Video tutorials

In this video tutorial with LEGO SPIKE Prime we accomplish M02 Oil Platform from the FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. We use the Kriket box robot and an attachment that allows us to lift. The actions of the mission is between Lift and Push, be because it is vertical.. we choose Lift. Checkout the full tutorial for all the 3 missions in a single run.

This video tutorial focuses on M01, M02, and M14 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. The Chain Monster box robot (a LEGO Education SPIKE Prime robot) uses a single attachment to accomplish all three missions in sequence. First, it pushes the mission model, then presses down the next one, and finally collects some mini-figures.

In this video tutorial, we demonstrate how the Chain Monster box robot delivers minifigures for M14 and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition. The robot is a LEGO Education SPIKE Prime model, equipped with a special attachment for precise delivery.

M14 and M15 are part of larger runs, but in this video, we focus exclusively on these two missions. Let's dive in!

In the video we reach a conclusion. We have energy accumulated and to keep the system turning we need about 1J of energy each second to keep it turning.

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

This is a teacher's note about the math behind calculating gear ratios with for our lifting attachment. It math model we build in previous tutorials is not exactly correct and here is the explanation why.

Is it better to do fast turns or slow turns? Should you save some time by turning fast or should you be more precise by turning slow. Where is the balance? This video tutorial demonstrates exactly this for LEGO Education SPIKE Prime robot, their motion sensor and an ever occurring question on FIRST LEGO League competition which is how to find the balance and where is the balance.

This tutorial explains the use of motion and light/color sensors to accomplish a complex mission split into three parts. It gets into detail about how we keep a straight line with the motion sensor, follow a line with the color sensors, and transition between different parts of the program by aligning and detecting lines with the sensor. The goal is to get to a reliable and consistent behavior of the robot. On top of that, it is configurable, as we've left a few parameters that could be set to configure the behavior for a specific robot, venue, lighting, battery level, and wheels friction.

In this video tutorial we continue the exploration of pinless attachments and how to add them and remove them in a quick fashion. We've done this for SPIKE Prime and for EV3 and we will provide some other references in the lesson in the course. The idea of an attachment below the robot is that sometime, during FIRST LEGO League competitions we have to bring a mission model from one place of the field to other. Basically push it.

In this video tutorial we demonstrate a Grab attachment build from LEGO Mindstorms Robot Inventor 51515 set. The goal of the grab attachment is to accomplish the mission of bringing loops back to base without loosing or dropping them when returning. The principle of the grab attachment also demonstrates how to have a a locking mechanism. In this way there is not way to the loop to escape.

The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever. 

This short animation demonstrates a really useful principle for FIRST LEGO League competition and this is how to use the Inertia of the robot to trigger an attachment that will do the work for us. It is very useful as we don't have to use the motors of the robot and we can afford to use the motors for other things.

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.

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.

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.
