Following the Spy Bot, we have this new Spy Vehicle. Yes, yes it is using an ultrasonic sensor.
The building instructions are for a robot base that looks like a car but is not exactly a car and has a strange shape. Just like spy vehicles - a car, but not only a car and not just a car.
"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.
Building instructions for a LEGO EV3 steering car. We use two large motors, so that the rear wheels will be driven independently by a separate motor. For your convinience, you can use the EV3-G MyBlock for moving the Boomer.
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.
"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.
Building instructions for a steering car. The front wheels steer through a Medium LEGO EV3 motor while the rear wheels are both driven by a single Large LEGO EV3 motor.
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.
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 is a disk image containing a Raspbian OS. The image is modified and set up specifically for the Perfect course. It contains all the needed files, libraries and additional tools that we would use in the course. The file is quite large so be prepared to wait some time while downloading.

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.
There is a lot of physics and math involved when learning with LEGO Mindstorms EV3 robots. It is generally "difficult" to include them directly during classes because students are coming for "something funnier" and at the same time, they could be of different ages. But Inertia is a pretty common topic that is quite easy to introduce to students, especially with a robot.
The robot moves and stops. What will happen with the cargo when the robot stops? Naturally, the cargo will continue moving and this is dangerous. For how long, what would be the energy? All these are things that could be discussed with this robot.
The robot is not completely finished because you have to finish it and decide on the wheels to be used.
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.
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.
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.
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 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.
