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 first thing every student wants to build is a LEGO Mindstorms EV3 robot with treads. Well, we have one. Take a look. It's really funny.

Can you make it move? Send us a video or picture in the comment section below.   

This is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.

Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring. 

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.

Building instructions for a LEGO Mindstorms Robot that cleans the landing site when landing on a different planet. Built from an EV3 set it is a perfect simple tank robot with continuous tracks for lifting and moving things. Basically cleaning.   

Building instructions for a LEGO Mindstorms EV3 robot base. The attachment of the motors is quite interesting. We follow the angles of LEGO technic to attach them. This construction has some difficulties turning to the left and to the right. But if you have to take on an obstacle that high this is one of the options. 

You can use all kinds of wheels on this robot - EV3, NXT or others. It doesn't actually matter.

This here is a base for a robot that has the brick Upside Down. Have you seen Stranger Things? We would admit that this robot does not look exactly like a 'Demogorgon', but this here is the challenge. Can you use this base and make the robot look like a Demogorgon. Add a picture to the comments section below the material.

Do you have other ideas for Demogorgon? Build them with LEGO and add a picture below this material or send it to [email protected]. We would feature it at FLLCasts.com.

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.   

Let's build a robot with treads. These building instructions are for a Guard Tank Robot. The good thing about tanks is that they could tackle a lot of obstacles on their way. At least this is what people are saying. Try it. Could you move over LEGO parts with this tank if they are one brick tall, or two bricks tall? What would be the largest obstacle that you could find, over which this tank could still move? Share a video or picture below in the comments section.

We would admit that this tank lacks a gun or an arm, but it is up to you to build one.

Building instructions for a LEGO Mindstorms EV3 robot that could be completed in about 3 minutes. Could you do it? Try it. 

We use this robot when we need something very fast for a demonstration or a small competition. Just attach the motors and you are ready. It is fast.

Again a LEGO animal. This time it looks like an ant. It's interesting that this robot has no wheels and moves in a way very different from the rest of the "wheel robots". 

There is much to be learned about mechanics from the way animals move. Ants are a good example. In the real world, an ant could carry a load of 20x its mass. It would be interesting to see how much load could this robot carry? Try it. 

Building instructions for a LEGO Mindstorms animal that looks like a Penguin, and walks like a penguin and if you program it, it will even talk like a penguin. Can you program it to talk like a penguin?

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 

Building instructions for a LEGO Mindstorms EV3 robot that we call Space Explorer. The motors are attached in a very interesting way to the brick. Both the brick and the motors are vertical and there are not many robots like this. With its ultrasonic sensor, this robot allows you to follow, find or avoid objects. Just like an explorer. And since it is a robot why not put it in space and call it "Space Explorer".

There is one part that is not from the EV3 sets, but you can actually skip it. You don't need it. Try to find which one.

This LEGO Mindstorms robot is strange. Can you guess what is strange about it?... The motors are placed in a reverse direction. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you make the robot move forward with a Tank Block in the EV3-G software it will just rotate. To make the robot move forward, you will have to make one of the motors rotate forward and the other one - rotate backwards.

The goal of this robot is to teach students that motors could be placed in many different ways. It is not always the case that the two motors face the same direction. Also, it is quite fun. 

"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. 

"How do you build a forklift using only gear wheels and levers without a rake"... Ok, we would admit that is a difficult question. It even sounds difficult. So let's start with something easy. A LEGO Mindstorms EV3 robot. It lifts objects in the air. It uses two gear wheels that work together and then move in different directions and are placed perpendicular to each other... This sentence kind of got difficult again... Let me try again.

Follow the building instructions with these 70+ steps and you will have a very nice robot and you will learn a simple trick of how to use gears and change the directions in which they rotate.
