We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.
The Department of "throwing" is ruled by rubber bands. Impulsive power release in a short amount of time. In this video we are building an attachment that throws a ball and accomplishes the FIRST LEGO League 2012 bowling competition.
Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container.
Try to build the attachment following the instructions. Use it to actually solve a mission from any competition (like taking loops)
Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.
SIngle robot attachment, many points.
This is part one of an FLL 2020 attachment used to accomplish the pull-up bar mission. This is the part of the attachment that stays below the robot. We put the whole robot on this attachment and we move. It is an interesting approach because as we move to the pull up bar this attachment detaches itself from the robot.
This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.
In this video tutorial we demonstrate an attachment that can accomplish Drop missions. A drop mission is when you have to move on the FIRST LEGO League field with the robot, reach a mission model, and drop a part in this mission model. First time we saw such missions I think was in FLL 2013. The attachment, the robot and the mission model could be build from a single LEGO MINDSTORMS Robot Inventor 51515 set. The mechanism for dropping works by releasing a lever when the attachment is pushed against the mission model. Check them out.
Activate the heavy lifting attachment with a Scratch program
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, we carry, deliver and drop a large object with an attachment that is much more stable than the basic. We get out of the base, and we actually carry the model. This attachment is also auto-correcting as it has a guiding beam at the front, and even when the robot makes a mistake, we can successfully accomplish the mission.
In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.
This is a 10 out of 10 tutorial, where we demonstrate the consistency and reliability of an attachment activated when we reach the mission model. We do not use a motor. We activate the attachment by pushing the robot to the mission model of the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery Mission.
This is a 10 out of 10 tutorial on a basic approach for one of the unique challenges in FIRST LEGO League competitions. This basic approach to a solution is not very consistent, and in some of the next tutorials, we will present a new solution. But we decided to record it to demonstrate how reliable this attachment is when it comes to carrying large objects. That could give you ideas of things to avoid.
In this video tutorial, we demonstrate the accomplishment of three missions in a single run. The competition is FIRST LEGO League 2022/2023 SUPERPOWERED and the missions involve carrying and delivering a dinosaur toy, delivering energy units, and delivering the innovation project model.
In this video tutorial we accomplish the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery. We demonstrate how 3 missions could be accomplished in the single run and in the same time with a single attachment.
This attachment is part of a second version of attachments for accomplishing the M07, M08 and M15 where we have to push and collect in the FIRST LEGO League 2022-2023 competition. It is for the Kriket Box Robot and we are doing this second version to make sure there are enough examples of how to use the Kriket box robot.
The interesting part about this attachment is how it connects to the robot. The Kriket has two brown axles that are connected to the motors via a gear mechanism. The attachment is attached to these brown axles which transfer the motor movement to the attachment.
This attachment accomplishes three missions from the FIRST LEGO League MASTERPIECE. It is for the Chain Monster Robot. It accomplishes Mission 10 - Sound Mixer. It also partially accomplishes Mission 14 - Audience Delivery.
In this course, we demonstrate and explain example solutions for the FIRST LEGO League 2023-2024 MASTERPIECE competition using the MiniBox box robot as a base, with custom-built attachments. Every year, we share our solutions and insights only after the season is over. The course is unique in its focus on multi-mission runs, showcasing runs that accomplish 3, 4, and even 5 and 6 missions. We then dive into the details of each specific mission. As you follow the course, try replicating the solutions to better understand the programs and explanations. This approach teaches students and teachers the principles of accomplishing missions in FLL robotics competitions and how to help your team score more points. Moreover, with the MiniBox, you will definitely have fun leaving the attachments on the mat. That will save you some precious time preparing for the next run!
Before starting this course, we recommend reviewing the FIRST LEGO League robot game guide.

The offset beam creates a hook-like motion when rotating the gear, making "hooking" in loops an easy task.

This attachment is designed to detach, once it completes its purpose. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.
