Anna Du was walking along the beach when she noticed plastics there. She reached down to pick them up, and quickly realized there were more tiny pieces than she could deal with. It seemed impossible to clean them all up.
Du, 12 years old at the time, tried to solve the problem like any good scientist—first, by doing a little research. That's how she learned that 8 million tonnes of plastics end up in the ocean every year.
Then she got to work, building something that could help solve the problem: a remote - operated vehicle, or ROV. Her ROV can move through water and find plastics on the ocean floor.
The actually cool part of Du's ROV is the detection（探测）system. She used a camera along with three different kinds of light to find the plastics. She also used visible（可见的）light to find unnatural colours that might make the plastics stand out.
“She has a very good engineering sense to break down a problem like this and then go after it,” says engineer Casey Machado. “It sounds simple, but it's a level of thinking that's really amazing.”
Du started attending public events and workshops at a university when she was five years old. She picked up the necessary engineering skills to build her ROV. She said actually getting her ROV to move through water well was not easy. She failed many times, but she never gave up trying and testing.
When asked about future plans, she mentions that she wants to address the effects of climate change. “I think there are a lot of problems that could be solved with new inventions,” says Du.
Du thanks her parents, who for years have taken her to student outreach activities, for supporting her interest in science, technology, engineering and Maths(STEM). She says she has been able to meet students and scientists there.
“I know I want to be an engineer because I like building things to help solve the world's problems,” says Du. “But I'm not sure what kind of engineer I want to be yet.”
