• LEGO MINDSTORMS EV3

This is a real competition robot with three light sensors and a gyro.

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.

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. 

Umjaho - from the language of the Zulu tribe. It means "competition"

This LEGO Mindstorms EV3 robot has three sensors - touch, color and ultrasonic. When the touch sensor is pressed the robot starts moving. The color sensor is used for following lines and the ultrasonic sensor is used to detect any robots in front of the robot. 

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.

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.

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. 

Uylam is a robot that simulates a stormy environment for its ship. It is made using two piston-like mechanisms powered by a Large motor and offset by 90 degrees to create shaking similar to that of big waves. The ship itself is made out of a medium motor on a turntable and a gyro sensor attached to them. The purpose of this is to explore what is the best position of a ship compared to the waves, so that it sustains the least amount of shaking.

Building instructions for the robot used in WRO 2014. It is a small robot with two light sensors and could be used for collecting elements. 

The robot is built from LEGO Mindstorms EV3 parts. 

This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.  

Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here. 

Together the controller and the car look like this:

The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.

Mintonette comes from the first iteration of Volleyball with the same name.

The robot uses two EV3 Touch sensors to control the turret left and right. It uses the EV3 Color sensor to trigger the shooting mechanism, which consists of an EV3 Large motor which pulls a lever to shoot a ball.
