The drone has been used in many situations. Military drones are famous for the surveillance and bombing in Afghanistan and Iraq greatly reducing the human casualties. They are still being used in security provision through surveillance and sometimes attack. Some African National parks like in Botswana are using the drones to help protect the endangered species like the elephants and rhinos. The drones help in spotting and following up on the suspects while the wardens offer ground support. This combination seems to work as there has been reported reduction in poaching activities.
Drones are small unmanned helicopters of course with a few adjustments. Gradually, they are becoming more of toys and items of amusement for flying enthusiasts and the general public as the drones continue decreasing in size. There are so many things that drones can do. The following samples of drones capture the evolution quite well.
Eachine H8 is a mini Quadcopter. It acts as a precursor to the drone though it is more of a toy helicopter. It is controlled by a remote control within a 20-meter radius. It is quite a good flier- easy to take off and control. It can fly to a height of 30metres and for about 7 minutes thanks to its 150mAh battery. It not compatible with many other devices and is more of a simple toy. It has no camera nor many other features that are embedded in some more complex drones. It is however quite fast and may need one to do some good amount of practice before it can really soar.
Dobby is a drone from Zerotech company. It is a light machine, weighing around 20 grams. Besides a remote control, one can use a smart phone to control it. All one needs o have is an account created in the smart phone to get access to the control panel. This password helps in a way that it is not everyone to control it. The battery gives more flying time compared to the Eachine. At 940mAh it can last for a bit longer time and take photos and videos while flying. It has a 13 megapixels camera that comes with an image sensor. It is portable and can be pocketed to e used while taking ‘selfies’. The photos can be taken in many modes; it can be the single shots, continuous burst or short films. To take the photos, one can set the timer to 5, 10 or 20 seconds countdown or use the face re cognition to take the photos when one smiles. These images and films are stored in the inbuilt 16GB expandable memory. Dobby can be made to follow a person while taking photos or filming. This gives the controller the ability to take photos from different positions and angles. While flying, it acts as a wifi hotspot which enables the connection with the smart phone and Android devices. The images are seen on the screen of the smart phone. Though it has its down side, it still is a machine worth a try and quite an improvement of the quadcopter earlier discussed.
EhangGhost drone is a bit more complex than Dobby and the Eachine mini. It is considerably heavy, weighing in closer to a kilogram. The rechargeable battery gives it 25 minutes of flight in a kilometer range. It is endowed with a 13 megapixel camera and GPS for easy flight. It also has obstacle sensors and can easily fly in a place with few obstacles without accidents. All it needs is a Gbox which will help in controlling it. It can be connected to a VR headset and enables someone to view the images through the goggles. The photo angles can be controlled through a tilt of the head when wearing the VR headset. It can take both still photos and video transmitting them to the smart phone or internal memo. This is not yet the very best but sure is a pointer in the evolution that is the drone.
