This page shows all the robotics tutorials listed without specific grouping. Each tutorial is short, on specific topic, has a video. Tutorials are structured in sequence in Courses.
The bench mission was a video tutorial that we recorded several times. It was really hard to get it 10 out of 10. The reason was the shear complexity of the mission. There are three things that should happen in this mission at once which was extremely difficult. What you will see in the tutorial is how this attachment behaves
Accuracy and consistency is the topic of this tutorial, as all 10 out of 10 tutorials are at FLLCasts. We use a robot build only from LEGO Mindstorms Robot Inventor parts and we accomplish the mission 10 out of 10 times. You will see how we use an active gear attachment to catch the wheel and pull it to the black circle, which accomplishes the mission
This video tutorial is about flipping tires. We are using a LEGO Mindstorms Robot Inventor and the missing is from FIRST LEGO League 2020-2021 competition called RePlay. In the video you will see how to approach the two tires and how to flip them with an attachment. Then they must be returned back to the black circle.
With this video tutorial we start the course for LEGO MINDSTORMS Robot Inventor and how to successfully program the robot for FIRST LEGO League robotics competition. It is good to have SPIKE Prime or EV3 for the competition. But if you happen to have Robot Inventor, don't be discourage. It is still possible to participate and accomplish a lot with the set.
This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.
This animated video tutorial demonstrate the use of a lift attachment to accomplish loops mission. It is a lift attachment with a circular motion
In this video tutorial we demonstrate an attachment that can accomplish Drop missions. A drop mission is when you have to move on the FIRST LEGO League field with the robot, reach a mission model, and drop a part in this mission model. First time we saw such missions I think was in FLL 2013. The attachment, the robot and the mission model could be build from a single LEGO MINDSTORMS Robot Inventor 51515 set. The mechanism for dropping works by releasing a lever when the attachment is pushed against the mission model. Check them out.
This animation demonstrate the use of an LEGO MINDSTORMS Robot Inventor attachment to lift a lever of a mission model. The mission model is the Power Switch mission model where you have to move the lever from one side of the mission model to another. The principle of the attachment is powerful and easy to implement for all kinds of missions.
Programming the LEGO MINDSTORMS Robot Inventor for FIRST LEGO League competitions involves learning how to turn left and right with the robot. There are not precise turns. The robot will make mistakes, because that's what robots do. But nevertheless it is important to learn how to program the robot to turn. We are releasing an additional course that is focused only on programming and how to make the robot consistent in its behavior, but in this tutorial we stop on turning
This is a live video tutorial of an inertia triggered attachment build with LEGO MINDSTORMS Robot Inventor. The attachment, the robot and the mission model are all built from a single 51515 set. The cool thing about inertia triggered attachments is that they are active and are activated without the use of any motors which means that you have the motors for the other missions at FIRST LEGO League competitions. In the tutorial we demonstrate and explain how such attachments works and how they could be used.
This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.
One of the easiest ways to improve the accuracy of LEGO Education SPIKE Prime robots is to use acceleration and deceleration when moving. This also applies to LEGO Mindstorms EV3 and LEGO Mindstorms Robot Inventor and generally to most robots that we know of. This tutorial demonstrates how acceleration and deceleration could be used and what improvement in accuracy and consistency you could expect. This is quite useful for FIRST LEGO League and other robotics competitions.
In this video tutorial we try to move forward with a LEGO Mindstorms Robot Inventor robot and we try to keep a straight line using the Motion Sensor. Without entering into the details of the programming we demonstrate what is the behavior of the robot when trying to keep a straight line with the Motion Sensor while we are participating in a FIRST LEGO League competition.
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.
With this first tutorial on the Motion Sensor in the LEGO MINDSTORMS Robot Inventor course we demonstrate the basic algorithm for moving in a straight line with the Motion Sensor. From here all the other algorithms are modifications, and if you know the basic it will be easier to tweak the behavior for your particular challenge
In this video tutorial we are demonstrating the impact of slow and fast acceleration on the robot. In the Scratch program there is an acceleration block for fast and slow acceleration. The robot behaves in different way. Let's explore them so that you know what to use for FIRST LEGO League competitions.
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.
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 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
Without the use of the sensors, make sure that you are at least using "set movement acceleration to slow". In this tutorial we will demonstrate why and how this helps us improve the accuracy and consistency of the robot.
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.
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 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.
In this video tutorial we continue the exploration of pinless attachments and how to add them and remove them in a quick fashion. We've done this for SPIKE Prime and for EV3 and we will provide some other references in the lesson in the course. The idea of an attachment below the robot is that sometime, during FIRST LEGO League competitions we have to bring a mission model from one place of the field to other. Basically push it.
Continuing from the last tutorial, we demonstrate the consistency and reliability of the robot when we don't user sensors. The result is pretty obvious - the robot is NOT consistent and reliable. It just makes a lot of mistakes
It all started with the famous 2017 mission for flipping a manhole and it was one of our favorite missions ever. Here in this tutorial we demonstrate the same principle of flipping a part from one side to the other. Sounds interesting, yes it is, yes it is.
