Building instructions for a simple LEGO EV3 robot built using two large motors and a color sensor. The robot is compact which makes it perfect for following a line. Note that the motors are upside down, which will make the robot go backward when we program it to go forward.
Building instructions for a LEGO Truck. The robot is presented as an Ammo Truck but it can be used for transporting various other objects, too. The construction has a rear drive with each of the rear wheels driven by a Large Lego Motor. The front wheels steer using a Medium Lego Motor. The Brick is placed at the front of the construction which gives the opportunity to easily attach different sensors, based on the task.
Building instructions for the Formula 1 Racing Car, built with LEGO Mindstorms EV3. It can turn with the help of a small motor and is driven by two large ones.
An example program for using this robot could be found at: https://www.fllcasts.com/programs/692hkz-comet-program
Piscis from Latin means fish.
Piscis is a LEGO fish robot which uses a very interesting mechanism for turning. It's tail uses a medium motor to turn left or right. On its end there are two wheels. When the robot turns its tail, those wheels navigate the movement of the robot and it turns. This results in a cool turning mechanism which resembles how fish move.
Piscis also uses a large motor to move forward and backward. The touch sensor at the front helps it sense danger and return quickly back to the reef.
Watch out for the tooth wheels, they bite!
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.
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
Francesco 2 is inspired by the robot Francesco.
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. Differently, from Francesco, Francesco 2 has space where a locking mechanism is meant to be built for the differential.
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.
Sebastian is a six-legged creature, which technically makes it not-a-crab. Anyway, it still walks sideways and is amazing to build and watch.
You can find the program for Sebastian here.
The central axle of the robot is most of the time the most important. The robot moves forward and does things with this axle. It is important to learn to you could extend such axles, and change the level and position of the extensions.
This is a LEGO Mindstorms EV3/NXT robot attachment.
This drag car is a two-motor version of the Drag car robot. With more motors comes greater power!
A fearsome and dangerous robot. It will find a place to hide and patiently wait in ambush.
NB! This robot requres bluetooth connectivity, as its USB port is blocked in the construction.
This is a version of the Midas - a LEGO Mindstorms EV3 Clam robot. The main difference between the two robots is that the motors are flipped.
The robot uses two Large Mindstorms EV3 Motors to open and close its shell. There are four hoses on the top of the shell which 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.
Instructions for building the quick attachments for this LEGO robot
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.
These are modules for you to create your own robot that sorts plastic trash as used in C2. The two modules are not connected anywhere, they are just placed together so you have an easier time imagining the robot.
A phone holder that rings an alarm when the phone is picked up. It is a plate, lying on a rubber wheel, that changes its height, based on the weight of the object placed on top. The color sensor detects these changes and rings the alarm. With some fine tuning, this robot can even act as a weighing machine.
This is a LEGO Mindstorms Boxing robot. The inspiration story goes like this "One day we though - Let's play SUMO at this robotics demonstration, but let's make it more interesting. Let's play sumo with Humanoid Robots". We decided to build a boxing robot. The goal of the robot is to press the touch sensor on the other robot and it could be very fun. Perfect robot for demonstration. It is controlled by a joystick using the Bluetooth connection.
Here are the joystick and the programs for the joystick and the robots.
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.
Instructions for building a LEGO truck. We use a medium motor for steering and a large motor for driving one of the rear wheels.
