This research introduces Saranga, a novel ultrasound-based perception system for palm-sized aerial robots. By cleverly leveraging ultrasound, the system allows these tiny robots to navigate even in visually degraded conditions, like fog or darkness. The use of deep learning for noise reduction is particularly exciting, promising a robust and reliable navigation solution.
Key Takeaways
- •Saranga utilizes ultrasound, similar to how bats navigate, for obstacle detection.
- •The system uses a deep learning-based method to filter out noise, enhancing performance.
- •This technology allows small aerial robots to navigate in conditions where cameras and LIDAR fail.
