Scientists have created a fish robot that can swim alone 36 hours and the power supply it comes from an artificial circulatory system. As the design is use coral fish-lion. The constructor Robert Shepard told from the University in Cornel notes that the speed of swimming, which is currently about 0.01 km/h, can be improved. At the moment the fish robot that can swim upstream at a speed above 1.5 lengths of the body of the minute, which is about 15 centimeters per minute. At the time the scientist determines the speed of swimming as very slow, but there were what to improve.
“Fish” is supplied from the liquid electrolyte, which flows between the two electrodes. When the fluid is moving, it powered pumps and placed in the queue of the robotic fish, dorsal and breast blades. The flow of the liquid also increase and the pressure in certain areas. “Mechanism is as inflation of the bubble, which leads to a change of the form and the hardness of the parts of the robot”, explains Shepard. The Liquid inflates one side of the tail of the robot and causes compression of the other, which leads to the characteristic for the fish queues movement.
