Last year, he met a little girl named Emma at a community event. Emma was born without a right arm and her artificial arm was old. What’s worse, it cost a lot to buy a new one, and her family couldn’t afford it. Jake felt sorry for Emma. He decided to help her. He worked on a new design for an artificial arm. He built it out of cheap materials like plastic blocks and fishing line. After many tests, the arm worked well—it was able to move with Emma’s brain signals! Jake didn’t stop there. He wanted to help more children like Emma. So he posted his design online for free. Soon, many people from different countries knew about it. Some volunteers even helped make the artificial arms and sent them to children in need. At age 16, Jake won an award for his great work. He said, “I just wanted to give them a helping hand.
