Building Instructions

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

The MiniBox box robot features a unique design with three perpendicularly rotating gearwheels, which simplifies the attachment design process. This setup allows teams to easily create and connect attachments on multiple sides, making it quick to adjust the robot for various tasks.

Its structure includes walls with a maximum attachable surface area, offering flexibility in attachment placement. This extensive surface allows for secure connections, so teams can experiment with different attachment configurations.

The MiniBox’s compact size is best suited for smaller, lightweight attachments. When working with larger attachments, its balance and stability can be affected, limiting its effectiveness in tasks that require more substantial setups.

This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the rotary sensor, embedded in every motor, to detect when the player has pulled the lever.

These are instructions on how to build the:

Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".

It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it. 

Build with LEGO Mindstorms EV3 set. 

When placing the rubber bands check out the tutorials

Placing the white rubber band is shown at https://www.fllcasts.com/tutorials/105-rubber-band-attachment-with-a-flywheel-solving-fll-2014-search-engine-part-2 at around 05:40.

The NXT Competition robot was the first competition robot we designed. For most of the part in 2011-2012-2013 it was working really great. Than EV3 was released

This is Cooley, and, it, is, coooooool. It got all the stuff the cool kids have - two motors at the top, two at the bottom, two wheels on the side and it is slim. Build a few attachments for it and take it on a ride during FIRST LEGO League competition

This is an attachment that could be easily detached. It's built with LEGO Education SPIKE Prime parts and it demonstrates how to build an attachment that could be easily detached. In competitions you need this easy detachment as on FIRST LEGO League/World Robotics Olympiad and other robotics competition you need to save time. The principle is the same. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the course in which this attachment is used for more information and tutorials on how to use it.

Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions. Compared with previous versions of this robot, this one has a Gyro Sensor. 

This robot was made to count coins. The door slides, making the gyro sensor rotate, and by doing that, allowing the robot to measure the size of the coin that enters the safe. By changing the points where the gyro's beam connects, the sensor's thresholds change.

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.

Building instructions for LEGO EV3 catching robot. It uses a medium motor to drive system of gears, which is used for catching objects. It, also, has an ultrasonic and colour sensors for detecting the objects. 

Calix comes from Latin, meaning cup.

Calix is a robot designed to carry small objects—like a cup—while autonomously following a black line. When most people think about robotics, they imagine machines helping with household chores. Calix is a simple example of that vision brought to life. You can place a cup on it in the kitchen, and it will deliver the cup to the end of the black line!

The robot is powered by two SPIKE Prime medium motors for movement, and it uses a color sensor to follow the line precisely. At the front, a large motor connected to a gear system lifts and lowers the cup, allowing for easy pickup and delivery.

Calix is an elegant demonstration of how even simple robots can be designed to perform useful tasks—making robotics more approachable and practical for everyday life.

This robot is a veriation of the Spark Bot without steering wheel.

The goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams. 

The construction could use EV3 or NXT wheels, so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.

Cápa means shark in Hungarian.

The robot resembles a live hammershark. It uses a medium motor to move its tail, which is used for the shark to turn. It moves forward with a large motor and two tyres. Its jaws open and close with a second large motor. The two touch sensors at the front are purely for aesthetics but you can use them if you like. Finally the head has an ultrasonic sensor which detects if something is a potential "prey". This resembles the real hammer sharks' ability to sense with their "hammer".

This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor. 

Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.

The demo programs for this motorcycle are here.

This is a version of the Gazon robot that has a single color sensor and is useful for cases where you still have not purchased a second color sensor, but need to start working on the FLL competition season missions

The goal of this robot attachment is to demonstrate a principle and example for dropping an object. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.

The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.

In the LEGO Mindstorms Robot Inventor set there is only one color sensor. The original Gazon is build from LEGO Education SPIKE Prime where there are two light sensors. The idea behind this robot is to be able to build it from Robot Inventor and to use it during FIRST LEGO League competitions
