Building Instructions

Building instructions for a LEGO EV3 Robo-tank. The construction is incredibly simple, with an upright Brick, which makes it perfectly suitable for lessons with students.

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.

Building a third wheel for a LEGO Mindstorms EV3 Robot is always an interesting and challenging task. These building instructions are for a third back wheel. You can even notice that there is no wheel involved. It is just LEGO parts but it is one of the most stable ways to build a third wheel. There is some friction, of course, but not that much.

Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.

The left attachments work synchronously, and the right attachments are also synchronized couple.

These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us. 

Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.

Building instructions for a simple chain tread machine. The robot is actually a simplified version of the Freedom Folk Race tank. All of the ultrasonic sensors are stripped away and the robot can be used for multiple different tasks. The construction is appealing to students and simple enough to be included in a class.

This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees. 

It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

Building instructions for LEGO EV3 robot with color wheel that can be rotated through the medium motor. The color wheel is at the front of the robot while there is a color sensor at the back. The color sensor could read the color from another robot. The robot can be used in classes with students to play the telephone game.

An example of a program for controlling the robot could be found at https://www.fllcasts.com/programs/kmeat9-ev3-g-myblock-for-rotating-the-color-wheel-randomly

Building instructions for an EV3 LEGO Mindstorms Dump Truck. The back of the truck can be tilted through controlling the medium EV3 motor so that the load can be dumped at a desired location. Also, the robot has a color sensor to determine the type of load it is carrying. 

Iknathir from armenian means aircraft carrier.

The robot is made to resemble an aircraft carrier. It shoots paper airplanes using two fast spinning wheels. The wheels are connected to a gear up mechanisms which are connected to two Large motors. The motors themselves are connected to a medium motor, which allows them to move towards and outwards the plane so when they reach it, they are spinning at full speed. The plane is placed on a runway which leads it to launch successfully. On the side of the robot, there is a lever with a gyro sensor, which is used to trigger the launching mechanism. 

Antares is the brightest star in the Scorpius constellation.

The robot's main purpose is to show two different grabbing mechanisms - one vertical and one horizontal. The vertical pincers use a medium motor and the horizontal pincers use a large motor. Additionally the robot has a sting mechanism which uses another large motor. For a head it uses an EV3 ultrasonic sensor. With the sensor, the robot can sense when the prey is close enough for a suprise attack.

Build from LEGO EV3 Core and Expansion set this robot looks like a scorpion. The Scorpion strikes, when it sees a pray with the ultrasonic sensor and you can use the touch sensor and the rotation sensor to control the spike movement. It has a scissor mechanism at the back using a system of gears and levers. 

The goal of this robot attachment is to demonstrate a principle and example for lifting heavy objects vertically. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.

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.

Mintonet (engl. Mintonette) comes from the name of the first iteration of volleyball.

The robot can move only forward and backward, without turning, with the help of a large EV3 motor. Another large motor is used to shoot. The robot uses an EV3 ultrasonic sensor to detect its partner and throw a ball at it.

A LEGO Mindstorms EV3 Chassis with wheels at the front. Built with the EV3 set you can use this robot chassis as a base for extending with attachments. 

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.

Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.

Geldautomaat, from German, means ATM.

This is the last robot from the 3.0 course book in the LEGO Mindstorms Curriculum. It uses a Touch Sensor to sense if there is a card inside. When touched, a Medium Motor starts spinning and pulls the card inside its chamber, where a Color Sensor reads the data from the card.

NOTE: There is a step, where you have to place the "credit card" inside. It may seem unnecessary and pointless, but otherwise, you will not have proper support for the next steps and the construction will crumble.

Building instructions for a Wall-E like robot. The robot is on treads, driven by two Large EV3 motors. Has two static hands and an ultrasonic sensor on top.
