Take a close look. The chassis is from
last season. In fact, this is just a teaser. There are no such thing as a "catapult" on that robot. The ball is simply sitting on the chassis. Our team has tried few different ideas to launch it or use a catapult. It takes a lot of force to get that ball to launch upwards. I would be very surprised if I see a team succeed at launching the ball more than 20".
