Mission 7 looks playful in a single run; ten attempts show how much it depends on the table. In this FLL 2025 UNEARTHED competition test, the Smaller Pancake box robot uses the Heavy Lifting attachment after aligning against the wall.
Съединителят е механично устройство, което предава или не предава въртеливо движение. Днес ще видим как можем да конструираме такъв елемент, като използваме ЛЕГО.
This is not the usual straight trip from base to mission model. For Mission 7: Heavy Lifting in the FLL UNEARTHED season, the Smaller Pancake box robot deliberately travels outside the mat, uses the table wall as a reference, and reaches the Millstone with an active pinless attachment.
The after season review continues. No. We are not publishing a single solution for the next season before it is over, but let's learn from the previous season. The current tutorial is about three missions at once on a single run with the robot. Most FIRST LEGO League teams try to accomplish one-two missions on a single run out of the base, and three is really what makes the difference
The hook can be engineered perfectly and still miss if the robot begins at the wrong angle. This ten-run analysis of Mission 9: What's on Sale in the FIRST LEGO League UNEARTHED season follows the Smaller Pancake box robot with its roof-and-market attachment.
DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways.
A rotating hook does most of the heavy lifting in this solution for Mission 9: What's on Sale in the FLL 2025 UNEARTHED competition. The Smaller Pancake box robot uses the gear-driven M09 attachment to raise the roof, release it cleanly, and lift the market wares during the same return movement.
Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.
Fast runs are only valuable when they survive repetition. This 10 out of 10 tutorial tests the Smaller Pancake box robot and the Tip the Scales attachment on Mission 10 in the FIRST LEGO League 2025-2026 UNEARTHED competition.
The LEGO Mindstorms EV3 set comes with two LARGE motors. But even though these motors look almost the same they are not quite the same. There are always some differences in their behaviour. If you have more than two motors, because you bought them or you won them somewhere at a competition, it is worth doing an experiment to find which pair of motors works best.
Rather than forcing the scale down, this solution lets gravity finish the job. In Mission 10: Tip the Scales from the FLL UNEARTHED season, the Smaller Pancake box robot uses a passive pinless attachment to lift the green cover just enough for the scale to tip, then catches the pan as it reverses.
You could use the LEGO Steel Balls as a third wheel on the robot. It is a caster wheel. But this is steel and as we know from basic existence on this planet, where there is steel there is also rust. The steel ball could get quite rusty and this could have an influence on the behaviour of the robot
Small variations in the approach do not always have to change the score. In this 10 out of 10 test from the FLL 2025-2026 UNEARTHED competition, the Smaller Pancake box robot repeats Mission 11: Angler Artifacts with the same geared attachment ten times.
The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts.
For Mission 11: Angler Artifacts in the FIRST LEGO League 2025-2026 UNEARTHED competition, the Smaller Pancake box robot does not simply drive into the model. With the geared Angler Artifacts attachment, it pivots into position, meshes with the mission gears, and raises both the flag and the artifact before heading toward the right base.
The robot can move with different speed by applying different power to the motors. It will most of the time make smaller deviations when it moves slower. But you can't just move with a power of 10 all the time. This is a way too slow especially for competitions like FIRST LEGO League or World Robot Olympiad. In this video tutorial I would like to discuss the balance between motor power and robot movement error, how does the battery influence the power of the robot and to conduct an EV3-G experiment that will record the values of the Gyro Sensor along with the current power.
Retrieving the artifact once is satisfying; doing it ten times without touching the supports is the real test. This FIRST LEGO League UNEARTHED season video puts the Smaller Pancake box robot and the Careful Recovery attachment through ten runs of Mission 04.
This video tutorial contains a detailed description on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called Emergency Walk, which I think is one of the most interesting missions ever in FIRST LEGO League competitions. Join me in for a short explanation.
Mission 04 leaves almost no room for a careless approach. In this tutorial for the FLL 2025 UNEARTHED competition, the Smaller Pancake box robot works with the Careful Recovery attachment to enter the mine, close around the artifact, and lift it clear of the fragile supports.
In the third run Nightbeast team solves Mission 04 - Crater Crossing and partly Mission 03 - 3D printing and Mission 014 Meteoroid Deflection:
Can a motor-free mechanism repeat a multi-mission run without adjustments? This 10 out of 10 tutorial follows the Smaller Pancake box robot and the Map Reveal and Mineshaft Explorer attachment through M02 and M03 in the FIRST LEGO League 2025-2026 UNEARTHED competition.
This is the first run of Team "Nightbeast", with which they solve M01 and M02 from FIRST LEGO League 2019 Into Orbit:
One attachment, two mission models, and a lot happening in only a few seconds. During the FLL UNEARTHED season, the Smaller Pancake box robot uses the M02 and M03 attachment to reveal the map, secure the third topsoil section, and send the minecart to the opposing team's field.
This is the fifth and the last run of the Nightbeast team. Robot goes out of the base, do missions:
and stays on the field. It's a common practice for the competitors to left the robot on the field after the last run. This allows them to do some important points at the end of the match.
Ten consecutive attempts reveal far more than a single polished run. In this FLL 2025-2026 UNEARTHED competition reliability test, the Smaller Pancake box robot and the Surface Brushing attachment take on Mission 01.
In the second run Nightbeast team solves different tasks from two missions - M05 Extraction and M06 Space Station Modules:
Four jobs are packed into one compact run for Mission 01: Surface Brushing in the FIRST LEGO League 2025-2026 UNEARTHED competition. The Smaller Pancake box robot uses the Surface Brushing attachment to settle against the model, clear both soil deposits, capture the brush, and return to base.
