Rotating blade mechanism for cleaning cylindrical sensors

This invention describes a system to keep optical sensors clean. It uses a motor to spin a set of nozzles around the sensor, spraying compressed air to clear away debris. In some versions, the sensor itself also spins, and additional nozzles can spray cleaning liquid.

Why it matters: The increasing reliance on optical sensors in autonomous systems and advanced robotics since 2022 has amplified the need for robust, automated cleaning solutions. This design offers a mechanical approach to maintaining sensor clarity, which is critical for these evolving applications.
