This video tutorial demonstrates again the consistency of the program for aligning to a line. We run it ten time. We the robot is always coming from the left it is always arriving at the same position. When it is coming from the right it is always arriving at the same position.
When aligning backward the robot is still very consistent. It does not matter the direction in which we align. What you will learn from this tutorial is what is the consistency and reliability of the robot that you could expect.
In this video tutorial, we accomplish a FIRST LEGO League mission called The Bridge. We demonstrate how to use a really simple active attachment where the goal of the mission is to push down both parts of the bridge. We do not enter into the programming and we leave it up to you as an exercise.
You’ve probably seen a spinning fan or display with LED lights that forms text or images in mid-air — it looks like magic! But what’s really happening?
This amazing effect is based on a concept called Persistence of Vision (POV). When an LED strip spins fast enough and its lights turn on and off at just the right times, your brain blends those quick flashes together. The result? You see a complete image - even though it’s really just a single line of lights moving in circles!
In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.
This is the 10 out of 10 version of executing 3 missions in a single run. It worked like a charm! 10 times. We push and collect energy units for the FIRST LEGO League 2022-2023 SUPERPOWERED Challenge competition.
In this video tutorial, we demonstrate an attachment that is activated when we reach the mission model. That means the attachment is not activated by a motor but by the movement of the robot. We accomplish the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model, where we have to move and bring cargo to the mission model and leave the cargo there.
Tips and common mistakes when connecting two beams together
We are working on the World Robotics Olympiad (WRO) 2013 competition and its elementary part. The series will introduce three different concepts and this would be Arrays, Menus and Counting different lines. In the video you will see the robot working as it is in the final stage.
An interesting question that has arise is whether we can use the LEGO Mindstorms EV3-G Software to program the NXT brick. In this episode we will go through the blocks from the EV3-G Software and see which works with the NXT Hardware and which does not.
We dispay the speed of rotation of the wheels on the brick screen. We use the math blocks to do a proper calculations from rotation to radians per second. Knowing the speed, the radiuses and the mass of the wheels we find energy in Joules accumulated in the construction.
We show the principle of solving the next FIRST LEGO League (FLL) Nature's Fury 2013 competition missions. Again, without any programs, but just the principles of using one attachment for most of the missions.
