As with many new technologies, drones were born out of the military industry. We could also quote the GPS, Internet to illustrate these transfers of industry, which then develops in the civil world.
If drones have been on the rise for a few years now, Its history is nevertheless rich and rather old. It was indeed more than a hundred years ago that the first specimens were born, towards the end of the First World War. Research continued during the following decades to become more democratic in the early 2000s, and thus leaves the military fold.
Things to Consider When Building Your Own Drone
Making your own drone is no longer a challenge. While it is quite conceivable to make civilian drones yourself, it is essential to have some knowledge in the matter and/or to get help. Choosing the right equipment can prove to be a rather long step and strewn with pitfalls. Some, on specialized sites, even recommend buying a drone kit, easy to assemble. It seems like a simple introduction to familiarize yourself with the different components of drones. This will permit you to create a development venture that will be closer to your starting objective.
The essential elements to assemble
To make a drone relatively easily, you need to precisely design the item you want to get. Is it a mini-drone? A terrestrial drone? A drone dedicated to aerial photography, with an on-board camera? The very function of the object will determine all the elements that compose it. For example, the size of the rotor, leads to the choice of a motor of a certain power, therefore more energy to be produced and thus the installation of a sufficiently powerful battery.
Besides and anything your project, the make of a drone remains an forced figure or certain components are fundamental. We will discuss here the different materials that will undoubtedly be at the heart of the manufacturing process.
The chassis is the central element of the device since it is this which will support all the parts, but it is also this which will give the drone its final shape, through its design. In most cases, the frames are made of aluminum or carbon fiber, which gives them the double advantage of being both light and stiff. In the case of an aerial drone, this is an essential aspect. A light drone will see its performance improved.
Here once more, the choice is specifically connected to utilize you’ll make of your drone. The engines will have to combine power, lightness, consumption and in some cases speed. At the same time, other elements will necessarily be added: the propellers and speed controllers (ESC). The propellers are an extension of the engine, so they should be chosen with care. The speed controllers analyze the information from the flight controller. It is necessary to have one per engine.
This is the element that will determine the autonomy, more precisely the flight time for aerial drones. Most often these are LiPo (lithium polymer ion) type batteries. The determining characteristics for choosing the right battery are voltage, weight, rate of discharge and capacity.This last point is important, because it is the flight time, which is at stake. The greater the capacity, the greater its weight will be, which will have a direct impact on the stability of the assembly.
The flight controller
This is a central aspect in the development of the drone. Depending on the quality of the product, it will be more or less capable of relatively complex actions. Respecting a flight plan established in advance, automatic landing, performing figures, managing a camera are concrete examples of the different potentialities of these controllers. They are also closely linked to the type of drone chosen (plane, helicopter, etc.). This element can be considered to be the brain of the drone. If you specialize in electronics it is possible to modify the programming to improve, refine its capacities and thus develop its options.
The radio control
Capital element since it represents the link between the drone and its pilot. Piloting a drone is still the best time for aficionados. The radio control is composed of a transmitter box and a receiver placed directly on the drone.
The Internet is full of sites and tutorials dedicated to the design of drones. By searching a little it is quite possible to come across an expert who will detail the assembly in its technical dimension.
Some generalities on drones
There are three main families of drones depending on the environment in which they operate.
- Land drones (demining, fire fighting, weeding, chemical risk detection, camera drone, etc.);
- Maritime drones (research, interventions on underwater installations, etc.);
- Aerial drones (submerged flight, shooting, etc.).
Depending on it drones features will change from one to another. But there’s always key features those are mentioned above. With this you can have a basic one.
