Drones are unmanned aerial vehicles that can either perform autonomous flights along a specific route or be remotely controlled by an operator remaining on the ground. You may have already noticed how much their popularity has grown in the last few years – over the past few years, these sales have grown by a staggering 180%, from 2.5 million devices sold in 2016 to a forecast of 7 million in 2020.
Such dynamic growth also contributes to the faster development of new technologies in this field, which means that newer and more interesting devices find their way to our markets, which makes it difficult to keep up with all the novelties. Therefore, we have divided the devices available on the market into three large categories, the advantages and disadvantages of which we discuss in detail:
Multi-rotor drones (most popular)
This is the most popular drone mode currently, eagerly chosen by both amateurs, hobbyists and professionals in industries such as photography, film production and property protection. We are happy to reach for it due to its small size and the possibility of using it almost right out of the box.
Multi-rotor drones are also the cheapest option in the drone world as they are the easiest to create for manufacturers. Depending on the number of rotors, they fall into even smaller categories: tricopters (three rotors), quadrocopters (four rotors, the most popular on the market), hexa- and octocopters (six and eight rotors, respectively).
Autonomous machines that, perhaps in the near future, will operate and make decisions without human intervention. In the most commonly used sense, drones are unmanned aerial vehicles. For years, they have been used mainly by the military, but the development of technology has made us observe their expansion on the civilian market recently.
The most popular, due to their piloting properties and ease of use, are multi-rotors, called quadrohex or octocopters depending on the number of rotors. Popular consumer drone models usually allow for a short flight of several or several dozen minutes and carrying a small load, such as a camera or a camera.
- the easiest to control and maneuver;
- have the ability to float in the air without moving;
- can take off and land vertically;
- they are very stable
- limited flight time (usually no more than 30 minutes); most of the battery power is used to overcome the force of gravity and stabilize the drone in the air.
Larger drones may be used commercially in the future as suppliers of pizza or various packages and goods.
Advantages of drones:
- Error tolerance in piloting
- Ease of use
- Low – in relation to the possibilities – price
- Drones disadvantages:
- Potential threat to privacy
- Risk of injury if the machine falls
- Limited use due to legal restrictions
