Kwago Thermal Drone

A Filipino made “Search and Rescue” drone specialized for night operations was built by talented Filipino men and a finalist with the United Arab Emirates Drones for a Good Awards. The project code named “Kwago” is an app controlled drone equipped with a thermal imaging camera for heat signature readings from the ground, a pattern recognition software, auto take-off and landing AI (on case of collision), working sonar sensors and ads-b system, a fully packed search drone.

The project was patterned on how owls (Kwago) travels in pitch black with their sonars, adjusting the altitude or even velocity if needed to avoid collisions. This is a very neat feature specially the increase in risk with drones colliding with different aircraft. The sonar sensors enable Kwago to “see” these aircraft and in return enables the later to see the drone on their radar.
