Building Instructions

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. 

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.  

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.

This LEGO Mindstorms robot base is small, compact and packed in a very small volume. The goal of this constructions is to be used as a base and to show yet another way to experiment with adding motors to the brick.

Not all LEGO Mindstorms EV3 Robot should be aligned horizontally or vertically. It is quite possible to have the brick and the motors attached in such a way that the robot is at a certain angle. 

This is a very useful small construction that could be used as a base and extended with hands and heads or other interesting ....robot body parts.

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.

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. 

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. 

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.

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.

Classical third wheel for LEGO Mindstorms robots. This construction comes from the NXT world and the wheel is available in the NXT set. 

Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.

The frame contains parts from LEGO Mindstorms EV3.

Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.

A robot attachment placed on the right side of the LEGO Mindstorms Box robot chassis. It uses two gear wheel to move a level. The level could collect things.

When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.

Build with LEGO Mindstorms EV3 parts. 

Building instructions for a safe mechanism. The medium motor can be used for dialing in the key lock. The brick buttons can also be used for a pin code input.

One of the large motors unlocks the latch, the other one opens up the lid of the safe.

Instructions for building the quick attachments for this LEGO robot

One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.
