• LEGO MINDSTORMS EV3

Chronos means time in Greek.

What's the time? Time to build a cool robot! This robot is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes it simple to build, while also being effective in showing how a clock works.

An example program moving the seconds and minutes hands of the clock can be found here.

An example program designed to teach children to read the clock can be found here.

Building instructions for a LEGO Mindstorms EV3 Multi-axles mechanism

Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.

This robot is made to serve the best tea in the whole continent! It is based on the Easy Bot from EV3. As its predecessor it is based on LEGO Mindstorms EV3. It uses two large motors to move around. The best part of the robot is the cup holder, that has a cool cup that shows the KISS principle.

This robot is a spin-off of the Useless machine built from LEGO Mindstorms EV3. This robots mission is to be the last to press the button it holds.

This is a very funny robotics hand with 3 fingers that you could put on your hand to "Rule the World". It's funny to control it with the touch sensors.

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:

This is a robot, designed to easily lift a cup, while still holding it upright. The robot uses one motor attached to the brick to lift the cup to any angle you want. The cup we have added is purely cosmetic, but with a few adjustments, you can make it lift real cups. Be careful around liquids though!

This is another LEGO Mindstorms grabber, but this time it has 4 fingers! They are moved simultaneously by a medium motor. The grabber was taken from Cron - LEGO Mindstorms EV3 Crane.

Do you have a friend for a sleepover? This might be the perfect robot for you! It is a football gate, guarded by Fint, the goalkeeper robot. You can control him, by using the remote controller, that consists of two Touch Sensors. Take turns making penalty shots and have a blast with this awesome robot!

What we recommend:

• Using a big LEGO wheel from your set as a football ball.
• If you throw the wheel too fast for the robot to catch, increase the distance between the place you shoot the ball from and the robot.

Motivated by the five-minute robot, this robot has its own rails!

Building instructions for the most simple grabber using just one Large EV3 LEGO motor. It has one static lever and one active lever.

This module is made as a grabber that uses a cool mechanism to catch things vertically. It is powered by a medium motor. The grabber is used in Earl Bot - Grabbing and Clearing LEGO Mindstorms Robot without wheels.

This frame holds the motor and ev3 brick used in the catapult. The frame is placed on top of the rotating base and thus could be easily rotated. The brick could be both NXT and EV3

Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult. 

This robot construction itself was used in the FIRST LEGO League Senior Solutions competition

Building instructions for a LEGO Mindstorms Catapult Motor and Touch Sensor that are used for triggers for firing objects

This is a module containing two sets of three legs to make the ideal hexapod insect! The two sets are each powered by a large EV3 motor which are connected in various ways to the three legs to move them like a real bug! You can combine this module with others to build a bug robot.

This is a cool scissor mechanism that looks like the sting of a scorpion. It is powered by a medium motor and at the top there is a touch sensor, to detect if something has been stung! The sting is used in Scorpion - LEGO EV3 Robot.

This is a module that is made to look like a polar bear head, but really it could be used for many animals. It uses a medium motor to bite and an ultrasonic sensor for eyes. We have labeled it a polar bear head, because it is used in Polar Bear - LEGO Mindstorms EV3 Robot that looks like a polar bear.
