1. helicopters

   A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most common helicopter configuration. However, twin-main rotor helicopters (bicopters), in either tandem or transverse rotors configurations, are sometimes in use due to their greater payload capacity than the monorotor design, and coaxial-rotor, tiltrotor and compound helicopters are also all flying today. Quadrotor helicopters (quadcopters) were pioneered as early as 1907 in France, and along with other types of multicopters, have been developed mainly for specialized applications such as drones.

   Right now natural parks have two big problems, the first one of them is to detect rhinos and non-authorized people in the area. That has been done with helicopters and planes up until now, but that is very expensive. In addition, you cannot see people who hide under trees from a plane. We solve this with thermal cameras. We use a drone that carries that kind of camera and looks over that area or those places suspected of having this kind of problem and it detects hot points. Like we see here. This shows people. Every pixel has a different color depending on how hot it is. This is placed on the drone, that takes a picture and reports directly to the ranger.
