Building Instructions -

• LEGO MINDSTORMS

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.

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

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. 

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 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. 

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

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

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

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

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.

Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.

When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.

Build with LEGO Mindstorms EV3 parts. 

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 

A simple active attachment that could be added to the Box Robot Chassis.

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.
