These are video tutorials for designing and constructing durable, reliable and stable LEGO Mindstorms constructions. Both the EV3 and the NXT robotics sets are used. We prefer to show the construction along with the process of how we engineer it, re-engineer and how we come to the final solution.
You could also find robotics tutorials about constructing robot attachments. During each FIRST LEGO League, World Robotics Olypmiad and other competitions based on LEGO, the attachments more than important.
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.
Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult.
This robot construction itself was used in the FIRST LEGO League Senior Solutions competition
The goal of these building instructions is to build a LEGO Mindstorms EV3 robot without wheels. You should then decide on your own how exactly to add the wheel. Which wheels would you use at the front? How are you going to build the third wheel? Here are some recommendations on building the third wheel - 1,2,3,4
The goal of these building instructions is to build a simple LEGO Mindstorms EV3 robot without wheels. You should then think of yourself how exactly to add the wheel. Which wheels would you use on the front? How are you going to build the third wheel? Here are for example a few recommendations on building the third wheel - 1, 2, 3, 4
Later on you can expland this construction with a grabber as demosntrated here.
These are construction plates used as Mission Model for preparing for FIRST LEGO League competition off season. They are build with LEGO Mindstorms Robot Inventor set and following the idea of the same places with LEGO Education SPIKE Prime construction plates and LEGO Mindstorms EV3 construction plates
This construction uses a differential. Both wheels could turn with different speed and this makes a construction much more stable when turning.
This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.
Advanced LEGO MINDSTORMS EV3 Construction. It has two rear motors and it could rotate the whole from part. It has 4 wheels and is kind of like unique in the Mindstorms world.
Building instructions are not very easy and you need LEGO Education Core and Extension Sets - 45544 and 45560.
Apart from being advanced, it is also quite fun to try to build.
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.
It sparks. It's sparkling. Well, 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.
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.
Building a third wheel for a LEGO Mindstorms EV3 Robot is always an interesting and challenging task. These building instructions are for a third back wheel. You can even notice that there is no wheel involved. It is just LEGO parts but it is one of the most stable ways to build a third wheel. There is some friction, of course, but not that much.
There are so many ways to attach the motor to a Mindstorms Brick. We haven't counted them, but we sure like to experiment with them. This is one way. Not the perfect, not very stable sometimes, but you could also learn from prototypes and "mistakes". And the LEGO brick is on the same level as the motors. Follow the building constructions and have the motors attached to the sides of this Mindstorms Base construction.
Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.
Build from LEGO Mindstorms EV3 parts.
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.
