This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and is used in the FIRST LEGO League 2025-2026 UNEARTHED competition. It completes Mission 13: Statue Rebuild, collects the other team’s minecart, delivers a flag next to the minecart extraction area, and transports all artifacts from the Right Base to the Left Base.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 12: Salvage Operation and part of Mission 15: Site Marking in the FIRST LEGO League 2025-2026 UNEARTHED competition. It raises the ship, pulls the sand lever to clear the sand, and places a flag in its designated position next to the Salvage Operation mission model.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 14: Forum and Mission 15: Site Marking in the FIRST LEGO League 2025-2026 UNEARTHED competition. It delivers all the artifacts to the Forum and places the flag in its designated position nearby.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 10: Tip the Scales in the FIRST LEGO League 2025-2026 UNEARTHED competition. It releases the large scale, latches onto the Scale Pan, and transports it safely back to base.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 11: Angler Artifacts in the FIRST LEGO League 2025-2026 UNEARTHED competition. It aligns the robot with the Angler Artifacts mission model and rotates the gear mechanism to raise both the artifacts and the flagpole.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 02: Map Reveal and Mission 03: Mineshaft Explorer in the FIRST LEGO League 2025-2026 UNEARTHED competition. It pushes two of the topsoil sections aside and lifts the third to extract it. The robot then moves backward and raises the rail, allowing the minecart to travel onto the other team’s field.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and is used to complete Mission 05: Who Lived Here?, Mission 06: Forge, and Mission 07: Heavy Lifting in the FIRST LEGO League 2025-2026 UNEARTHED competition. The attachment positions the robot accurately in front of the mission models and interacts with each mechanism in sequence. In one run, it presses the Forge lever to release the stones, activates the Who Lived Here? model, and pushes a stone into the Right base. In a separate run, it pushes or captures the Millstone and transports it to the Right base.
This attachment is designed for the Smaller Pancake - SPIKE Prime Box Robot and completes Mission 01: Surface Brushing in the FIRST LEGO League 2025-2026 UNEARTHED competition. It pushes and pulls the Soil Deposit to release and extract the Brush.
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.
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.
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.
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.
