Sometimes robot builders are so overwhelmed with the process of constructing a robot that they forget two very important parts. The brick should be accessible and the cables should not get in the way. These are referred by us as Brick Accessibility and Cable Management.
This is a very interesting idea that is worth sharing with the rest of the teams and the ELM team has provided it to us. Check out how they drop a LEGO human at a specific place.
Building instructions for this LEGO Mindstorms EV3 attachment for the FIRST LEGO League Nature's Fury robotics competition
How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition.
We extract the Proportional Line Following algorithm into a new block with parameters. This allows us to experiment with the Threshold, Constant Speed and Relaxation Coefficient. You can now easily use the block in you other programs without having to implement it.
This is the first Active Pinless Attachment for the Box competition robot. The attachment is placed on the top of the robot and is controlled by one of the motors.
Building instructions for a LEGO Mindstorms Base Chassis with a reversible motor
Note: This robot contains wheels that are from the NXT set.
No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.
Build with LEGO Mindstorms EV3
Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.
We have to admit. This is quite an interesting missions. There is a Manhole cover and it must be turned upside down. Well, the robot must turn it. Again LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro is used as a base for the Robot.
One of the spacers that the Nightbeast team used in FLL 2018/19 Into Orbit Challange
score one or the other
If there is a team-designed Structure clearly bigger than a Blue Building Unit, built only from your white LEGO bricks
Note: Design and build your own Structure before you compete, then bring that to each Match. You don’t build it during the Match.
Note: Your mission 11 Structure needs to be built from Bag 10 elements only. It can include the red and gray elements. Not all of the Bag 10 elements need to be used.

The robot collects health units from around the field and moves them to target areas.
This Python program is for controlling Gazon, LEGO Education SPIKE Prime competition robot to accomplish FIRST LEGO League (FLL) 2020 RePLAY Challenge mission 02 - Step counter. Check out the lessons where this program is use for specific demonstrations and explanations on how the program works.
This robot attachment is placed at the front of a LEGO Education SPIKE Prime competition robot to facilitate and accomplish the FIRST LEGO League 2020 RePlay Step Counter mission. We can use the attachment or we can skip it.
This is a 10 out of 10 tutorial where we demonstrate a reproducible completion of a shared mission. The mission is shared as both teams must agree about how they are completing the mission. The tutorials shows the robot approaching the FIRST LEGO League mission model. You will see how the robot pushes on the lever every time for a 10 out of 10 completion.
This is a flip attachment. Arguably the flip missions are some of the most interesting on FLL competitions. The purpose of this attachment is to accomplish the FIRST LEGO League 2020 Cell Phone Mission. It contains two four gear wheels. It is an active attachment. It changes the direction with gear wheels. There is a lot one could learn from such an attachment. It is also build only from parts in the LEGO Mindstorms Robot Inventor Set.
This is a robot attachment build only from LEGO Mindstorms Robot Inventor parts and it is used to accomplish the Weight Machine mission at the FIRST LEGO League 2020 competition. It is not a completely accurate attachment but it shows a good idea on how to accomplish the mission.
In this video tutorial we discuss probably the most useful principle that we've found for FIRST LEGO League competitions and this is how to align to a line with two color sensors. We use the LEGO Mindstorms Robot Inventor for a quick demonstration of the principle. In the LEGO Mindstorms Robot Inventor Programming course we enter into more details of how exactly we program the sensors. The current tutorial demonstrates the use of such a program and makes clear why this could be very useful and is a must for any well prepared team and wants to achieve a good score on the competition.
A Scratch (World Blocks) program for LEGO Mindstorms Robot Inventor 51515 set. With this program we make the robot move forward and stop. In this way the inertia triggered attachment that is placed on the robot is activated and it falls down. Then we return back to base with this mission model that we've collected with the attachment
Activate the drop attachment with a python program
