This robot was designed for the VEX IQ Challenge 2019-2020. It could push four hubs simultaneously. It can carry one. And it call pull itself on the bar at the end of the run. We've used four omni wheels of which the two at the back are the driving wheels.

Demo program can be found at Program for Winner - VEX IQ Competition Robot for the 2018-2019 Challenge.

VEX IQ robot base for Cube Collector 2

Background

It is amazingly expensive to send heavy stuff like construction material into space, so scientists and engineers are instead learning how to print what they need in space, using available extraterrestrial elements.

Mission

The robot needs to get a regolith core sample and place it into the 3D printer, which will cause the 2 × 4 brick to pop out. The ejected 2 × 4 brick can then be delivered elsewhere for more points.

Scores

• The 2 × 4 brick ejected and completely in the northeast planet area: 22 OR
• The 2 × 4 brick ejected and not completely in the northeast planet area: 18
• Possible scores: 0, 18, 22

Scoring Requirements

• Results must be visible at the end of the match.
• Eject the 2 × 4 brick by placing a regolith core sample into the 3D printer. > Only allowed method. Must be obserserved by the referee.

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

This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example. 

The attachment was used during FIRST LEGO League 2014 Robotics competition.

This is an 8 bar lifting robot. Way should I build this instead of Roberto bot you ask? Because it is... well... it lift thing straight up, it lift 'em higher, it's more beautiful than Roberto and is more bad ass looking than 4 bar lifting mechanism. OOoohhh, and one more thing it may use the same program as Roberto Bot With Four Bars Lifting Mechanism.

The program si at programs/hb5rj8-pesho-bot-with-two-bars-lifting-mechanism-controls-with-modkit.

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.

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.  

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 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. 

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

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

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

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. 

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.
