This is a 10 out of 10 video tutorial that demonstrates the consistency and reliability of the robot that accomplishes the Unlock Cargo Plane mission. The attachment is an active attachment with gear wheels. It has a single lever constructed from 2 beans and we use this attachment to push on the mission model.
If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"
This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.
Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?
What should you as a teacher know when the students are trying to achieve a program and robot attachment that could reproduce their behaviour 9 out of 10 times.
In this video we discuss the durability of the construction of LEGO robots and how do we make them more durable.
In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.
This video tutorial is part of the 10 out of 10 series at FLLCasts and we will demonstrate how to accomplish the FIRST LEGO League 2020 RePlay competition mission called Innovation Project. Our goal is to push the construction to the require place on the field. What you will learn with this tutorial is how to place a random construction in the base and push/pull it to a place on the field 10 out of 10 times.
This tutorial demonstrates how we accomplish 5 missions in a row with a single robot and three attachments. This is a true multiple missions run for the FIRST LEGO League 2022-2023 SUPER POWERED. We Drop parts, we pull from the Smart grid, we push a lever, we collect a few energy units and we deliver the dinosaur toy.
In this video tutorial, we demonstrate how to release the cargo of a mission model. This mission model is an Airplane. We have to push a lever down to release it. We use an active attachment with a gear wheel.
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
In this video tutorial the Chain Monster LEGO box robot uses a multi-purpose attachment to collect two elements from the FIRST LEGO League 2022-2023 SUPER POWERED field and these are the "water" units on the field. What's interesting is that the contain where the water units are stored could be closed and opened and this allows us to freely move while non of the water units are lost.
This is a 10 out of 10 tutorial demonstrating the consistency and reliability of a LEGO Education SPIKE Prime robot when the robot delivers a mission model to a specific position on the field.
In this video tutorial, the Chain Monster box robot accomplishes three missions in a single run from the FIRST LEGO League 2023-2024 MASTERPIECE Challenge season. The LEGO Education SPIKE Prime robot uses an active attachment to collect the mini figures, to push a lever, and to deliver the figures to their designated places. The robot starts from the red base and returns to the blue base, performing all these actions in less than 20 seconds - consistently and reliably.
In this video tutorial we deliver the Innovation project model from base to the cargo connect marker on the field. The goal of the mission is to deliver. The mission model is assembled before that.
Throwing/Shooting is a common challenge in FIRST LEGO League competitions and in this robotics video tutorial we are demonstrating an attachment that you can use to throw/shoot a ball. There have been missions for throwing balls like in bawling, or like in soccer/football. The attachment that we use relies on the properties of the plastics used for the LEGO MINDSTORMS Robot Inventor 51515 set - it bends and it throws.
Note for the teacher on making the construction more stable, more durable and using beams for this.
This animation demonstrates the use of a Grab Attachment build from LEGO Mindstorms Robot Inventor 51515 set. Many of the FIRST LEGO League missions could be accomplished by grabbing the mission model and the principles shown here is useful for mission models that look like a loop
This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of the Kriket robot when accomplishing the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery.
In this LEGO video tutorial we accomplish 3 missions with the Kriket box robot. A number of actions are performed like Lever, Lift, Drop, Pull, Align. This tutorials shows how to accomplish missions models that are closely positioned next to each other.
This is a 10 out of 10 tutorial where we deliver and drop precisely to complete a FIRST LEGO League 2021-2022 Cargo Connect mission. We reuse the same attachment as in other missions to demonstrate a reusable attachment.
This is a 10 out of 10 video tutorial for the Slide mission at the FIRST LEGO League 2020 RePlay LEGO robotics competition. In the tutorial we demonstrate how to accomplish the mission 10 out of 10 times. At FLLCasts we try to build the attachments to be as consistent in their behavior as possible possible. In this way you know how the attachment along with the LEGO Education SPIKE Prime or LEGO Mindstorms robot will behave.
Energy storage mission from FIRST LEGO League 2022-2023 is again a two parts mission where we have to drop a few energy units in the mission model, but we also have to pull part of the mission model. In this video tutorial we demonstrate how the Chain Monster LEGO box robot accomplishes this with a multi purpose attachment for box robots.
"Sometimes it works, sometimes it does not work" - this is the most common case in FIRST LEGO League competitions. In this tutorial, we demonstrate and discuss such a case where the first part of accomplishing the mission always works but the second part has about 60-70% success rate. The robot is not very consistent. Let's take a moment to see it and explain why so that we can resolve the problem in the next lesson.
This is the first part of accomplishing M03 Energy Storage with the Kriket Box Robot. In this tutorial we show how to Drop the energy units in the storage. The second part will focus more on how do we pull the element from below the energy storage.
In this video tutorial we demonstrate a robot attachment that could be used to lift loops and other objects. Almost every year there is a mission at FIRST LEGO League competitions that involve lifting and the principle is interesting. You can build the attachment, robot and mission model from a single LEGO MINDSTORMS Robot Inventor 51515 set and learn a principle of building an attachment for lifting.
