On of the most precise ways to position on the FIRST LEGO League and other competition fields is to follow and align and in this tutorial we demonstrate exactly this - how consistent and reliable this method is to reach specific mission models. In this way you know that every time you will be at the right place, which is great.
In this 10 out of 10 tutorials we do 10 runs that demonstrated how consistent and reliable it is to stop at the second intersection. This is useful as it is one of the main ways to figure out how to position yourself on the field.
Every time we start the robot we want to start from the same place, not only in terms of where we are on the field but also in terms of how are the motors rotate. The motors have an internal sensor for detecting the rotation. Because of this they know how rotated they are. It is a very good practice to always reset the motors before we start a competition run especially at FIRST LEGO League or World Robot Olympiad competitions
This is the first video tutorial from our course on LEGO MINDSTORMS Robot Inventor programming. In this tutorial we will start with how do we move without sensors. We will demonstrate a simple program. Our hope with this tutorial is that you will see why moving without sensors is a bad approach.
We will cover the typical reasons why your robot is not moving at all.
This is the most basic line-following method, commonly known as the "ducky" line-following method.
There are many cases in programming where you want something to repeat indefinitely. Here's how to achieve that!
The main difference between this field and the easier one is the addition of crossroads. Crossroads introduce a new level of difficulty that can be overcome by programming the robot to remember the paths it has taken, although there are simpler and more elegant solutions.
For this challenge, it is assumed that the field layout is unknown before the competition, making it impossible to hardcode a specific sequence of turns.
This video tutorial demonstrates how the MiniBox accomplishes four missions - M06, M07, M14, and M15 - of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition.
It may seem challenging to achieve all of this in a single run, but with careful planning and solid programming, success is within reach! The robot is a LEGO Education SPIKE Prime box robot, equipped with rubber bands and various mechanisms. Since this is our final run, we can leave the robot on the mat, saving some time. Let's dive in!
