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 building instructions are for a robot that kind of looks like the Spy Bot but it has treads instead of wheels. Like a Tank. Tank Spy Bot. Treads are always funny and you could use the robot chassis base to extend with additional attachments and tools. 

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 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.

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 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 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.

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.

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.

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. 

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

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".

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.

In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?

Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.

A LEGO Mindstorms construction for taking loops. Uses the same principle as a carabiner.

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

Rollbar is a handy device, which only purpose is to measure lengths. Its main purpose is to measure curved lines.

It's designed for right-handed people, but with some small adjustments, it could fit any palm.

This construction demonstrates one way of using а rack with a gear wheel. It allows to turn circular motion in to a liniar one.
