system comprising:
- a sensor configured to generate image data indicative of an environment;
- a sensor mount configured to fix the sensor to a mounting surface;
- a sensor window disposed in a field of view of the sensor such that the sensor senses the environment through the sensor window;
- a sensor window housing retaining the sensor window;
- a bearing positioned to facilitate rotation of the sensor window housing and the sensor window relative to the sensor mount;
- and
- an actuator configured to rotate the sensor window to cause obstructions on the sensor window to disperse from the sensor window.

A sensor cleaning system comprising:
- a sensor configured to generate sensor data corresponding to a field of view of the sensor;
- a sensor window disposed proximate the sensor such that the sensor senses an environment through the sensor window to generate the sensor data;
- an actuator configured to rotate the sensor window relative to the sensor;
- and
- a controller configured to perform operations comprising:
- transmitting a commanded speed for driving the actuator;
- determining a measured speed of the actuator implementing the commanded speed;
- and
- determining, based on a difference between the commanded speed and the measured speed, that the sensor window is obstructed.
