Chinese engineers have created a soft-bodied fish robot that can swim like a manta ray.
Fish-the robot is not equipped with a traditional solid motors, or motors, it moves with the help of “artificial muscles” made of modern high-molecular materials.
This fish is able to swim like a Stingray and by following the commands to move forward or to change direction. The robot’s weight is 90 grams, and its body length is about 9.3 cm or 18.5 inches, if you count the tail.
The developer of the robot, the engineer Tiefeng Li from Zhejiang University in Hangzhou used in the wiring diagram of the robot of the surrounding water as a “main electrode”. As it turned out, this use for robots of low power does not defeat the surrounding current. Under the influence of electric current “artificial muscle” contracts or expands, thus she sets in motion the fins of the fish, explained Typing Lee.
With mounted electronic devices and a rechargeable lithium battery with a capacity of 450 milliampere robotic fish can swim for three hours at a speed of 6 centimeters per second. If you remove all electronic devices and to replace the lithium battery external power supply, its speed is up to 14 centimeters per second.
According to experts, the fish-robot can be widely used in work on measurement of temperature, salinity and pollution of sea water.
