Long runs are an excellent test of consistency. In this ten-attempt tutorial from the FIRST LEGO League 2025–2026 UNEARTHED competition, we put the Smaller Pancake box robot and the M14 and M15 transport attachment through one of the longest runs on the field.
Sometimes the most effective solutions are also the most straightforward. In Mission 14: Forum from the FIRST LEGO League UNEARTHED season, the Smaller Pancake box robot uses a lightweight pinless attachment to deliver the collected artifacts safely into the scoring area.
Sometimes the best final run is the one that does exactly one job. In this FLL 2025 UNEARTHED competition tutorial, the Smaller Pancake box robot uses the Site Marking attachment to carry the flag straight from base to its destination in under ten seconds.
No Equipment Constraint: A mission model cannot earn points if it is touching equipment at the end of the match.
This is the beautiful version of the robot. :) It is more likely for having fun, than use it for competition. It have beautiful front that is not very useful for a competition, due to larger attachments, but it is a little bit more stable than the "uglier" and smaller version. :)
This robot is very low, relatively compact and very hard to control. To move as desired it must carry heavy attachment between its front tires. It also needs often clearing of its rear balls and the beads where they are positioned. Ones that is done the robot becomes pretty accurate. If you change the front tires with tires that have higher grip than the ones in the Spike set it becomes precious. Spike Prime Tires don't have grip but looks good. :)
It is ideal to learn how to control robots in real world applications where nature plays bad jokes on the engineers.
The two color sensors look up so it can see the attachment control parts, so it decides what part of the program to run. It have only one attachment motor with only 1 attachment element - 28 Teeth and 4 holes Gear.

This attachment have a guider mechanism that align the robot to the attachment. The attachment woks with SUV Box Robot.

This is a carabiner attachment for taking loops. It is built with LEGO Education SPIKE Prime parts and it demonstrates how to successfully take loops. The goal of the attachment is to lock the loop after it catches it. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions
This is an pinless robot attachment designed for taking loops. It's built with LEGO Education SPIKE Prime parts and it demonstrates how to collect a loop while moving with the robot. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. There are other attachment that are designed for taking a loop and locking it so that it does not fall, but they are more complex. Search for 'Carabiner' at FLLCasts.com
Attachment for grabbing loops build from LEGO MINDSTORMS Robot Inventor 51515 set. We use this robot attachment to accomplish missions with loops at FIRST LEGO League. Well, we use the principle, that is what's important. Check out the attachment and the course to understand the principle of grabbing loops.
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.
The MiniBox box robot features a unique design with three perpendicularly rotating gearwheels, which simplifies the attachment design process. This setup allows teams to easily create and connect attachments on multiple sides, making it quick to adjust the robot for various tasks.
Its structure includes walls with a maximum attachable surface area, offering flexibility in attachment placement. This extensive surface allows for secure connections, so teams can experiment with different attachment configurations.
The MiniBox’s compact size is best suited for smaller, lightweight attachments. When working with larger attachments, its balance and stability can be affected, limiting its effectiveness in tasks that require more substantial setups.
As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it.
(we are releasing the video without explanations and will add the explanations later)
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M09. STRENGTH EXERCISE. I could think for a couple of missions in previous years that require lifting a heavy object. Let's see how this mission could be accomplished.
