The CubeHunter uses the ultrasonic sensor to detect a ball or cube. Next, the robot catches it and reads the colour of the object using the EV3 colour sensor. The building instructions are suitable for classes with students and if you are working alone at home.
A nice little robot that can tell if there is anything on top of it. It only uses one touch sensor. The idea of the robot is to be used in classes with students to explore different interesting security options. This robot in particular could detect when the object placed on it gets "stollen". Have you ever watched Indiana Jones? :)
Barco from spanish means boat.
The robot is made to look like a sail ship. The sails are made out of technic panels, attached in various ways to create the best look. Otherwise the robot uses two motors with tyres to move. At the back of the robot there is a Gyro sensor, which helps it maneuver.
This is the simplest possible line following robot. It has just one sensor in the front between the two driving wheels and uses beams as pivots instead of a third wheel. Try it out. Follow the building instructions and start following lines in a number of minutes.
WatchTower is a pretty self-explanatory robot. It detects intruders by sensing the vibrations they make while walking or digging beneath it. For this purpose, it uses a Gyro sensor, which could be incredibly sensitive under the right circumstances. The Ultrasonic sensor that sits on top of a medium motor starts locating the intruders when the Gyro sensor detects them.
Probably the largest multi-purpose FLL attachment at FLLCasts. These attached is doing a number of missions at once. 4 of them. You attach it to the robot and start the program. The robot moves and accomplishes a number of missions using only this attachment. At it also has a lot of parts. It is quite large and you can not build it from a single set. But that's ok because you are preparing for a competition, right?
We love bears. These are great creatures. Do you know that the Polar Bear is the largest bear there is.
This robot was first constructed years ago for some of the first classes in LEGO Mindstorms Robotics that we held. It is quite challenging, but nevertheless very rewarding when completed and when you manage to program it to walk. Check it out.
This is a Camel-like robot. We demonstrate an interesting use of gears to make the Camel walk. Fun and entertaining way to learn how to transform motion.
A LEGO door with a touch sensor that knows when it's open. It has a stopper and even makes the familiar noise of a creaky door. You can use it by its own or put it in a model of a house.
The third version of the EV3 Easy Bot. This is a simple and easy to follow robot, that aims at showing the use of tyres on robots. The robot has a gear up ratio and no tyres, so it is quite fast and entertaining.
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.
Susan comes from Sue, which is the name of the largest fully preserved specimen of T-Rexes.
Mark comes from Marc Bolan, who is the lead singer/gutarist of the band T-Rex.
The robot is made to resemble a T-Rex (Susan) chasing a car (Mark).
The T-Rex uses a Large motor to go forward and backward. The other Large motor is used for the car, which resembles a very simple 4-wheel vechicle. Susan's task is to spot Mark using the current power option of the motor rotation sensor. As T-Rexes can not notice you if you are moving very slow, Mark is trying his best to move really slow so that he doesn't get spotted!
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
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.
LEGO Mindstorms EV3 Robot designed for a Folk Race competition. This robot has three Ultrasonic Sensors. Follow the building instructions and at the end, you would have a very basic robot with tank treads that you could directly use.
Maze Runners are one of the very popular robotics competitions. But there are a lot of limits that the robots must comply with. Like the size of the robot.
This here are building instructions for a very small maze runner robot, build with LEGO Mindstorms EV3. It uses two tires that are technic and not Mindstorms simply because none of the Mindstorms tires fit the size limit.
The robot has an Ultrasonic sensor and a Gyro sensor at the top.
Gen comes from Gendema, a bulgarian late 80s rock band, popular with its song about pedalos.
The robot uses two EV3 Large motors to move, but instead of wheels it uses four-legged paddles, attached to the motors. This makes it look like a pedalo. Additionally it slides on the ground much like a real pedalo on the water.
Because of the strange mechanism of movement, the robot has a gyro sensor to help it keep a straight line.
The building instructions are for a robot that kind of looks like the Spy Bot but it has treads instead of wheels. Like a Tank. Tank Spy Bot. Treads are always funny and you could use the robot chassis base to extend with additional attachments and tools.
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.
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.
