След като вече изпробвахте и се справихте с предизвикателство, включващо поредица от инструкции, искаме да ви представим някои добри практики.
Когато работите с ученици е важно да предадете очакванията си от тях в самото начало на курс.
Нещата, за които да внимавате като преподавател, докато учениците строят роботите си по инструкции.
In this video tutorial we focus on accomplishing a part of M08 of FIRST LEGO League 2023-2024 MASTERPIECE season. The mission is to lift and unlock the lever to make room for rolling the camera. It's a simple action but requires the robot to be stable and accurate. We use the Chain Monster - a powerful LEGO Education SPIKE Prime robot.
This videos tutorials demonstrated the robot accuracy in 10 runs one after the other. 5 of them are with the robot moving slow and 5 are with the robot moving fast. See for your self what is the accuracy achieved only with the move blocks of the robot.
After downloading the SPIKE programming software, you’ll need to connect to your hub in order to load a program to your robot. Let’s take a look at how you can do that!
This video tutorial focuses on M01, M02, and M14 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge. The Chain Monster box robot (a LEGO Education SPIKE Prime robot) uses a single attachment to accomplish all three missions in sequence. First, it pushes the mission model, then presses down the next one, and finally collects some mini-figures.
This tutorial demonstrates how a LEGO Education SPIKE Prime robot could stop when it reaches a wall. FIRST LEGO League competitions are held on tables that have border and it is sometimes useful to use the Ultrasonic sensor to detect the border and stop close to the border. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
In this video tutorial we take a look at the consistency of a robot that uses acceleration and deceleration to turn precisely. We use the motion sensor. In 10 consecutive runs we demonstrate what could you expect from the robot when it comes to consistency.
This is one of the last tutorials in the LEGO Education SPIKE Prime programming for Competitions course and it demonstrates what we've all been waiting for - how to reach a mission model from base in a reliable and consistent way when the mission model is on the other end of the field. Naturally what we use are all the different concepts that we've learned in the course and the tutorial is more advanced than the other so if anything is not clear take a look also at the different tutorials an concepts in the course.

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.
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.
This video tutorials shows how we accomplish a specific mission model from FIRST LEGO League 2022-2023 SUPER POWERED robotics competition. The mission is called - M11 Hydroelectic Dam and in the tutorial we accomplish part of it. In other tutorials when we get back with the SPIKE Kriket box robot we have more time to accomplish the rest of the missions.
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.
In this video tutorial we demonstrate how to accomplish M09 of FIRST LEGO League 2023-2024 MASTERPIECE Challenge. The robot is Chain Monster - a LEGO Education SPIKE Prime robot. It pulls the mission model and precisely positions it in the designated area. An interesting aspect is that the robot must rotate to position the loop correctly, so pay close attention when programming it.
In this video tutorial we demonstrate a really important concept for FIRST LEGO League competitions - you position the robot on the field with depending on timers and rotations. The issue with moving the robot for 10 seconds and then stopping is that every time it is in a different location. Same for rotations. The wheels will slip, the battery will change, something will happen and the robot will not be in the same place every time. This is not consistent and reliable.
On of the most precise ways to position on the FIRST LEGO League and other competition fields is to follow and align and in this tutorial we demonstrate exactly this - how consistent and reliable this method is to reach specific mission models. In this way you know that every time you will be at the right place, which is great.
In this 10 out of 10 tutorial we demonstrate the accuracy of the robot when we use acceleration in its movements. The robot has not sensors attached to it and it is not making use of it's internal sensors. The goal of the tutorial is to give you the understanding and to make a demonstration of how difficult it is to consistently reach a mission model without the use of sensor even when we use acceleration.
In this video tutorial, we demonstrate a full run of all missions without pausing the recording. The competition is the FIRST LEGO League 2023-2024 MASTERPIECE Challenge, and the robot is the Chain Monster - a LEGO Education SPIKE Prime robot.
These kinds of runs are extremely useful for team preparation right before the competition, as they help team members improve their accuracy, speed, and self-control.
With this 10 runs we demonstrate the consistency and reliability that could be achieved with a LEGO Education SPIKE Prime robot and a 2-states simple line following algorithm. It is not bad. Still there are some things you should consider when using this program and one of the things is the use of the timers
In this video tutorial we use the LEGO Education SPIKE Prime Motion Sensor to reach a mission model on the field. It's a basic use of the motion sensor that we will extend in the next few tutorials and in the same time we take the opportunity to demonstrate what a MyBlock is and how to develop one. As a result of this video you will learn how to make the program easier to read and maintain by organizing the blocks in the program in special MyBlocks that couple them all together.
On the topic of following lines with a robot there is a way to make the robot follow the line a little more precisely. This method is called "Multi-states" program. Or at least we call it like this. In this tutorial you will see how we program 5 state for the robot line following program. This could be particularly important with FIRST LEGO League competitions where we must build consistent and reliable robots.
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 the Chain Monster box robot accomplishes a mission that requires two actions. We should lift up (lever) and push almost at the same time on the mission model for it to release the batteries. These mission model is from the FIRST LEGO League 2022-2023 SUPER POWERED competition.
In this video tutorial we start with the basic of the basic, eg. how to move. We use the block from LEGO Education SPIKE Prime Word Blocks software. It is based on Scratch. The goal of the tutorial is to demonstrate how we can move and to teach something very important - the robot moves inaccurately
