Our First Mechanical Fish Our teammates have invented our own first mechanical fish. The fish is operated by the use of a remote control. It can swim back and forth as well as can float and dive. It can also turn itself around while other mechanical fish cannot. Though it still looks a bit stiffly, this can be improved through the use of computer programming later. The invention is really a breakthrough for us as those made by the Peking University and Tsinghua University cannot even dive. We would like express our gratitude to our school and Mr Kan for offering us useful advice and resources to invent the fish.
