Second version of a reusable gear attachment. This time the black gear wheel is at the top. It is useful when you are constrained by space.
Third version of a reusable gear attachment. In this scenario a single motor could power two different axles in two different directions. If you use it to accomplish a mission do not forget to send us a video. We would love to see it.
Forth version of a reusable gear attachment. Again, it powers two axles and this time there is a lever connected to one of the axles.
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.
LEGO Attachment user for throwing/shooting a ball. It is powered with one motor and uses the fact that the parts of the LEGO set could bend. Build and experiment with it. Many FIRST LEGO League competitions have missions that could be accomplished with attachments that throw/shoot
It all started with the famous 2017 mission for flipping a manhole and it was one of our favorite missions ever. Here in this tutorial we demonstrate the same principle of flipping a part from one side to the other. Sounds interesting, yes it is, yes it is.
This flip attachment from LEGO MINDSTORMS Robot Inventor 51515 set is design to flip parts. It can flip a manhole for example, but could also flip other parts. The principle of flipping is quite interesting as it uses two axles and a border.
In this video tutorial we look at Vertical Lift Attachments. The attachment, the root and the mission model are all build from LEGO MINDSTORMS Robot Inventor 51515 set. We've found that vertical lift attachments that could lift missions models vertically could be quite useful for FIRST LEGO League competitions. This attachment is one of the more complex attachments and some say it has an "eye opening" mechanism as you can learn so much from it. It uses gear wheels and two levers connected to those gear wheels to lift a part vertically.
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.
This is an attachment for the top of the robot and the attachment is used for lifting different parts. It is reusable as we could change the lever and use the attachment for a number of different missions.
This reusable attachment could easily be placed on the side of a LEGO MINDSTORMS Robot Inventor robot and accomplish different missions that require the robot to interact with mission models. It uses gear wheels.
This attachment demonstrates the principle of dropping a part inside a container. It uses parts only from the LEGO MINDSTORMS Robot Inventor 51515 set. The goal of the attachment is to release a lever that is holding the wheel.
This is a heavy lifting attachment and it can lift mission models vertically. It is build entirely from LEGO MINDSTORMS Robot Inventor 51515 parts. This is one of the more complex and interesting attachments that we demonstrate in the course and it show how a few gear wheels and levers could be used to change the motion from circular to linear. This is powerful concept that could be very valuable during FIRST LEGO League competitions.
Activate the heavy lifting attachment with a Scratch program
We use this attachment to demonstrate the principle of an active attachment. This is an attachment activated from the motor. It has one level attached to it. It could be reused. The attachment transfers power from the motor to the end of the lever and we can accomplish missions like the Power Switch mission from the FLLCasts Off-season mission models.
In this video tutorial we demonstrate the user of a quick 'pinless' attachment. As all pinless attachment it is not that they are completely pinless, but that they do not require the "click" of the pins that is often difficult to achieve in a quick pace environment as during FIRST LEGO League competition rounds.
The goal of this course is to take you through some of the most useful principles for building and using attachments to accomplish missions at FIRST LEGO League competitions. The whole course is based on a LEGO MINDSTORMS Robot Inventor and you need a single 51515 set and without additional parts (you will need a second color sensor for the lessons for using two color sensors, but feel free to skip them if you don't have it). For every mission there is a Scratch and Python program attachment. The course consists of 25 lessons suitable for beginner and advanced students. Every lessons consists of a video tutorial demonstrating the principle and how the mission could be accomplished along with building instructions for the robot, the attachment and programs for controlling the robot.
This animated video tutorial demonstrate the use of a lift attachment to accomplish loops mission. It is a lift attachment with a circular motion
This animation demonstrate the use of an LEGO MINDSTORMS Robot Inventor attachment to lift a lever of a mission model. The mission model is the Power Switch mission model where you have to move the lever from one side of the mission model to another. The principle of the attachment is powerful and easy to implement for all kinds of missions.
This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.
