• LEGO MINDSTORMS

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

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.

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:

• Bridge Road

for the FIRST LEGO League 2019-2020 City Shaper Challenge.

You can find more building instructions and tips and tricks about the competition on this page.

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 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 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.

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.

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

The kinesthetic and memory game works with a program you can download from here. In these instructions you will see the 7 modules from which it is built:

• Touch sensor module;

• Ultrasonic module;

• Gyro module;

• Color module;

• Lever module;

• Medium motor module;

• Base module.

This robot is meant to be very modular and to enable its owner to upgrade it and modify it.

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

It moves and it collects. It collects objects.

These are building instructions for a LEGO Mindstorms robot that could collect objects. It is not actually catching them and that's why we call it "Simple Catch Bot". The general case is to program it to move on the floor and collect some of the Mindstorms wheels and tires coming with the 45544, 45560 or 31313 LEGO sets.   

Instructions for building a steering chassis from LEGO EV3 Mindstorms. It uses EV3 Large motor to power the rear wheels and EV3 Medium motor for the steering mechanism. Find building instructions for the remote control here.

This is one of the robots used in World Robotics Olympiad. It uses chains to move ping pong balls out of a container.

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.

"Bot. Spy Bot."

Many of us are fascinated by the idea of spies. Movies for "spies" are also very popular and if you haven't watched them check out the 007 movies. These here are building instructions for a LEGO Mindstorms robot with two touch sensors and one ultrasonic. It could be used as a spy - sneaking closer to you and detecting if you move or if you touch it. The whole idea for this robot came from NXT when there were sound sensors. Currently, there are no sound sensors in the EV3 set, but the robot could again be quite fun to program. 

Building instructions for the robot used in WRO 2014. It is a small robot with two light sensors and could be used for collecting elements. 

The robot is built from LEGO Mindstorms EV3 parts.
