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.
Building instructions for a LEGO robot that shoots 40 mm ping pong balls. The shooting mechanism is powered by two EV3 Large motors, while the whole mechanism is rotated by a medium motor. The robot can store up to 6 ping pong balls and has a Ultrasonic Sensor to detect targets.
There is a lot of physics and math involved when learning with LEGO Mindstorms EV3 robots. It is generally "difficult" to include them directly during classes because students are coming for "something funnier" and at the same time, they could be of different ages. But Inertia is a pretty common topic that is quite easy to introduce to students, especially with a robot.
The robot moves and stops. What will happen with the cargo when the robot stops? Naturally, the cargo will continue moving and this is dangerous. For how long, what would be the energy? All these are things that could be discussed with this robot.
The robot is not completely finished because you have to finish it and decide on the wheels to be used.
Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".
It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it.
Build with LEGO Mindstorms EV3 set.

User this flywheels construction for experiments in physics. Start rotating the wheel and they would accumulate energy. You can try to calculate this energy and to measure how fast it would be consumed.
The construction is built with LEGO Mindstorms EV3
