Even a simple lifting mechanism depends on a precise approach. In this 10 out of 10 analysis of Mission 13: Statue Rebuild from the FIRST LEGO League 2025–2026 UNEARTHED competition, we put the Smaller Pancake box robot and the Statue Rebuild attachment through ten consecutive attempts.
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.
When the attachment is simple, preparation makes all the difference. In this 10 out of 10 tutorial for the FIRST LEGO League 2025–2026 UNEARTHED competition, the Smaller Pancake box robot and the Forum attachment deliver the collected artifacts to Mission 14: Forum across ten consecutive attempts.
Short, direct, and almost identical every time. This 10 out of 10 tutorial from the FIRST LEGO League 2025-2026 UNEARTHED competition puts the Smaller Pancake box robot and the Site Marking attachment through ten flag deliveries for Mission 15.
This is not the standard video lesson. We have always wanted to just destroy the field and see how easy it would be. We would prepare a detailed lesson in the next few months, but this was one of the first tries on completely destroying the FIRST LEGO League Seniour Solutions field.
In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab.
How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition.
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.
In part one we build an attachment that uses a rubber band to solve a competition challenge. The rubber band was released with the use of a motor. In this video we are removing the dependency on the motor and you could use the motor for other missions.
The previous rubber bands video showed a way to trigger the rubber band without a motor. This video gives one more idea on how to lift an axle and in this way release the rubber band. Use the idea for you LEGO Mindstorms robot constructions.
Rubber bands in the LEGO Mindstorms sets are very handy when it comes to collecting objects, especially loops. The mechanism most of the time could work like this - an axle is pushed, a rubber band is released and a lever collects the loop.
The Gyro sensor in LEGO Mindstorms EV3 sets is new for the sets and we answer basic questions about its usage. The sensor detect when the whole constructions turns at a particular angle, but there are a number of gotchas in using it.
There are a few main challenges with box robots and in the following tutorial we would like to resolve them. Read on and let's see how we could do this.
