By using the GamePad to control the arm with could lift it and return it back. The main problem with controlling the arm is that if you just use the motors you would hit the robot, bend the axles and breaks the gear wheels. We would use the distance sensor to make the arm move without hitting the robot.
Experiment with the software for about five minutes, before we even give you any directions.
Learn to program the Game of Life on the LEGO Mindstorms brick screen. This would require drawing on the brick screen, using blocks with switches and loops.
This animation demonstrates the principle of aligning to a line with two color sensors and a LEGO Mindstorms Robot Inventor robot. This is a useful concept for FIRST LEGO League competitions where you want to know exactly where you are on the field and to achieve consistent behavior. In the course lesson you will also find a live video tutorial where we enter into more details about aligning. We align the robot to a line by moving both sensors slowly until they both see a black line. When one of them sees the line we move only the other. At the end we return the first sensor back.
Overview of the big task that we want to achieve in this module.
Following the Advance Sensor Calibration course section, we found the min and max values detected by each sensor. Now it is time for the real deal of the calibration. Detect the current value from the sensor and find what is the percentage of this value for the range between min and max.
How to add a plastic plate to the FIRST Technical Challenge Robot build with Tetrix. The plastic plate is for collecting the balls. The plate should rotate and should be connected to the axle.
With the last few videos, we entered the math world. Why we do it and what to keep in mind
This LEGO robotics video tutorial is a 10 out of 10 run of the one of the most complex missions at the FIRST LEGO League 2021 RePlay competition. As the mission has three parts we are measuring the success rate of each part of the mission. What you can learn from this tutorial is how to achieve three missions in a single run including line following and a lot of aligning
What is a single, and what is two degrees of freedom
How to construct an axle with a plastic plate connected to this axle and make this plate rotate and collect balls.
Let's cover the break at end option and learn why there is no lesson about it to students.
The previous tutorial showed you how to copy/paste instructions in RobotC. The current video will introduce you to loops.
In this video tutorial we demonstrate how the robot could accomplish the Power Switch mission. Power Switch consists of a cube with a lever and the lever should be rotate to 180 degrees. This mission model was very close to a FIRST LEGO League 2012 competition mission which was called - Oven. The robot, the attachment adn the mission model are built form a single LEGO Mindstorms Robot Inventor 51515 set and with the tutorial you will learn how to use an active attachment with 2 gear wheels to complete such missions.
This robotics video tutorial is about the FIRST LEGO League 2020 RePlay competition and how we accomplish the Slide mission with a LEGO Education SPIKE Prime robot. The goal of the Slide mission is to collect two LEGO Mini figures and bring them back to base. We are demonstrating a simple attachment that collects 2 figures placed in an add way. The whole attachment must bring one of the figures up and then back.
We've just plugged in the power bank in the Raspberry Pi controller. Has it started? Is it doing something? Why is it not moving? Simply put the raspberry power a small red diode and it just emits light. Well, it's on, but it will do nothing else.
In this robotics tutorial, we would discuss the length of the pipe and its dimensions. These are general considerations for every container on a FIRST Technical Challenge competition.
The code is already ready. It is attached below the video. Let's see how the program works and what it does and how to use it.
How far will the robot move for one second?
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.
In this video tutorial we demonstrate a Grab attachment build from LEGO Mindstorms Robot Inventor 51515 set. The goal of the grab attachment is to accomplish the mission of bringing loops back to base without loosing or dropping them when returning. The principle of the grab attachment also demonstrates how to have a a locking mechanism. In this way there is not way to the loop to escape.
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.
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
