Israel might be a mecca of start-ups but it is also very well known for its military technology. Israel Aerospace Industries (IAI), known worldwide for their commercial aerospace technology has given a demo of butterfly-shaped drone that will not even let the enemies know what they are dealing with. The drone, which is more of the size of a moth is expected to play a strategic role in determining where the enemy is hiding. Weighing at a mere 20 grams, the four-winged butterfly can flap its wings up to 14 times per second. Surprisingly, what amounts to 15 grams of its weight is a camera and a memory card.
What makes this one a legendary drone is its ability to fly in enclosed environments such as office buildings, airport terminals etc. You don't really need to run after your enemy in battlefield as this secret information agent could follow the enemy and keep track of his location. The control to this miniscule drone is embedded in the soldiers camera who can see through the "eyes" of the butterfly.
The organization has also come up with the versions of technology that could help in city patrolling, especially in cases where bombs are implanted by enemies secretively. The two creatures employed for this purpose were a ghost, weighing 4 Kgs and a mosquito, weighing just 500 grams. We do expect the size of such drones to drop significantly with time, which should be a cause of worry for the enemies.
