This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.

The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.

This attachment for the Nautiq robot is designed to accomplish M15 Research Vessel in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It includes one detachable part: the hook is removed after collecting the Research Vessel, and the remaining part is used to deliver it to its target location.

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 simple active pinless attachment for the Nautiq robot is designed specifically to accomplish mission M08 Artificial Habitat in the FIRST LEGO League 2024‑2025 SUBMERGED challenge. It offers a minimalist, efficient mechanism ideal for reliably completing the mission. No motors are required—setup is quick and intuitive. The compact design ensures stable performance and easy integration with the Nautiq robot.

This attachment for the Nautiq robot is designed to collect the Plankton and Seabed Sample, deliver the Unknown Creature, and accomplish M11 Sonar Discovery in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It enables multiple tasks to be completed efficiently in a single run.

In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. The purpose of this attachment is to demonstrate How NOT to build attachments. 

Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand. 

This is a simple pinless active attachment for the SUV Box Robot.

In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.

While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.

This attachment for the Nautiq robot is designed to collect the Krill, the Reef Segments, and the Water Sample, while accomplishing M05 and M10 in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It combines multiple functions to complete several missions efficiently in a single run.

Instructions for building the quick attachments for this LEGO robot

This is an attachment that accomplishes a mission. But they all do. This attachment is special as it is a Glide pinless attachment. It teachers the principles of building attachments that could be easily glided onto the robot and allow for quick changes of different attachments. It is designed for the

The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.

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.

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.

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. 

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

This attachment is part of a second version of attachments for accomplishing the M07, M08 and M15 where we have to push and collect in the FIRST LEGO League 2022-2023 competition. It is for the Kriket Box Robot and we are doing this second version to make sure there are enough examples of how to use the Kriket box robot.

The interesting part about this attachment is how it connects to the robot. The Kriket has two brown axles that are connected to the motors via a gear mechanism. The attachment is attached to these brown axles which transfer the motor movement to the attachment.

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. 

This attachment accomplishes the Into Orbit Extraction mission from the FIRST LEGO League Into Orbit 2017-2018 competitions. The based of the robot is the SUV Competition Box Robot from LEGO Mindstorms EV3.

The program for this attachment is at https://www.fllcasts.com/programs/2hpdg9-fll-2018-attachment-to-accomplish-the-into-orbit-extraction-05-robot-game-missions-program.

This is the attachment to accomplish Fll 2019 M06 mission with the Whakatae. You can see how to attach the attachment to the robot in this tutorial to do.
