12-year-old American has come up with a scavenger robot

The 12-year-old American girl created a unique water purification system that caught the attention of many large manufacturing companies in the United States.

According to the young inventor Anna Du, she spends a lot of time near the water, and during one of her visits to Boston Harbor, she drew attention to the countless number of scattered plastic bottles and other debris on the shore. The girl’s strength was not enough to completely clear the coast, and she seriously thought about how to solve the problem of pollution.

The result is a scavenger robot with an infrared sensor that can identify plastic objects.

The smallest plastic particles about 5 mm in size cannot be assembled by standard nets. Meanwhile, according to preliminary estimates, only in the Arctic Ocean the number of such particles is about 12,000 per 1 kg of ice.

Infrared sensors can easily detect plastic, because it has the ability to absorb infrared radiation. As a result, the work of the robot on the principle of exposure is similar to the work of the remote control that controls objects at a distance.

Anna Du was invited to the Young Scientist Lab; the girl will have the opportunity to improve the characteristics of her invention under the guidance of experienced specialists.
