The octosub

Phineas

Age 10Helston, UK

Back to all ideas

The octosub is my 2nd submarine to design and it is special because it has 3 arms that can be controlled from the inside.

Little Inventors team says

The Octosub looks brilliant! With all those controllable arms they could do great things under the sea like collect up all the plastic or search for treasure in shipwrecks. Well done Phineas.
