In this video we discuss the durability of the construction of LEGO robots and how do we make them more durable.
One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.
A common question is how to display arrays on the LEGO Mindstorms EV3 brick screen. Displaying values from an array is not different from any other display operation. In this tutorial, we would look at displaying two specific values. The minimum and the maximum for a specific sensor from the Advance Calibration Course Section
In this video tutorial we look at Vertical Lift Attachments. The attachment, the root and the mission model are all build from LEGO MINDSTORMS Robot Inventor 51515 set. We've found that vertical lift attachments that could lift missions models vertically could be quite useful for FIRST LEGO League competitions. This attachment is one of the more complex attachments and some say it has an "eye opening" mechanism as you can learn so much from it. It uses gear wheels and two levers connected to those gear wheels to lift a part vertically.
This video tutorial is part of the 10 out of 10 series at FLLCasts and we will demonstrate how to accomplish the FIRST LEGO League 2020 RePlay competition mission called Innovation Project. Our goal is to push the construction to the require place on the field. What you will learn with this tutorial is how to place a random construction in the base and push/pull it to a place on the field 10 out of 10 times.
Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
In this tutorial, we show you how to display all the values from an EV3-G array on the EV3 brick display. We are using an array Read Operation along with a loop. We are also detecting the loop counter and using it as an index to an array. It's basically the only viable way to do it. The process is commonly referred to as - "Iteration over an array" (although we still do not have an iterator in the programming language, we promise that one day we would do the super advance videos on "iteration" using the LEGO MINDSTORMS robots")
Note for the teacher on making the construction more stable, more durable and using beams for this.
Throwing/Shooting is a common challenge in FIRST LEGO League competitions and in this robotics video tutorial we are demonstrating an attachment that you can use to throw/shoot a ball. There have been missions for throwing balls like in bawling, or like in soccer/football. The attachment that we use relies on the properties of the plastics used for the LEGO MINDSTORMS Robot Inventor 51515 set - it bends and it throws.
This is an animation of a quick pinless attachment that is placed below the robot and is used to deliver parts, like the Container Mission model, to different parts of the field. In the live video in the lesson we explain more about the principles, while here in the animation you can get a quick overview of how it works and you can try to follow the same principles for an exercise.
This video tutorial contains a details explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M06. SPACE STATION MODULES. This again is a very interesting mission from the competition from which we could learn a lot of basic principles in the field of robotics.
Following the principles from the previous video, try to make the attachment that you've built, more stable and durable.
This is a 10 out of 10 video tutorial for the Slide mission at the FIRST LEGO League 2020 RePlay LEGO robotics competition. In the tutorial we demonstrate how to accomplish the mission 10 out of 10 times. At FLLCasts we try to build the attachments to be as consistent in their behavior as possible possible. In this way you know how the attachment along with the LEGO Education SPIKE Prime or LEGO Mindstorms robot will behave.
In the previous video, we found the correct answer for our task and it is 18.75, or is it?
In this video tutorial we demonstrate a few ways to use the Distance sensor from the LEGO Mindstorms Robot Inventor on FIRST LEGO League competitions. We don't enter into the details about programming as we do in the LEGO Mindstorms Robot Inventor Programming course, because here we demonstrate the behavior of the robot when the sensor is use and we make the argument that you should always use sensors at FIRST LEGO League competitions
In this video tutorial we accomplish a robotics competition mission model and we accomplish it 10 out of 10 times. The mission is Pull-up from the FIRST LEGO League 2020 RePLAY competition. The goal of the mission is to pull up the robot on the bar. The robot must not be touching the ground.
In this video tutorial we accomplish the Innovation project mission from the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to build a new construction on the day of the competition and to complete a mission with this new construction. There are a couple of spare parts in the FLL set and building the construction for the innovation project was quite fun.
This animation demonstrates the use of a Grab Attachment build from LEGO Mindstorms Robot Inventor 51515 set. Many of the FIRST LEGO League missions could be accomplished by grabbing the mission model and the principles shown here is useful for mission models that look like a loop
In this video tutorial we demonstrate the user of a quick 'pinless' attachment. As all pinless attachment it is not that they are completely pinless, but that they do not require the "click" of the pins that is often difficult to achieve in a quick pace environment as during FIRST LEGO League competition rounds.
In this video tutorial we demonstrate a robot attachment that could be used to lift loops and other objects. Almost every year there is a mission at FIRST LEGO League competitions that involve lifting and the principle is interesting. You can build the attachment, robot and mission model from a single LEGO MINDSTORMS Robot Inventor 51515 set and learn a principle of building an attachment for lifting.
In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.
10 out of 10 is our favorite series of video tutorials and in this one we are looking at the FIRST LEGO League 2021 RePlay competition and the tire flip mission. The goal of the mission is to flip a tire. Two tire. Perfect. We manage to do it each and every try
In this LEGO robotics video tutorial we will accomplish mission 8 from the FIRST LEGO League 2020 RePlay competition. The name of the mission is Boccia. What you will learn from the video is how to accomplish complex missions that require following a line, aligning to the line and accomplishing many mission models in a single run
In this video tutorial we demonstrate the behavior of a LEGO Mindstorms Robot Inventor robot when we use the Motion sensor. The Motion sensor was also referred to as Gyro sensor in previous versions of the LEGO Mindstorms Robot. We do not enter into the details of the programming and you can download the programs from the course lesson, but we make a demonstration of how the robot turns to about 95 degrees when we try to turn it to 90 degrees, we explain why and we suggest a way to improve the behavior of the robot.
This video tutorial is about accomplishing the Pull-Up bar mission from the FIRST LEGO League 2020 RePlay robotics competition. The goal of the mission is to move with the robot and pull the robot up. With this video tutorial you will learn how to build such attachments and how missions that are about lifting the whole robot could be accomplished. The attachment also makes a very good use of rubber bands.
