FIRST LEGO League (FLL) is the most popular LEGO Mindstorms Robotics Competition. Each year the season starts in Augusts and completes by May. We've created a lot of resources for FIRST LEGO League to help teams prepared, learn and have fun. Here are most of the tutorials, building instructions and courses for FLL
Here we collect resources that are common for most LEGO Mindstorms robotics competitions. The resources here could be used for FLL, WRO, general line following, sumo and many more.
Learn how to build LEGO robots and win the FIRST LEGO League competition.
Using LEGO Mindstorms EV3 and NXT robotics kits we give curriculum ideas, share professional experience and teach students to think and develop as engineers. The goal of this category is to group specific examples from specific missions.
Contains resources for LEGO Mindstorms competitions. There are many LEGO competitions using EV3, NXT and RCX robots. These competitions have some similarities, but could be quite different in general. Most popular are of course FIRST LEGO League and World Robotics Olympiad.
Need to transfer circular into a linear motion. You need a rack. Here is an attachment with a rack for our box robot.
In this video we are also focusing on lifting a loop as a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. We demonstrated an attachment for lifting a loop. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
In this tutorial we demonstrate how a loops mission could be accomplished with a Push/Pull Attachment. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This video is about a lever that should be pushed and this lever is connected to an axle. This means the lever should rotate. It is a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. The inspiration for this mission is the FLL 2012 Senior Solutions Oven mission. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
Lifting a loop is one of the most common missions in different robotics competitions. In this video we demonstrate how we could do "Vertical lift". It is suitable for precise lifting especially when the mission model requires you to lift straight up. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
We call active attachments those that are powered with a motor. This one is in the the mission of lifting levers which is common at robotics competitions like FIRST LEGO League/World Robotics Olympiad. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This quick pinless attachment is designed for collecting parts by pushing them. It shows the principle of putting a robot of an attachment in a very fast manner. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
The M08. AEROBIC EXERCISE is one of the very common types of mission in FIRST LEGO League robotics competitions. I think this pattern of missions was first introduced with the growing abilities of the participating students that were constantly reaching the maximum number of points. So the competition introduced mission that require a lot of time - 20-30 seconds, are time consuming and are complex. They requires a lot of moves. This here is a video tutorial on how it could be accomplished
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.
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.
10 out of 10 is our favorite series of video tutorials and in this one we are looking at the FIRST LEGO League 2021 RePlay competition and the tire flip mission. The goal of the mission is to flip a tire. Two tire. Perfect. We manage to do it each and every try
In this video tutorial we accomplish the Cell Phone mission from the FIRST LEGO League robotics competition, season 2020-2021. The goal of the mission is to flip a phone. There were a couple of missions in the past with one important mission in 2017 that was very similar. It is a 10 out of 10 tutorial which means we accomplish the cell phone mission every time.
Step Counter mission model is one of the more interesting mission models at the FIRST LEGO League 2020 RePlay competition. There is a locking mechanism that does not allow us to just push on the mission model to accomplish it, you must push it really slow and to do this 10 out of 10 times it is challenging.
This is a 10 out of 10 video tutorial that is different from the rest. We demonstrate how difficult it is to accomplish a mission and we use an attachment that is working 5 out of 10 times. Our goal with the video is to give everybody the understanding that taking your time to accomplish a mission is the right thing. Most of the 10 out of 10 tutorials at FLLCasts contain solutions and approaches that are working in a repeatable fashion. Not this one. See how difficult it is to accomplish a mission and that we also make mistakes.
In this FIRST LEGO League video tutorial we accomplish the Step Counter mission from the FLL 2020 RePlay mission. The mission model is quite interesting as it can not be pushed fast and it can not be pushed slowly, because it will jam. The robot must push it with the right speed and this proves to be difficult.
In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.
This video tutorial is for the Tire Flip Mission from FIRST LEGO League 2020 RePlay robotics competition. Flip missions are always some of the most interesting and challenging. In this tutorial you would learn how to build an attachment and accomplish a mission that requires you to flip a part, like flipping a coin. Most of the complexity for this mission is in the attachment and not the programming, but this is also way it works perfectly, every single time.
This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.
