In a junior high school, this stuff is cool. I programmed my tribot to do this program, which as we call it…the Sumo Bot competitioning program! I also built the robot myself. You can buy the EV3 mindstorm sets on some apps, preferably Ebay or Amazon. There is a home set and a educational set. The home set has more pieces but it’s still tricky to build without programs so you can/should also get the EV3 Mindstorms book. Or find the website online!😁 Hope you have a great day and sub/ like if you want!
