Separate the robot construction on body - body and attachments. Attachments should be small, light and most importantly for winning the competitions they should be pinless. In this category we group tutorials, courses and materials for different attachments that have proved to be useful.
This attachment is accomplishing three missions and partly two more missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot
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.
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 is a Kriket box robot attachment used for pushing a lever and precisely dropping energy units. It is used for FIRST LEGO League 2022-2023 SUPER POWERED mission call M03 Energy storage and M11 Hydroelectric Dam. This is a multi-purpose attachment that can do more than one thing at a time.
This is an attachment for the Chain Monster robot and it accomplished three missions that are all push and deliver. It technically is not used for the M09 dinosaur toy, but this is because the toy is on the robot while the attachment is below the robot
This attachment is part of a second versions 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 versions to make sure there are enough examples of how to use the Kriket box robots
This is an attachment for accomplishing missions from FIRST LEGO League 2022-2023 SUPER POWERED competition. We use this attachment additionally to another one that you can see the the lessons for this attachment. The goal is to execute the actions of Push and Collect, and this is the perfect passive attachment for this.
Instructions for building the quick attachments for this LEGO robot
The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.
Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.
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.
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.

This is a self aligning passive attachment for rendezvous and meeting between the tube module and the habitation hub.
The program for this attachment is Self Aligning Module Attacher for M06 - Space Station Modules.
There is another program at Self Aligning Module Attacher for M06 - Space Station Modules - another program.
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
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.
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.
This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 5th mission of the FLL Cargo Connect competition.
This attachment is accomplishing three missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot
