The team has constructed two fish robots. The larger prototype is about one and half metres in length, weighing about 10kg and it can dive to a depth of 1.8m. The smaller robot is about 60cm long and weighs a mere 1.5kg. It is developed for investigation on 2D motion control and motion-planning in a small place, and it can only swim at water surface.

"To my knowledge, the world's smallest fish robot is one about 127mm in length. It was designed by MIT for specific military purpose and could go to a depth of 1.5m," said Dr Ren.

The team hopes to make their robot fish even smaller and more realistic. Mr Fan said, "We intend to equip it with more sensors like GPS and a video camera to improve autonomous 3-D movement. We also intend to test out our fish with more challenging tasks such as object detection."
