Disposable drones protect forests from fires
When it comes to drones, we immediately imagine a high-tech quadrocopter or military drones. But there is a more primitive devices, such as the ones that created the company Robotics.
A team of engineers led by Paul Pounds from the University of Queensland (Australia) has developed a couple of drones single use – in the literal sense of the word. One is made from paper and the second shape has a maple seed. Both simple and inexpensive to manufacture. The devices are designed to save lives in the event of a forest fire.
Tiny drones are equipped with various sensors of the environment, which alert the rescue services on changing weather conditions, which may indicate the spread of fire.
The first device looks like a normal paper airplane, but it is made of a biodegradable material based on cellulose. Being thrown from a larger aircraft, the so-called Polyplane continues to move in a given direction. Board control system directs the drone as close as possible to the place of landing.
The benefits of disposable UAVs are obvious. They are light, cheap, have good aerodynamic performance and do not harm the environment, because after the job decompose under certain conditions. All electronic components are applied to the printed circuit board blasting.
The second prototype, simulating a helicopter is called Samara. It is made of such a biodegradable material. Samara less controllable than Polyplane. Because of its design, the machine rotates in the air like a maple seed, slowly landing on the ground. The obvious advantage here is no need to install an expensive system of planting.
Meanwhile, the Germans are hoping that drones will protect them from vandals railways.
