Take the hacksaw, the drill and let's cut the pipe.
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.
This video tutorial is about how to accomplish the Rowing Machine mission in the FIRST LEGO League 2021 RePlay robotics competition. The Rowing machine mission model consists of a wheel that should be pushed or pulled and will lift two other wheels, just like a real Rowing Machine. What you will get from this tutorial is an example of how to build a robot that is very precise. The attachment is simple, but the programming is more difficult. You must first align to a line, and then to a wall and then make a precise turn with the robot to accomplish the mission with our attachment.
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.
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.
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.
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 robotics tutorial is about the shape of the pipe its advantages and disadvantages.
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.
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
Control the hand of the FIRST Technical Challenge Push Bot robot with the GamePad bumpers.
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.
This FIRST LEGO League robotics video tutorial is about the Treadmill mission and how it could be accomplished. The mission is from FLL 2020 RePlay competition. Almost every year there is a mission of this type where the robot must spend a lot of time with the mission model in order to turn or lift something. These are quite interesting and challenging missions.
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 is a 10 out of 10 tutorial where we demonstrate a reproducible completion of a shared mission. The mission is shared as both teams must agree about how they are completing the mission. The tutorials shows the robot approaching the FIRST LEGO League mission model. You will see how the robot pushes on the lever every time for a 10 out of 10 completion.
How do you synchronise the two levers to move with the same speed, but in opposite directions?
On every FIRST LEGO League competition and generally robotics competitions with LEGO robots, we build attachments to accomplish missions and we must accomplish the missions in a limited amount of time. Most of the time we can not accomplish the missions with a single attachment and we have to change attachments. This is where building robot attachments that are easy to remove really makes sense. In this tutorial we discuss some of the things that should be considered in the building Easy to Detach modules and attachments
