The new, soft, folding “Pokemon” like robot called, "Rotary Actuated Dodecahedron" (RAD) is cutting across the obstacles faced by humans when they use hard tools underwater and hurt the soft and delicate ocean creatures for the purpose of studying them.

The device has been tested, first at Connecticut's Mystic Aquarium and then in the open ocean near Monterey, California. It successfully captured squid and jellyfish unharmed after being mounted to an unscrewed underwater vehicle and controlled remotely via joystick.
