Building instructions for this LEGO Mindstorms EV3 robot used in the World Robotics Olympiad Junior competition
Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.
Build from LEGO Mindstorms EV3 parts.
This is one of the robots used in World Robotics Olympiad. It uses chains to move ping pong balls out of a container.
LEGO Mindstorms Robot Base for a high placed attachment for containing ping pong balls. It is interesting how the balance is achieved with such an attachment. It was only one of the version in a series of LEGO Mindstorms Robots for World Robotics Olympiad.
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.
Building instructions for the Pinless Rubber Band Attachment:
For World Robotics Olympiad Ball Collection competitions we prepared an interesting Robot Base Chassis that could be extended with a container. The container contains the ping-pong ball. A mechanism collects them. This LEGO Mindstorms EV3 building instructions are for the chassis of the robot and were one of the versions from a series of robots.

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.
One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.
These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.
You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.
The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.
Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.
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
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
This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.
This is a simple LEGO Gear System with a ration of 1:5. When the large wheel rotates 1 time the small wheel will rotate 5 times.
Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.
