Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.
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
Building instructions for a simple LEGO EV3 robot built using two large motors and a color sensor. The robot is compact which makes it perfect for following a line. Note that the motors are upside down, which will make the robot go backward when we program it to go forward.
Building instructions for the Formula 1 Racing Car, built with LEGO Mindstorms EV3. It can turn with the help of a small motor and is driven by two large ones.
An example program for using this robot could be found at: https://www.fllcasts.com/programs/692hkz-comet-program
Building instructions for a LEGO Truck. The robot is presented as an Ammo Truck but it can be used for transporting various other objects, too. The construction has a rear drive with each of the rear wheels driven by a Large Lego Motor. The front wheels steer using a Medium Lego Motor. The Brick is placed at the front of the construction which gives the opportunity to easily attach different sensors, based on the task.
Piscis from Latin means fish.
Piscis is a LEGO fish robot which uses a very interesting mechanism for turning. It's tail uses a medium motor to turn left or right. On its end there are two wheels. When the robot turns its tail, those wheels navigate the movement of the robot and it turns. This results in a cool turning mechanism which resembles how fish move.
Piscis also uses a large motor to move forward and backward. The touch sensor at the front helps it sense danger and return quickly back to the reef.
Watch out for the tooth wheels, they bite!
Third version and a third way to build a third wheel for a LEGO Mindstorms EV3. The instructions are easy to follow and in the end you will be able to attach this wheel to your robot by yourselves.
Another building instruction for a third wheel suitable for a LEGO Mindstroms robot. This one is classical. Just a few parts but could be used on a lot of different robots. There is some friction when turning so this one is more suitable if you have to do more straight movements.
Antares is the brightest star in the Scorpius constellation.
The robot's main purpose is to show two different grabbing mechanisms - one vertical and one horizontal. The vertical pincers use a medium motor and the horizontal pincers use a large motor. Additionally the robot has a sting mechanism which uses another large motor. For a head it uses an EV3 ultrasonic sensor. With the sensor, the robot can sense when the prey is close enough for a suprise attack.
Building instructions for LEGO EV3 robot with color wheel that can be rotated through the medium motor. The color wheel is at the front of the robot while there is a color sensor at the back. The color sensor could read the color from another robot. The robot can be used in classes with students to play the telephone game.
An example of a program for controlling the robot could be found at https://www.fllcasts.com/programs/kmeat9-ev3-g-myblock-for-rotating-the-color-wheel-randomly
Francesco 2 is inspired by the robot Francesco.
Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels. Differently, from Francesco, Francesco 2 has space where a locking mechanism is meant to be built for the differential.
Geldautomaat, from German, means ATM.
This is the last robot from the 3.0 course book in the LEGO Mindstorms Curriculum. It uses a Touch Sensor to sense if there is a card inside. When touched, a Medium Motor starts spinning and pulls the card inside its chamber, where a Color Sensor reads the data from the card.
NOTE: There is a step, where you have to place the "credit card" inside. It may seem unnecessary and pointless, but otherwise, you will not have proper support for the next steps and the construction will crumble.
Classical third wheel for LEGO Mindstorms robots. This construction comes from the NXT world and the wheel is available in the NXT set.
Sebastian is a six-legged creature, which technically makes it not-a-crab. Anyway, it still walks sideways and is amazing to build and watch.
You can find the program for Sebastian here.
These are building instructions for a LEGO WeDo 2.0 Sweeper.
These are instructions on how to build the:
for the FIRST LEGO League 2019-2020 City Shaper Challenge.

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.
This drag car is a two-motor version of the Drag car robot. With more motors comes greater power!
A fearsome and dangerous robot. It will find a place to hide and patiently wait in ambush.
NB! This robot requres bluetooth connectivity, as its USB port is blocked in the construction.
This is a version of the Midas - a LEGO Mindstorms EV3 Clam robot. The main difference between the two robots is that the motors are flipped.
The robot uses two Large Mindstorms EV3 Motors to open and close its shell. There are four hoses on the top of the shell which can be reshaped to form different shell styles. It also uses two black bent beams for eyebrows that can be moved to change the expression of the clam. A Castor Ball is used to represent its pearl.
