• EV3-G

VEX IQ version of an Easy Bot. It's simple and appropriate for classes of students. 

This is the first type of an active geared attachment. "Active" means that is is power by a motor. "Geared" means that it use gears. "Reusable" means that you can easily extend the attachment with additional parts - eg - you can reuse it. It shows a basic principle of how power is transferred between different axles that have different orientation in space- like when one of the axles is horizontal and the other is vertical. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad and others. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.

Pallo, from ancient Greek, means to throw or to hurl, which is a part of the modern name "catapult".

Pallo is a robot made of two parts. The first part of the robot is the catapult! It has no electronic parts and uses two rubber bands to shoot a projectile to the second part. The second part is the target. It has a color sensor, which through a piston with different colored sections, determines how accurately the target has been hit! Good luck with the shooting!

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.

Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.

The attachment is constructed from LEGO Mindstorms EV3 sets.

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.

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.

The Chain Monster is one of the coolest Box Robots that we've built. But what is a robot without attachments that can accomplish missions? These here are 3D building instructions demonstrating how the frame for the robot could be built. We've discussed frames in the Box Robots courses for EV3. Take a look at this one. See if it can inspire you to build robots and attachments in certain way to achieve consistent and reliable robot behavior.

With this LEGO Education SPIKE Prime attachment we accomplish the basketball mission from the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to put the ball into the basket and to have the basket up at the end of the round. This is a complex attachment. It uses gear wheels and warm gears to transfer the power from the motor to the top of the attachment. At the top of the attachment there is a wheel with a rope. The rope is build with LEGO Education SPIKE Prime parts. If you have the chance, use a different LEGO rope, but if you don't that this one will be ok.

With this attachment we complete the Elevator and Steel construction for the FIRST LEGO League 2019-2020 competition. The attachment is placed on the Whakatae - LEGO Education SPIKE Prime Competition Box robot

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.

VEX IQ robot base for Cube Collector 2

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.
