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.

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.

Cápa means shark in Hungarian.

The robot resembles a live hammershark. It uses a medium motor to move its tail, which is used for the shark to turn. It moves forward with a large motor and two tyres. Its jaws open and close with a second large motor. The two touch sensors at the front are purely for aesthetics but you can use them if you like. Finally the head has an ultrasonic sensor which detects if something is a potential "prey". This resembles the real hammer sharks' ability to sense with their "hammer".

This construction demonstrates one way of using а rack with a gear wheel. It allows to turn circular motion in to a liniar one.

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.

This is a vehicle that is used to help you to learn programming, to experiment with addons, attachments and constructions. It has a frame. Which is nice. A frame is always nice. 

It has two wheels at the back, but this is needed only if you have them.

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?

Background

A space telescope is astonishing, but it can’t beat the accessibility and simplicity of a college or science museum observatory – that is, if you know how and where to point it.

Mission

Rotate the observatory to a precise direction.

This is a garbage container—and it’s fun! Like most real garbage containers, it has only three wheels because one is missing. You’ll also notice that one of the wheels is slightly different and tilted to the side—just like the real thing.

The container is great for play and for storing small items inside.

Suitable for children aged 6–10. Build the garbage container and leave it out for a week—children will naturally engage with it and are likely to spend at least an hour playing with it over the course of the week.

Big Wheelster, as the name suggests, is a robot with a big wheel! The large wheel is built using SPIKE Prime baseplates. The robot also features an interesting steering mechanism. At the front, we’ve added a touch sensor to detect obstacles—and hopefully avoid them!

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.  

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.

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.

Whitiki comes from Maori and means Belt.

The robot uses a medium motor to run the belt and a color sensor to identify the color of the ball coming in. There are 56 chain pieces in the 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.

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.
