Developing an infrared ROV to identify microplastics

Credit: 3M Young Scientist Lab

At the age of 12, Anna Du realized that microplastics were a problem for our oceans.  She decided to build a remote-operated vehicle (ROV) that uses a high-resolution infrared camera and 3 types of light to spot plastic on the ocean floor. The vehicle is not meant to pick up the plastic, but rather to locate it. Du effectively used the design process to address the problem of plastic in the ocean and hopes to one day become an engineer.

Check out her video where she explains how the ROV works.
