Building Instructions

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.

The robot uses two Large Mindstorms EV3 Motors to open and close its shell. On the top of the shell are used four hoses, that can be reshaped to form different shell styles. It also uses two black bent beams for eyebrows, that can be moved to change the expression of the clam. A Castor Ball is used to represent its pearl.

"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. 

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.

VEX IQ Steering Rover Car with remote control.

An awesome ski-jet robot, steering with a medium motor and powered by a single large motor. It also has a pair of inclined treads, making it especially well-suited for the harsh winter terrain.

*There is a mistake in this robot you will have to find. How would you make it work?

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. 

Value was inspired by the spy vehicle robot. This little robot was built to measure the volume of the room he's in.

Dwell is a car built with a LEGO MINDSTORMS EV3 set. It uses the medium motor for powering the back wheel and one more medium motor for rotating the front wheels and thus turning. Of course, there is a differential at the back.  

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.

This a the Dinore3x, the predecessor of the mighty Triceratops. This is one of the classic EV3 robots provided by LEGO. 

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.

A hand-driven Ferris wheel for a cascade scene—something like the famous Ferris wheel moment from the movie Le Boulet.

Or imagine a story where... a chicken fights two hunters and sets off an explosion so powerful that the shockwave launches the chicken to the top of the highest cabin, while the hunters are blown so far away they don't even appear in the thumbnail! Or... well, yeah, I remember a story...

Just open your mind to the strangest and most unusual story you can imagine.

Estimated weekly playtime with a good story: ~2–3 hours.

"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?

Alice is a lovely little bird, with some amazing mechanisms on her feet. It uses two large motors and one medium one as a head, which drives both its wings.

Building instructions for a LEGO Mindstorms EV3 robot where the motors are at the back of the horizontally placed brick and they are placed vertically. This construction is difficult to turn with but at the same time is quite high and could be used as a base for different trucks or animals.
