Which piece of equipment can help prevent a drone from colliding with objects?

A sense-and-avoid system is designed specifically to prevent collisions by using various sensors to detect obstacles in the drone's flight path. This system analyzes the surroundings in real-time, allowing the drone to make autonomous decisions, such as altering its flight path or altitude to avoid collisions with objects, people, or other aircraft.

In contrast, while a high-resolution camera might provide detailed visuals for navigation or recording, it does not actively prevent collisions. An extended range antenna helps with communication links but does not play a role in avoiding obstacles. Additional propellers may enhance stability or performance but are not directly related to collision avoidance. Thus, the sense-and-avoid system stands out as the most effective equipment for enhancing safety by minimizing the risk of collisions during drone operations.
