Building Instructions

Maze Runners are one of the very popular robotics competitions. But there are a lot of limits that the robots must comply with. Like the size of the robot. 

This here are building instructions for a very small maze runner robot, build with LEGO Mindstorms EV3. It uses two tires that are technic and not Mindstorms simply because none of the Mindstorms tires fit the size limit. 

The robot has an Ultrasonic sensor and a Gyro sensor at the top. 

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. 

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

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.

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.

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.   

"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. 

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.

Building instructions for a LEGO Mindstorms EV3 Motorcycle, but this time with helper wheels. The helper wheels solve the problem of making turns with the robot. If the robot loses balance it will fall. The goal of the helper wheels is to make it easier for the robot to turn. Small modification, but really make a difference. 

Winter might be far away or it might just be coming - depending of course on where you are in the world. But you can always spend a few hours having fun with a LEGO Mindstorms Snowmobile. A really challenging construction that requires good preparation, concentration and a lot of efforts to complete. Same is going to the mountain in the winter. But the reward at the end is worth it. 

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.

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.

"Do. Or do not. There is no try!"

You probably remember this famous line spoken by Yoda in the film "Star Wars Episode V: The Empire Strikes Back". We've created FREE 3D and animated building instructions of LEGO's Star Wars "The Child (75318)" build-and-display model. Except the obvious cuteness overload, we did our best to create the 3D steps in the easiest way possible, so you DO manage to build "Baby Yoda" successfully, because trying is not an option. Fun you shall have, in 3D you shall build! Ready to go?

This is the "most valuable player" robot. It has many possible modifications, including ones that allow it to bend and reshape. Attachments and redesigns will soon be linked here, so you get an idea of the few ways MVP earns its title.

Let's play some basketball

Tricky might be the smallest Mindstorms 51515 Robot Inventor robot, but it's definitely one of the greatest. If you build Tricky with this particular Basketball attachment and grab the Mindstorms/Duplo ball, which is included in the set, you'll unlock a whole new level in playing basketball at home. Yes, yes, we know that you'll also need a basketball hoop, so you'll find a link for it below.

You can find the LEGO set, with which this was built, by following this link.

You can find other attachments for Tricky, by following the links below:

1. Kick the ball attachment
2. Writing attachment
3. Ball grabbing attachment
4. Turning attachment

You can find constructions created to play with Tricky, by following the links below:

1. Bowling Pins
2. Football Goal
3. Chain Reaction
4. Basketball hoop

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.

So I was looking around the house and I thought- "This will be fun for the kids. Let's build a coffee machine". Little did I know how fun it will be. Built from LEGO SPIKE Core set 45678 + LEGO SPIKE Expansion Set 45680 this Coffee Machine has a lit that could be opened/closed and is with the right size for the hands of an 6-10 years old child. What my daughters did with it is to have some coffee with the other toys. It is fun for them to construct and was really interesting that you can open and close it. As an engineer I had the chance to tell them a few words about the valve on the machine and why it is needed. Best ~2 hours of play for this week.

Play time for a week: ~2 hours in total
