In this video tutorial we accomplish the Cell Phone mission from the FIRST LEGO League robotics competition, season 2020-2021. The goal of the mission is to flip a phone. There were a couple of missions in the past with one important mission in 2017 that was very similar. It is a 10 out of 10 tutorial which means we accomplish the cell phone mission every time.
In this LEGO robotics video tutorial we accomplish Weight Machine mission from the FIRST LEGO League 2021 RePlay robotics competition. The goal of the competition is to lift a weight. The mission model resembles a weight machine, and is actually a lever. There are three different levels and you earn different points depending on the level. The attachment for this mission model uses rubber bands and lifts the mission model.
How far will the robot move for one second?
We are showing the basics of communication between LEGO Mindstorms NXT Bricks using a Bluetooth connection. In the next few minutes we will build two programs - one for the master and one for the slave brick, while explaining the essentials for building such programs.
Starting leJOS might be very problematic, since you need to install a few libraries and make some configurations. In this video tutorial I am showing a step-by-step guide on how you could install leJOS on your Ubuntu Linux. And it is quite easy.
This is a tutorial with 10 runs - 5 of them are slow and 5 of them are fast and we measure how accurate the robot is each time. How consistent is it? Can it arrive consistently on a specific location on the field without the use of the sensors? The quick answer is - No, it can not. But let's see it life
This short animation demonstrates a really useful principle for FIRST LEGO League competition and this is how to use the Inertia of the robot to trigger an attachment that will do the work for us. It is very useful as we don't have to use the motors of the robot and we can afford to use the motors for other things.
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.
The Cell Phone mission is part of the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to flip the Cell Phone. In this video tutorial we use a LEGO Education SPIKE Prime robot to flip the cell phone. This mission is similar to the FLL 2017: How to accomplish Manhole Cover (08th) Mission in FIRST LEGO League 2017-2018.
Let's attach the ball storing pipe to the FTC robot. In previous tutorials, I've shown you the complete robot, but for this, I've removed the pipe and will show you how to attach it.
In this tutorial, we record an example of how to cut the pipe to the desired length with a hacksaw. Cutting with a hacksaw is very common during FIRST Technical Challenge Preparation
In this tutorial, we are controlling the FTC Tetrix robot with the two sticks of the same GamePad. The left stick is for forward and backwards, while the right stick is for left and right.
How to place the cup on the robot so that the challenge is challenging.
In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.
Attach an axle to the front of the robot. Find a similar one, or modify the FTC Tetrix robot to accommodate the new axle.
The more advanced task is to more in a polygon. This would require calculating the degree of each of the turns and RobotC is a language in which you could implement this math calculation very easily.
This is the first, but not the last video tutorial of the course where we reach a specific mission model in a consistent way. We use the Motion sensor and only some basic principles like turning to an angle. If we use the principles in this tutorial and then build an attachment for the mission model we will have a pretty consistent way of accomplishing the FIRST LEGO League mission
With this animation we demonstrate an example for a quick pinless attachment that could be used to collect loops. Loops is one of the most common missions at FIRST LEGO League competitions. We use the LEGO Mindstorms Robot Inventor set to build the attachment, the mission model and the robot. They are all from the same attachment. In the live video in the same lesson we enter into more details about the attachment and we describe its idea
10 out of 10 video tutorial for Rowing Machine mission from the FIRST LEGO League 2021 RePlay robotics competition. In the tutorial you will see how to accomplish the mission almost every time. This is a mission that requires a lot of precision so naturally it is difficult to accomplish it every time, but with the right attachment for the LEGO Education SPIKE Prime robot it is achievable
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.
In this robotics tutorial, we present a solution to extending a VEX IQ attachment to handle two hex balls at a time
In this episode I would like to show you how to enable the communication between the computer and the NXT brick, through the USB and using the leJOS project. Starting leJOS on Windows is pretty easy. But starting the samples and achieving the communication is the actual problem.
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.
Present the details
