Most of the units of the robotic fish were printed out by 3D printing technology. As the tail and fins parts were produced with soft material, the robotic fish can mimic the movement of a real fish. /VCG Photo

With the help of the buoyancy control units, Sofi could dive to 15 meters deep for up to 40 minutes each time. /VCG Photo
