Watch the 4M Green Science – Aqua Robot swim along when sunlight shines on its solar cells. Watch this Aqua Robot swim along when sunlight shines on its solar cells. Aqua Robot can be powered by battery when there is no sunlight.
A robot fish that floats and paddles on the water’s surface with the power of the sun or a regular battery. Includes robot parts, solar panel and instructions. Requires one AAA battery (not included).
How does a solar panel work?
A solar panel “works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity,” according to Live Science. That’s a technical way of saying that the panel’s photovoltaic cells convert the energy in sunlight to electricity (specifically, direct current (DC))
