• LEGO MINDSTORMS EV3

Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3

Robot building instructions for a World robotics Olympiad with a large container used for collecting ping-pong balls

These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments. 

Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.

This is a very funny robotics hand with 3 fingers that you could put on your hand to "Rule the World". It's funny to control it with the touch sensors.

Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here. 

Together the controller and the car look like this:

Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions. 

A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.  

This is a robot, designed to easily lift a cup, while still holding it upright. The robot uses one motor attached to the brick to lift the cup to any angle you want. The cup we have added is purely cosmetic, but with a few adjustments, you can make it lift real cups. Be careful around liquids though!

We've separated the BigDaddy robot into a few smaller modules. This teaches modularity and gives you the option to reuse some of the modules and to look at specific modules.

Building instructions for the LEGO Mindstorms attachment using Rubber Bands

Mintonette comes from the first iteration of Volleyball with the same name.

The robot uses two EV3 Touch sensors to control the turret left and right. It uses the EV3 Color sensor to trigger the shooting mechanism, which consists of an EV3 Large motor which pulls a lever to shoot a ball.

Building instructions for the most simple grabber using just one Large EV3 LEGO motor. It has one static lever and one active lever.

The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.

This is a ping-ball containing attachment for a World Robotics Olympiad. The attachment is building with LEGO Mindstorms EV3 parts. It is tiltel so that it is easier for the balls to fall off at certain points, which was part of the missions at the 2015 cmpetition. 

This frame holds the motor and ev3 brick used in the catapult. The frame is placed on top of the rotating base and thus could be easily rotated. The brick could be both NXT and EV3

The Laboratory is a robot that tests your programming skills. You will have to measure the volume of a balloon, only by the values you receive from the sensors. 

It has a valve, that allows you to deflate your balloon at different rates.

How to place the balloon in the robot is explained in this tutorial.

A chassis built with LEGO Mindstorms EV3 parts designed for World Robotics Olympiad

Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult. 

This robot construction itself was used in the FIRST LEGO League Senior Solutions competition
