Probably the largest multi-purpose FLL attachment at FLLCasts. These attached is doing a number of missions at once. 4 of them. You attach it to the robot and start the program. The robot moves and accomplishes a number of missions using only this attachment. At it also has a lot of parts. It is quite large and you can not build it from a single set. But that's ok because you are preparing for a competition, right?

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.

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.

Can you find out why the robot is called "Omusbot"?

The robot is made as a nice base for more advanced LEGO Sumo competition. It uses two motors, which are put on backwards for more traction. On the front, it has a color sensor, which detects the border line of the field. Over them, there is an ultrasonic sensor, that detects the enemy robot. Finally, on the back, the robot has a touch sensor to detect if it is being pushed.

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

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.

These are building instructions for an attachment accomplishing the FIRST LEGO League 2017-2018 Slingshot mission. The based of the robot is LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro

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.

Instructions for building a LEGO truck. We use a medium motor for steering and a large motor for driving one of the rear wheels.

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.

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

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. 

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. 

This attachment is meant to be built on the robot Francesco 2. When the red connector for the transmission connects the two axles for the rear gear wheels, the differential locks and the motor starts evenly transferring its power to both wheels.

When the red connector for the transmission is pushed to the side, the differential unlocks and once again transfers its power to the wheel with least resistance.

You can see empty beams hovering over this attachment. They are there so you can attach a lever construction over it, to help with the locking and unlocking of the differential. Similar leaver can be seen in the robot Catapult.

Building instructions for a LEGO Mindstorms EV3 robot where the motors are placed in an unusual manner. They are vertically placed on the sides. This robot construction base is very convenient for a quick and interesting robot on which you could build. 

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 is a LEGO Mindstorms Boxing robot. The inspiration story goes like this "One day we though - Let's play SUMO at this robotics demonstration, but let's make it more interesting. Let's play sumo with Humanoid Robots". We decided to build a boxing robot. The goal of the robot is to press the touch sensor on the other robot and it could be very fun. Perfect robot for demonstration. It is controlled by a joystick using the Bluetooth connection.

Here are the joystick and the programs for the joystick and the robots.

Building instructions for a safe mechanism. The medium motor can be used for dialing in the key lock. The brick buttons can also be used for a pin code input.

One of the large motors unlocks the latch, the other one opens up the lid of the safe.

These are building instruction for a working automatic catapult with a motor and a touch sensor.

Lintu means bird in finnish.

The robot is made to resemble a Kiwi bird, an endangered species of flightless birds, found only in New Zealand.

Lintu uses two large motors as legs. They are placed at an angle so that they resemble the strange posture of the kiwi bird.

The beak of the robot uses an interesting mechanism to open and close utilizing two technic steering links and a medium motor. For eyes, the robot uses an Ultrasonic sensor.
