Drones, for example, can be defined as unmanned aerial vehicles (UAVs) that are operated remotely or autonomously. Bees and HES are two examples of drones. Bees are small, four-rotor drones that are used for aerial photography and videography. HES stands for Hexacopter, which is a six-rotor drone that is used for more complex tasks such as search and rescue operations. Both types of drones are becoming increasingly popular due to their versatility and affordability.
