This attachment for the Nautiq robot is designed for missions M13 Coral Reef, M12 Raise the Coral, and M09 Release the Shark from the FIRST LEGO League 2024-2025 SUBMERGED competition. It features a passive mechanical trigger that releases a lever powered by a rubber band. A passive curtain mechanism is included for collecting parts from the field. The attachment is optimized for quick and reliable mission execution without additional motors.

This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot. The attachment solves the light show mission using rubber bands! It works well, but it does depend on how new your model is. On newer models it can work with only 2 red rubber bands or even with 2 yellow and 2 red. Find the best combination for your field.

The trigger for the light show mechanism also releases Anna the Museum Curator and the masterpiece on the pedestal.

A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.

This attachment is designed to detach, once it completes its purpose. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.

This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot.It collects Izzy using a rubber band mechanism, solves the M13 Craft Creator with a hook and M12 Virtual Reality Artist using a gear that goes into the mission model.

These are building instructions for an attachment accomplishing the FIRST LEGO League 2017-2018 Slingshot mission. The based of the robot is LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro

Accomplish three FIRST LEGO League missions at once. This is an interesting Large multi-purpose FLL attachment for a box robot that could be used to accomplish a number of missions with a single exit of the field base. 

Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".

It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it. 

Build with LEGO Mindstorms EV3 set.

Building instructions for a LEGO Mindstorms EV3 Ambulance Robot Attachment for the FIRST LEGO League 2013 Nature's Fury robotics competition.    The attachment grabs the ambulance car and slightly lifts it. The rubber bands help with triggering the attachment at the right time

Building instructions for the Pinless Rubber Band Attachment:

Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.

Build from LEGO Mindstorms EV3 parts.

Pallo, from Ancient Greek, means "to throw" or "to hurl"—a root of the modern word "catapult".

Pallo is a robot made of two parts. The first part is the catapult! It contains no electronic components and uses two rubber bands to launch a projectile toward the second part. The second part is the target. It features a color sensor which, using a piston with differently colored sections, detects how accurately the target has been hit. Good luck with the shooting!

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.

If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.
