Building Instructions

A LEGO Mindstorms construction for taking loops. Uses the same principle as a carabiner.

Building instructions for the LEGO Mindstorms attachment using Rubber Bands

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

Building instructions for a LEGO Mindstorms EV3 Active attachment for changing gear orientations

Building instructions for this LEGO Mindstorms EV3 robot used in the World Robotics Olympiad Junior competition

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. 

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.

This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.  

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

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

Attachment frames are used on Base Robot Chassis to make it easier to add and remove attachments very fast. This frame is for the Box Robot 1. It is a single module build with LEGO Mindstorms EV3 parts and it could handle attachment on all sides. 

No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.

Build with LEGO Mindstorms EV3 

Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.

A robot attachment placed on the right side of the LEGO Mindstorms Box robot chassis. It uses two gear wheel to move a level. The level could collect things.

The central axle of the robot is most of the time the most important. The robot moves forward and does things with this axle. It is important to learn to you could extend such axles, and change the level and position of the extensions.

This is a LEGO Mindstorms EV3/NXT robot attachment.
