Drones are unmanned aerial vehicles, also commonly called UAVs. A UAV is an airplane that does not have a pilot to operate it but uses software instruction to perform necessary tasks. The basic function of a drone is industrial data collection as well as military data collection. Drones are used for aerial surveys, pipeline inspection, etc.
Operation of a Drone
Drones use software instructions for operation and are governed by a human operator on the ground. The operator sends software instructions to the computer installed inside the drone using Radio Frequency signals.
Drones use two types of sensors:
- Sonar sensors: These generate sonar energy pulses and trace echoes. Only one reading can be saved in this type of sensor. This reading can be retrieved or overwritten.
- Teledensitometer sensors: These generate readings continuously and are stored in a temporary buffer. The operator can delete the existing data, archive the data and add new data.
Example of a Drone Operation
Industrial radio controlled drones can used to locate oil on the sea floor. They collect data from the seabed using sensors. The operators send instructions to the Drone, which command them to move over the sea floor, communicate its position using GPS, gather information, take measurements, pictures, etc. The collected information and calculations are sent back to the operator using software instructions for further processing.
Drones also find many other applications in the scientific research, civil and military applications. They are very useful in instances where the application poses a threat to the human life.
