These are all the robot building instructions. By visiting each building instruction you could see the Tutorials and Courses and Lessons in which it is used.
This is a simple robot, variation of the Earl bot using treads. You can use the attachment to kick balls sideways. The robot is useful in STEM classes where students have to construct robots quickly.
Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.
Mintonet (engl. Mintonette) comes from the name of the first iteration of volleyball.
The robot can move only forward and backward, without turning, with the help of a large EV3 motor. Another large motor is used to shoot. The robot uses an EV3 ultrasonic sensor to detect its partner and throw a ball at it.
