The field in the game of life could be finite or infinite. It is interesting to see and learn how an infinite field behaves and works. 

In this episode I would like to show you how to enable the communication between the computer and the NXT brick, through the USB and using the leJOS project. Starting leJOS on Windows is pretty easy. But starting the samples and achieving the communication is the actual problem.

This is a 10 out of 10 tutorial on accomplishing M04, M05, M14, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. The robot needs to accurately drop the mini-figures and the Masterpiece mission model, then rotate the Augmented Reality Statue to reveal its experience—efficiently and predictably, 10 times in a row. The robot is the MiniBox, a LEGO Education SPIKE Prime box robot with several attachments.

In this video tutorial, we are accomplishing three missions in a single run from the FIRST LEGO League MASTERPIECE season. We are using our new out-of-box LEGO Education SPIKE Prime robot, called Kufar. Have you used such robots? No? Well, let's dive deeper in the construction of out-of-box robots and see how convenient and user-friendly they can be. Take one brick with a couple of sensors and let your imagination run wild as you create the most inventive attachments.

This 10 out of 10 tutorial is a complete uncut recording and it shows how the Chain Monster box robot accomplishes 5 missions in a single run and it does this 10 out of 10 times. It is from the FIRST LEGO League 2022-2023 robotics competition.

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.

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.

The power in the car comes from the batteries. The batteries are in a batteries holder. About 5 of them. Two cables are connected to the batteries holder. It is very important to identify which of those cables is the plus and which is the minus.

Present the details

Take the hacksaw, the drill and let's cut the pipe.

From programs that rely entirely on proportional line following to those that use a PID-type program where "P" stands for the proportional line following component, proportional line following has proven to be a core mechanic in line following competitions.

10 out of 10 tutorials for the Slide mission was a challenge. There were a lot of glitches with different attachments that we built. At the end we have an attachment that is able to reliably pull the mini figures up, then forward,then down which.

In this video tutorial we accomplish the Boccia mission from the FIRST LEGO League 2020 RePlay competition. We use LEGO Mindstorms Robot Inventor robot. In this mission we use an attachment that does three things in the same time - align, push one lever and drop a couple of boxes in a target. It is a complex attachment and it is worth the watch.

In this video tutorial, we demonstrate a configurable attachment used for accomplishing a FIRST LEGO League 2021-2022 Cargo Connect mission called Sorting Center. The mission model has three cargo objects that are placed randomly. The attachment is configured before the run based on the configuration of the cargo objects. This attachment is also very powerful as it aligns and auto-corrects the errors that the robot is making by squaring the robot.

This is a 10 runs tutorial that demonstrates how the accuracy of the robot improves when we use slow acceleration vs fast or default acceleration. Note that the improvement is small. This is not an accurate and consistent robot. No. This is a robot that is all but accurate or consistent. It does not use sensors and you should use sensors. But it is a teaching/demonstration moment for everybody to seen what is it that you can expect if you don't use sensors.

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.

Similar to the tutorial for the LEGO Education SPIKE Prime this tutorial again accomplishes the cell phone mission. The mission is to flip the phone and is part of the FIRST LEGO League 2020 RePlay competition.

This is a true 10 out of 10 video tutorial. The robot accomplishes the Weight Machine mission from the FIRST LEGO League 2021 RePlay competition every single time. The attachment demonstrate a mechanism that performs and is stable on every try

The task is to find what the best seed is that will live the longest without entering into a loop or without dying. Find it and submit in the tasks section.

In this 10 out of 10 tutorial, we accomplish the Platooning Trucks from FIRST LEGO League (FLL) 2021-2022. The goal of the mission is to connect the trucks to each other and both of them to the bridge. The attachment and the robot pushes the trucks and we do it 10 times to see the consistency and reliability of the robot.

In this video tutorial we discuss probably the most useful principle that we've found for FIRST LEGO League competitions and this is how to align to a line with two color sensors. We use the LEGO Mindstorms Robot Inventor for a quick demonstration of the principle. In the LEGO Mindstorms Robot Inventor Programming course we enter into more details of how exactly we program the sensors. The current tutorial demonstrates the use of such a program and makes clear why this could be very useful and is a must for any well prepared team and wants to achieve a good score on the competition.

The goal of the Innovation project mission is probably to give everybody an easy win on the competition. A mission that does not require an attachment or a complex program and it the same time is quite interesting. In this video tutorial you will see our robot and our innovation project construction, along with how we complete the mission. Hope you like them!

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.

The robotics tutorial is about the shape of the pipe its advantages and disadvantages.
