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 short animation we demonstrate how the LEGO Mindstorms Robot Inventor Distance sensors could be attached to the robot and then use to stop at distance from a wall. This wall could be the border of the field or another mission model. We need an attachment, we need a sensor and we need the robot. In the live video in the lesson we enter into more details and explanations of how the sensor is used. Programs for the distance sensor are provided in the lesson and in the LEGO Mindstorms Robot Inventor Programming course we enter into more details about how to program the distance sensor
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.
10 out of 10 for the innovation project mission is quite interesting - move forward, return, move forward, return. In the tutorial you will see how we accomplish the mission every team and how the program is repeatable
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.
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.
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
This is a 10 out of 10 video recording about the FIRST LEGO League 2020 RePlay competition and the mission called Boccia Target. We are using LEGO Mindstroms Robot Inventor. The 10 out of 10 recording shows how reproducible the solution to the mission is. You will see a demonstration of a complex attachment that does 3-4 things at once - it alights, pushes, drops, which are all things that are commonly seen at FLL competitions.
In this video tutorial we demonstrate the importance of properly shielding and protecting the light/color sensors of your LEGO Mindstorms Robot Inventor robots. These principles generally apply for all kind of robots. The problem is that external light sources from the venue could change the behavior of the robot - like have you ever been to a competition venue where the lighting just makes the robot behave in different ways? - well this tutorial is for you!
The bench mission was one of the most difficult we've encountered, especially when it comes to accomplishing the mission reliably. The goal of the mission is to push the bench down, lift part of it and leave 4 boxes at specific places. The whole concept of the mission is awesome. Here is how we did it:
The Slide mission the FIRST LEGO League 2020 is about the LEGO Minifigures sliding down the slide and the robot bringing them back to base. We must somehow bring then back do base. Do we push them on the Slide? Do we pull them? Or we could lift them. In this video tutorial we decided to pull the minifigures, but there is a catch.
In this FLL video tutorial we accomplish the step counter mission. We use a LEGO Mindstorms Robot Inventor robot. The idea of the mission is to control the robot in a very precise way so that it could slowly push on the mission model and accomplish it. In the tutorial we demonstrated exactly this slow push, but in a different way.
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.
10 out of 10 tutorials are about accomplishing missions in a reliable and repeatable way. In this video tutorials we accomplish the Step Counter mission 10 out of 10 times. We can push on the mission model, but if we push too hard we would lock it and there is no way back. So we use a slightly different approach. Check out the video to see how.
In this video tutorial we accomplish the Pull-Up bar mission from the FIRST LEGO League 2020. This is a 10 out of 10 tutorial for demonstrating the accuracy of the robot and the attachment. What you will learn is how a two part attachment works.
This 10 out of 10 tutorials demonstrates how we can accomplish a flip mission with a LEGO Mindstorms Robot inventor in a repeatable way. We manage to flip the tires on almost every try. You will learn and see how the attachment works and is able to push and flip the mission models.
The goal of the Pull-Up bar mission is to have the robot pull up on the bar... ok.. wording. In this video tutorial we demonstrate an interesting attachment that helps the robot attach to the Pull-Up bar and hang there. How do we do this - with a platform, that brings the robot to the bar and then detaches itself from the robot
In this video tutorial we dance with the robot. The goal of the mission is to reach the specific place on the FIRST LEGO League field and to Dance. It is suitable for students that are new and it gives every team a chance to accomplish at least on mission on the competition.
