4. DRONAR: Obstacle echolocation using ego-noise
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. READ MORE
