Building Instructions

Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3

These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments. 

This attachment is accomplishing three missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot

This is an attachment for the Kriket box robot. It demonstrates how to build attachments that glide over the robot, are pinless and could be quickly and easily replaced and changed with another attachment. This attachment also lifts. Quite cool. Quite cool.

These are 3D Building Instructions for the Theater Scene Change mission model for the FIRST LEGO League 2023-2024 MASTERPIECE competition.

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

 

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.

These are instructions on how to build the:

• Bat
• Inspection drone
• Support axles
• Coach Pins
• Precision tokens
• Dridge Entrace
• Bridge Top

for the FIRST LEGO League 2019-2020 City Shaper Challenge.

You can find more building instructions and tips and tricks about the competition on this page.

These are the official robot rules for the FIRST LEGO League Hydrodynamics 2017-2018 robot missions. 

Background

Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.

Mission

Get the lander to one of its targets intact, or at least get it to base.

Scores

• Move the lander to be intact, touching the mat, and completely in its target circle: 22 OR
• Move the lander to be intact, touching the mat, and completely in the northeast planet area: 20 OR
• Move both parts of the lander completely into the base: 16
• Possible scores: 0, 16, 20, 22

Scoring Requirements

• The result must be visible at the end of the match.
• The lander is “intact” if its parts are connected by at least two of its four tan location axles.

Robot building instructions for a World robotics Olympiad with a large container used for collecting ping-pong balls

Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.

SIngle robot attachment, many points. 

These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.

Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.

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!

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.

It kind of looks like an Inuit. But it surely walks like one. Most of the time Inuit walk with special boots that allows them to walk on deep snow without getting stuck. This robot walks in the same way. It has large feet and it moves one after the other. 

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:

Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions.
