Video tutorials

In this tutorial, we add another mission to our current program. This mission is - hanging the Gecko from the FIRST LEGO League Animal Allies. 

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M08. AEROBIC EXERCISE. This again is a very interesting mission from the competition. We could learn a lot of basic principles in the field of robotics. This mission requires the robot do to something very fast and many times. 

We will cover the typical reasons why your robot is not moving at all.

Tips and common mistakes when connecting two beams together

The Load Cargo mission model could be accomplished by loading a cargo in a number of mission models on the FIRST LEGO League 2021-2022 Cargo Connect field. In this video tutorial, we load the cargo on the platooning trucks. In the previous one, we load it on the trains.

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

In this video tutorial we would look at the mission run for M05. EXTRACTION. The mission is to collect and return to base a number of objects that are located on the field. Initially when I first saw the mission I thought it wold be quite challenging to accomplish it, but at the end it is not that difficult. 

In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.

Use any blocks that you wish to solve the following task.

Do your best as a teacher to make sure students are expanding their vocabulary on every occasion.

The course is very suitable for students and you don't have to buy a new set for each student. You can group them, divide them, organize the use of the sets and you could technically work with 70-80 student with only 6 sets. 

Here is the task for adding a beam on both sides of every gear wheel in your attachment.

Implement a program for stopping at a black line with the blocks containing the implementation details for the InitArray, Calibration and Getting the calibrated result. 

Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.

Once you start turning how to do you a whole 180 degrees turn. The robot almost does it, but not completely

Arduino programs are developed with a software and this software is downloaded from the http://arduino.cc site.

In the video we reach a conclusion. We have energy accumulated and to keep the system turning we need about 1J of energy each second to keep it turning.

Robotics Game of Life – that’s the name of our new scientific journey. We are organizing a 14-sessions course (1 session weekly). The idea of the course is to develop a solution to the Conway Game of Life where the robots would actually play the game. Students will construct the robots by instructions and lots of imagination. Initial programs will be provided by us and modified by students. 

The energy accumulated in the construction is about 2-3 Joules. In this first video we ask the question "How can we keep the energy in the system". How many Joules of energy should we input from the motor in order to keep the energy in the system.

In this video tutorial we show how you can build robots that position on the field consistently and reliably by following and line and then aligning to a line. We also demonstrate the concept of "double align" which is quite powerful and even if there were some mistakes they will be handled.

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.

If we wish to check if two sprites touch eachother or a specific sprite is touching something on the screen, the easiest thing to do would be to check the color! Now you will findout how to do this.

We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.

We got the speed of rotations of the motor in Radians per second. Let's calculate the value for the speed of the whole system. We calculate that the wheels are rotating with 375 radians per second. Which is impressive and quite fast for this system. From this speed, knowing the inertia mass we can calculate how much energy is the system accumulating. 

In this video tutorial with LEGO SPIKE Prime we accomplish M02 Oil Platform from the FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. We use the Kriket box robot and an attachment that allows us to lift. The actions of the mission is between Lift and Push, be because it is vertical.. we choose Lift. Checkout the full tutorial for all the 3 missions in a single run.

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.
