Building Instructions

This is one of the robots used in World Robotics Olympiad. It uses chains to move ping pong balls out of a container.

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

The kinesthetic and memory game works with a program you can download from here. In these instructions you will see the 7 modules from which it is built:

• Touch sensor module;

• Ultrasonic module;

• Gyro module;

• Color module;

• Lever module;

• Medium motor module;

• Base module.

This robot is meant to be very modular and to enable its owner to upgrade it and modify it.

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. 

VEX IQ Steering Rover Car with remote control.

Building instructions for the robot used in WRO 2014. It is a small robot with two light sensors and could be used for collecting elements. 

The robot is built from LEGO Mindstorms EV3 parts. 

This is a garbage container—and it’s fun! Like most real garbage containers, it has only three wheels because one is missing. You’ll also notice that one of the wheels is slightly different and tilted to the side—just like the real thing.

The container is great for play and for storing small items inside.

Suitable for children aged 6–10. Build the garbage container and leave it out for a week—children will naturally engage with it and are likely to spend at least an hour playing with it over the course of the week.

Building instructions for a LEGO Mindstorms EV3 Motorcycle, but this time with helper wheels. The helper wheels solve the problem of making turns with the robot. If the robot loses balance it will fall. The goal of the helper wheels is to make it easier for the robot to turn. Small modification, but really make a difference. 

Chronos means time in Greek.

What's the time? Time to build a cool robot! This robot is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes it simple to build, while also being effective in showing how a clock works.

An example program moving the seconds and minutes hands of the clock can be found here.

An example program designed to teach children to read the clock can be found here.

This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the rotation sensor in the medium motor to detect how much the players had turned its wheel.

This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.  

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the second attachment from the series.

Building instructions for a LEGO Mindstorms EV3 robot base. The attachment of the motors is quite interesting. We follow the angles of LEGO technic to attach them. This construction has some difficulties turning to the left and to the right. But if you have to take on an obstacle that high this is one of the options. 

You can use all kinds of wheels on this robot - EV3, NXT or others. It doesn't actually matter.

Winter might be far away or it might just be coming - depending of course on where you are in the world. But you can always spend a few hours having fun with a LEGO Mindstorms Snowmobile. A really challenging construction that requires good preparation, concentration and a lot of efforts to complete. Same is going to the mountain in the winter. But the reward at the end is worth it. 

This robot extends the Tetrix Box Robot chassis for FTC competitions with an additional arm. The arm could be used for lifting and placing objects and could be quite useful. 

There is a special rubber band at the end of the arm, because there are not enough parts in the Tetrix set and we had to use a rubber band. But the principle of the arm is interesting, useful and you should be familiar with it - the arm keeps the motors always in the right orientation.   

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.  

Not all LEGO Mindstorms EV3 Robot should be aligned horizontally or vertically. It is quite possible to have the brick and the motors attached in such a way that the robot is at a certain angle. 

This is a very useful small construction that could be used as a base and extended with hands and heads or other interesting ....robot body parts.
