This amazing work is an autonomous roboic fish which can keep off obsticles and have sensor to swim in the tank easily. It’s an improvement from the electronic fish which had to use remote control, this robot fish has “artificial intelligence based” to contain itself. This design is a landmark to develop better sea floor explorations and petroleum detections. The fish can swim in the water for five hours and it fastest speed can up to 20 inches per second. Professor Huosheng Hu are reseaching more further to make a robot fish which can eat and feed itself like a real fish. I think the most effective part is how the fish sway in the tank with the way that water flows!
