3D Instructions on how to add a diode to the Raspberry Pi and indicate when the Raspberry Pi is turned on. 

In this 3D scheme, you can see how the motor driver is connected to the Raspberry Pi and to the motor. Follow the steps in the instructions one by one and you will have successfully connected the motor to the Raspberry PI

3D scheme on how to connect the L298N Motor Driver to the Batteries. Follow the step-by-step instructions. Be careful about the PCB terminal connectors.

3D scheme with instructions on how to connect the L298N driver to the batteries and to the motor. Just that. Connecting to the Raspberry Pi is at a later stage of the course. 

A 3D scheme on how to connect the front steering motor to the Raspberry PI. This includes the Motor Driver and the batteries. The rear motor is also on this scene. 

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.

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. 

The goal of these building instructions is to build a simple LEGO Mindstorms EV3 robot without wheels. You should then think of yourself how exactly to add the wheel. Which wheels would you use on the front? How are you going to build the third wheel? Here are for example a few recommendations on building the third wheel - 1, 2, 3, 4 

Later on you can expland this construction with a grabber as demosntrated here. 

A LEGO door with a touch sensor that knows when it's open. It has a stopper and even makes the familiar noise of a creaky door. You can use it by its own or put it in a model of a house.

A nice little robot that can tell if there is anything on top of it. It only uses one touch sensor. The idea of the robot is to be used in classes with students to explore different interesting security options. This robot in particular could detect when the object placed on it gets "stollen". Have you ever watched Indiana Jones? :)

Do you have a friend for a sleepover? This might be the perfect robot for you! It is a football gate, guarded by Fint, the goalkeeper robot. You can control him, by using the remote controller, that consists of two Touch Sensors. Take turns making penalty shots and have a blast with this awesome robot!

What we recommend:

• Using a big LEGO wheel from your set as a football ball.
• If you throw the wheel too fast for the robot to catch, increase the distance between the place you shoot the ball from and the robot.

Cápa means shark in Hungarian.

The robot resembles a live hammershark. It uses a medium motor to move its tail, which is used for the shark to turn. It moves forward with a large motor and two tyres. Its jaws open and close with a second large motor. The two touch sensors at the front are purely for aesthetics but you can use them if you like. Finally the head has an ultrasonic sensor which detects if something is a potential "prey". This resembles the real hammer sharks' ability to sense with their "hammer".

This robot is a spin-off of the Useless machine built from LEGO Mindstorms EV3. This robots mission is to be the last to press the button it holds.
