The below video consists of four parts. The first part demonstrates the difference swimming robot octopus that only has flexible tentacles, and a robot, the tentacles of which are connected by elastic membrane. The speed of movement of the first robot is 100 millimeters per second, the second robot moves faster, its speed is equal to 180 millimeters per second. This difference is a very significant achievement because the amount spent by both robots energy is approximately the same.
The second part of the video demonstrates the capabilities of a robot octopus to move in shallow water and on land. It should be noted that the developers of the robot have been plausible enough to copy the way in which moves a live octopus that had a chance to go ashore. In the third part you can see like a robot-octopus, pulling a load, which is a yellow ball held by two tentacles. And in the fourth and final part of the video shows "military" testing robot octopus in the waters of the Aegean sea. Of course, to confuse the robot with a live octopus will not work even with a strong desire. However, the robot swims in water quite realistic and this view, apparently, adhere to marine fish that swim fearlessly close to the robot.
All that was shown in the video is a proof that the floating robotic octopus due to their unique propulsion system ideally suited for studies of the ocean, a condition survey of underwater engineering structures, to search for surviving members of the crews of naval surface ships and submarines, and to solve many other objectives of this plan.
In conclusion, it is worth noting that the research team from Greece has acquainted the public with his robot octopus and its possibilities in the framework of the International IEEE conference on intelligent systems and robots (IEEE International Conference on Intelligent Robots and Systems, IROS) 2014, held in Chicago.
