This is a 10 out of 10 tutorial for a 3 missions run. The robot goes out of base and accomplishes 3 missions in a single run. It demonstrates the consistency and reliability of the robot and its program that uses sensors.
In a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise.
In this video tutorial we accomplish 3 missions from the FIRST LEGO League 2022-2023 SUPER POWER robotics competition. The three missions are wind turbine, television, rechargeable battery. The robot uses a program with sensor compared to the previous way we've accomplished the missions with the same robot.
Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot.
This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of the Kriket robot when accomplishing the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery.
The robot uses one middle motor. This middle motor with the use of a few gear systems controls for different axsels. We have attached wheels on this axles so it is very easy to extend the robot construction for additional LEGO Mindstorms active attachments
In this video tutorial we accomplish the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery. We demonstrate how 3 missions could be accomplished in the single run and in the same time with a single attachment.
In this video tutorial, we demonstrate the accomplishment of three missions in a single run. The competition is FIRST LEGO League 2022/2023 SUPERPOWERED and the missions involve carrying and delivering a dinosaur toy, delivering energy units, and delivering the innovation project model.
Positioning your MINDSTORM robot precisely on the FIRST LEGO League competition field is one of the first things you should learn while preparing. In this video tutorial, we will show three different attachments you could use when aligning to the walls of the competition table. We will show other ways and attachments in some of the next videos.
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 accomplish three missions in a row. It is a little longer and more detailed tutorial, but hey, 3 missions, one after the other. These are the Wind Turbine, where we have to push 3-4 times and collect the energy units, the Watch Television, where we reach the mission model and slightly push, and, of course, the Rechargeable Battery - where we collect the energy units.
This video is about a lever that should be pushed and this lever is connected to an axle. This means the lever should rotate. It is a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. The inspiration for this mission is the FLL 2012 Senior Solutions Oven mission. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This tutorial demonstrates how a robot moves forward in a straight line with the use of the LEGO Education SPIKE Prime Motion sensor. While the robot is moving we push on the robot at the back, simulating that "something has happened" and the robot then again returns back to the moving straight. To download the program check out the courses in which the tutorial is used.
Recap on the attachments, their purpose and how you should use them.
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.
In this video we discuss part of the pinless attachments build by the ELM team. Without pinless attachment it is nearly impossible to achieve a good score at the FIRST LEGO League competition.
In this video we are showing how to use two light sensors to do basic aligning on a black line. This is always needed at the competitions. We also show an example for following a line with two sensors.
In this episode we continue from Episode 55 and we improve the durability and stability of the attachment for a LEGO Mindstorms EV3 robot. Many times attachments are not very stable which results in gaps between parts. The goal of the video is to give basic construction ideas.
This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.
Rubber bands can be quite powerful. Based on several requests from you we are starting a series on using the LEGO Rubber bands available in the Mindstorms set.
In this video tutorial we will show you three ways for making your robot stable on the field. We will present each one of them with their advantages and disadvantages - it's up to you to choose which one is the best for your case.
This one is very special- an attachment that could lock itself on purpose while working.
Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons.
In this video we are solving one of the most important challenges on the FIRST LEGO League competition, i.e how to cover your Mindstorms NXT light sensors so that they are not affected by outer light sources at the day of the competition. Once again you would find 3 solutions and more will come in the next videos.
The way you move the robot is always imprecise. Don't TRY to fight with this. Programming motors for competitions like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) is not very different from programming the motors in the STEM classes. But there are a few things you should have in mind.
Enchansing a previous attachment, but only this time we are solving the FIRST LEGO League 2012 Medicine mission. There is a lever and a rubber band. When the lever is released the rubber band activates the attachment.
Let's try to integrate more of the things we have learned into a single attachment. One that could accumulate energy, conserve it and use it at the appropriate time. All this because of a Rubber Band and a Flywheel - and if you don't know what a flywheel is you should definitely watch this videos
