We love bears. These are great creatures. Do you know that the Polar Bear is the largest bear there is.
This robot was first constructed years ago for some of the first classes in LEGO Mindstorms Robotics that we held. It is quite challenging, but nevertheless very rewarding when completed and when you manage to program it to walk. Check it out.
WatchTower is a pretty self-explanatory robot. It detects intruders by sensing the vibrations they make while walking or digging beneath it. For this purpose, it uses a Gyro sensor, which could be incredibly sensitive under the right circumstances. The Ultrasonic sensor that sits on top of a medium motor starts locating the intruders when the Gyro sensor detects them.
This is a Camel-like robot. We demonstrate an interesting use of gears to make the Camel walk. Fun and entertaining way to learn how to transform motion.
A LEGO door with a touch sensor that knows when it's open. It has a stopper and even makes the familiar noise of a creaky door. You can use it by its own or put it in a model of a house.
This robot is a simplified spinoff of the Box Robots (Box Robot 1 and Box Robot 2). It may be build with a single set, but it will require extra technic beams 7x5 with open centers.
The name of the robot - "Squmo" is derived from the ancient tradition of connecting two words to make on and hense - "Square sumo" because "Squmo".
Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.
Susan comes from Sue, which is the name of the largest fully preserved specimen of T-Rexes.
Mark comes from Marc Bolan, who is the lead singer/gutarist of the band T-Rex.
The robot is made to resemble a T-Rex (Susan) chasing a car (Mark).
The T-Rex uses a Large motor to go forward and backward. The other Large motor is used for the car, which resembles a very simple 4-wheel vechicle. Susan's task is to spot Mark using the current power option of the motor rotation sensor. As T-Rexes can not notice you if you are moving very slow, Mark is trying his best to move really slow so that he doesn't get spotted!
A phone holder that rings an alarm when the phone is picked up. It is a plate, lying on a rubber wheel, that changes its height, based on the weight of the object placed on top. The color sensor detects these changes and rings the alarm. With some fine tuning, this robot can even act as a weighing machine.
These are modules for you to create your own robot that sorts plastic trash as used in C2. The two modules are not connected anywhere, they are just placed together so you have an easier time imagining the robot.
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.
Yolanda comes from the novel "Yolanda, the Black Corsair's Daughter" by Emilio Salgari.
The robot resembles a sailship with two masts. The mast in the back is connected to a medium motor, which allows it to rotate with some limits. The mast also has a gyro sensor in the back. These are placed so that the gyro sensor detects which way "the wind is blowing" and moves the sails that way. The second mast is connected to the first one so that it moves accordingly. The robot also uses two large motors to move.
Accomplish three FIRST LEGO League missions at once. This is an interesting Large multi-purpose FLL attachment for a box robot that could be used to accomplish a number of missions with a single exit of the field base.
The third version of the EV3 Easy Bot. This is a simple and easy to follow robot, that aims at showing the use of tyres on robots. The robot has a gear up ratio and no tyres, so it is quite fast and entertaining.
Building instructions for this LEGO Mindstorms EV3 robot used in the World Robotics Olympiad Junior competition
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.
Space stations allow us to learn about and even practice living in space, but improved technology and new international partners require modules to be easily interchangeable.
The robot needs to remove and insert modules among the habitation hub’s portholes.

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.
These are building instruction for a working automatic catapult with a motor and a touch sensor.
LEGO Mindstorms EV3 Robot designed for a Folk Race competition. This robot has three Ultrasonic Sensors. Follow the building instructions and at the end, you would have a very basic robot with tank treads that you could directly use.
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This is the simplest module for constructing and programming. At the bottom, a channel is left for the cable to pass through.
