10 Amazing Robots That Really Exist

 op most amazing and coolest ROBOTS  The family of robot animals from the German developer of robotics Festo  is growing. The company presents many new robots, for example: a swarm  of ants that can interact with each other, as well as butterflies and  dragonflies, which are characterized by all the ease and grace of these  insects. When they were created, the company focused not only on their  appearance, but also on behavioral characteristics. The ants coordinate  with each other all their actions and movements. Each ant, that is  13-centimeter long, has on its belly a radio module, through which  precise coordination is carried out.  As for butterflies-robots. The weight of each butterfly is only 32  grams, this includes two servos, a pair of small batteries, and a  laser-made casing. After one charging that lasts fifteen minutes,  butterflies will be able to flutter for about 4 minutes. And their  flight looks very impressive. There’re not just butterflies, but a whole  system that consists of ten high-speed infrared cameras installed in a  room where butterflies fly. They track the infrared markers installed on  the robots, transmitting data in real time to the central computer; so  that’s how coordination of butterflies is going in the space. You can  hardly distinguish these bionic butterflies from the real ones in the  room where they fly.  Robotic seagulls and dragonflies that can fly just like their living  relatives. The seagull was developed in 2012. Later, a dragonfly, that  can hang in the air no worse than its natural counterpart was invented.  All the details of the dragonfly were made on a 3D printer, and you can  control this miracle with a smartphone. Through these developments, the  company could edge out the development market of flying drones, but it  doesn’t need it. The technology of flying and hovering in the air is  worked on these two prototypes. The kangaroo robot. At the core of the BionicKangaroo is the mechanism  of "recuperation" - it uses the energy recovered from one jump to help  it make another. Real kangaroos quickly got tired and could not jump for  a long time without this mechanism.   Springs that store mechanical energy on the landing and give it away on  the next jump are used in this project. BionicKangaroo that weighs 7  kilograms and highs one meter can make a jump of 80 cm in length and 40  cm in height. The power supply system, that forces it to move, is a  pneumatic accumulator. The robot is controlled by a special bandage that  reads myoelectric signals from the human forearm.  Robot shark. This unmanned underwater facility - a robotic shark length  of about one and a half meters and weigh up to 45 kg. Like a real fish,  the robot uses the tail to move and control its movement. The robot  moves in a fish way, so it is very difficult to distinguish it or at  least isolate it on the background of a real marine fauna. It can swim  above and dive to depth. Such shark can rich an enemy ship unnoticed.  She can spy, repair ships, and arrange sabotage.  The robot-spider. From the beginning it is worth mentioning that the  spider model was printed using the 3D printer. The engine is integrated  with the servo motors of the paws, three in each: the resulting system  provides simple control of flexible, plastic movements with convenient  coordination from the control panel. He was shown in one of the series  of MythBusters.  Underwater robot-snake. The mechanical snake is designed to perform  maintenance and repair of various mechanisms on the seabed, mainly on  oil platforms. It is capable of replacing costly autonomous underwater  vehicles, easily slipping into places where cumbersome robots can not  reach.
