Lin admits that Devil is not good enough, particularly in its physical stability and algorithm, but he still wants to present the immature product. He sees Devil as "a toddler who is learning to walk".

Even while filming, Devil stopped working or broke down several times and, every time, Lin would patiently repair it.

Lin's passion for robotics began in his first year at the High School Attached to Shanghai Normal University, when a teacher, surnamed Zhou, discovered his talent for working with computers. Zhou provided full support to advance Lin's skills and took him to various computer science competitions.

"When I found that I could make things move in any way I wanted, the feeling was really amazing, even shocking," Lin recalls.

Coding and robotics have changed his life, Lin adds, and he wants to bring the benefits of technology to a wider audience.

During senior middle school, he developed a smart home system to help physically challenged people to remotely control their home appliances. "It was the first time that I understood how my products could help others," Lin says with pride.

Since September 2019, Lin has uploaded 19 videos to Bilibili, which act as witness to his growth from a senior middle school student to a university freshman.

At the end of the Devil video, the versatile young man played Robotics; Notes on piano and trumpet, the soundtrack of a Japanese "science adventure series" of video games with the same name, which has robotics and augmented reality as its main themes.

For Lin, Devil is just a beginning, and he believes that he and his products will make a difference in the future.
