Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot.
This is one of the very interesting attachments by the ELM team. It is using rubber bands and some rubber to precisely drop the chicken. Very interesting way. Check it out and try to learn from it.
In the final video we explore how to trigger the release of the attachment with just a rubber band. The release is triggered with a gear wheel that rotates in a specific way. This saves speed, does not require additional LEGO Mindstorms motor and is precise enough for a competition.
This is the attachment of Team "Nightbeast", with which they do:
M11–Escape Velocity and M13–Observatory
The Observatory result depends on the model. Sometimes the pointer is in the orange area otherwise in the white area.
Accomplish three FIRST LEGO League missions at once. This is an interesting Large multi-purpose FLL attachment for a box robot that could be used to accomplish a number of missions with a single exit of the field base.
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.
This robot attachment in inspired by one of the most interesting missions we've seen at FIRST LEGO League competitions - the Manhole Cover (08th) Mission in FIRST LEGO League 2017-2018 . The attachment demonstrates how you could flip an object. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.
This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Pull-up bar mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.
An attachment designed for Heavy lifting. It's build with LEGO MINDSTORMS Robot Inventor 51515 and it has a gear wheels mechanism that allows you to increase the torque and lift really heavy things. Build the attachment and check out the tutorial. This will teach you one more principle that you could use for FIRST LEGO League competitions.
10 out of 10 video tutorial for Rowing Machine mission from the FIRST LEGO League 2021 RePlay robotics competition. In the tutorial you will see how to accomplish the mission almost every time. This is a mission that requires a lot of precision so naturally it is difficult to accomplish it every time, but with the right attachment for the LEGO Education SPIKE Prime robot it is achievable
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.
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.
This video tutorial demonstrates an attachment that flips a mission model. The mission model is attached to the field, but it contains a lever. This lever must be flipped from one side to the other. There is a switch. We use a pinless active attachment with gear wheels, and you can see how this works in the tutorial. There is no use of sensors as we don't need them. We will leave the alignment and positioning for some other tutorials.
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 passive attachment activated by the robot and not by a motor. It's used for accomplishing the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model.
In this video tutorial, we accomplish a FIRST LEGO League mission called The Bridge. We demonstrate how to use a really simple active attachment where the goal of the mission is to push down both parts of the bridge. We do not enter into the programming and we leave it up to you as an exercise.
In this part 2 of the LEGO video tutorial we accomplish the pull part of the M03 Energy storage from FIRST LEGO League 2022-2023 SUPER POWERED. Part 1 was about precise dropping, part 2 is about pulling as the model requires it
This FRIST LEGO League video tutorial is about he Boccia Share mission from FIRST LEGO League 2020 RePlay competition. In the tutorial we demonstrate how to push on a lever to release a mission model part - in this case a box. You have the choice before the competition to cooperate with the other team and to decide if you are going to do the blue or the red box.
A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.
This attachment is designed to detach, once it completes its purpose. Due to the way, the attachment is left on the mission model, it slides from, creating distance between itself and the mission model, therefore meeting the requirement that no attachment should be touching the mission model at the end of the competition. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.
A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.
This attachment is designed to keep the model from coming undone when dropped from a higher distance. It was done so that the robot could use a higher-position attachment to deliver the model while using lower-placed attachments to solve other missions in the same run.
In this tutorial, we share a tip for organizing robot attachments in the FIRST LEGO League challenge. By designing attachments to hook onto the table edge, you can keep them close at hand for quick swaps, saving time and reducing mistakes.
Options include building hooks into the attachment design or using small separate hooks. This method is used by many teams and is a practical way to stay organized during competitions.
