I am a 15-year-old student living in Bangkok, Thailand. This is the go-kart I made for my MYP Personal Project in grades 9-10. The designing process took 4 months, and the material-gathering and build time took another 4 months. It now runs at a respectable 30 km/h, and is lots of fun to ride around. It was a big hit at the Personal Project fair, and is simple enough for me to allow the young children to drive around. The inner tubes in the rear wheels (which lacks a differential) tends to come out. I learned a lot over the course of this project about electronics, mechanics, engineering and fabrication techniques.
