The building guide for the FIRST Technical Challenge Push Bot build with the Tetrix set

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

This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees. 

It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things. 

The attachment could be built from LEGO Mindstorms EV3 and NXT parts. 

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. 

Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.

The frame contains parts from LEGO Mindstorms EV3.

This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.

For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.

Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.

Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.

Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.

Building instructions for the second module of the Ugbroid robot - the Base.

Building instructions for module 3 of the Ugbroid - the drive mechanism.

Building instructions for building rear wheels - module 4 version 2 of the Ugbroid.

Building instructions for Module 1 of the Modular EV3 LEGO Mindstorms vehicle - the Trunk.

The goal of this robot is to teach students how to build modular robots. This first part is just one of the modules. 

Instructions for building module 4 version 1 of the Ugbroid - rear wheels.

Again a LEGO animal. This time it looks like an ant. It's interesting that this robot has no wheels and moves in a way very different from the rest of the "wheel robots". 

There is much to be learned about mechanics from the way animals move. Ants are a good example. In the real world, an ant could carry a load of 20x its mass. It would be interesting to see how much load could this robot carry? Try it. 

This is a simple LEGO EV3 Mindstorms Robot that can collect items within itself.

Building instructions for the Easy Bot built with LEGO Mindstorms EV3 parts. This LEGO robot is suitable for classes with students in robotics and is one of the first robots that we build. It takes about 10-20 minutes to be constructed by first-time participants.

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.
