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.
In this video tutorial, we carry, deliver and drop a large object with an attachment that is much more stable than the basic. We get out of the base, and we actually carry the model. This attachment is also auto-correcting as it has a guiding beam at the front, and even when the robot makes a mistake, we can successfully accomplish the mission.
Here you can find a cheat sheet with the most commonly used commands. There are also more advanced commands that are not included in the built-in API, but the available ones cover most, if not all, of the students’ needs.
Below is an example of a function definition and how to read it:
move_for_degrees(pair: int, degrees: int, steering: int, *, velocity: int = 360, stop: int = motor.BRAKE, acceleration: int = 1000, deceleration: int = 1000) → Awaitable
...
Parameters
pair: int
The motor pair to be used.
degrees: int
The number of degrees the motors should rotate.
steering: int
The steering value (from -100 to 100).
Optional keyword arguments:
velocity: int
The speed of the motor in degrees per second.
...
stop: int
Defines how the motor behaves after it stops. Use constants from the motor module.
...
acceleration: int
The acceleration in degrees per second squared (1–10000).
deceleration: int
The deceleration in degrees per second squared (1–10000).
Let’s take a closer look at the function definition:
The parameters before the "*" symbol are required parameters. You must provide them in the correct order. For example, the first parameter is "pair", so the command expects the motor pair first. The same applies to "degrees" and "steering".
The parameters after the "*" symbol are optional parameters. To change them, you must use their names. This means you cannot just write a number - you need to specify which parameter you are changing. For example:
motor_pair.move_for_degrees(motor_pair.PAIR_1, 360, 0, velocity=280)
Finally, the "Awaitable" keyword means that this command can be used with "await". This allows the program to wait until the command has finished before continuing with the next one. For example:
await motor_pair.move_for_degrees(motor_pair.PAIR_1, 360, 0, velocity=280)
The M07. SPACE WALK EMERGENCY is one of the most interesting missions in FLL the we've even seen. This video tutorial demonstrates a mission run for Mission 07 Emergency Walk in FIRST LEGO League 2018-2019 Into Orbit robotics competition. The tutorial contains only the mission run on the field. We accomplish a single mission.
In this course, you will work with other students in your group. These may be your classmates, teammates, or students you know from other activities. It is important to get to know your group so you can work well together.
Your teacher will introduce themselves first, and then you will get to know the other students in the group.
Remember your teacher’s name and address them by name.
Listen carefully to your classmates and pay attention to what they share. Show the same respect that you would like to receive.
Each student should share:
their name;
their age;
their grade;
the school they attend;
their favorite sport, hobby, or activity.
If your teacher allows it, you can also share a short story or something special you have done - for example, “I’ve done something you may not have done, which is…”.
Using everything that we've learned about LEGO Education SPIKE Prime competition programming we arrive at the final boss mission - how do we consistently reach a mission model at the other end of the field. Consistently. Every time. We use line following, motion sensor, counting of lines and border alignment. All the different concepts that we've looked at separately are now implemented together.
Here is Comet. It is a fast LEGO Mindstorms EV3 Car robot that looks like F1 Racing Car. We've especially designed it to be controlled with the remote control to make it extremelly easy to download the program and start playing with the robot. It also has the option to "press the pedal" (increase the speed) with just the remote control. Check it out.
Here is Turtle - a LEGO Mindstorms EV3 robot that is designed to look like a sea turtle (may look clumsy but it's not). It has two sensors - ultrasonic and gyro, capable of following its course and navigating through anything. It can even get "angry", if you annoy it too much.
What if the robot could make a mistake and still accomplish the mission? That is what we demonstrate with this tutorial - a few principles for error tolerance and self-correction. Even though we start the robot from a few different places, we manage to complete the mission with the same program every time. We use the LEGO Education SPIKE Prime robot, and we continue directly after the 10 out of 10 tutorial
In this self-paced, beginner-friendly online course, you and your child will learn how to create a rotating LED strip display—a glowing clock that seems to paint time in mid-air. And don’t worry if you’ve never soldered, wired a circuit, or touched an Arduino before. We guide you from the very first step all the way to powering on your finished display.
By the end of this journey, you’ll both have learned real hands-on skills—like how to solder, drill clean mounting holes, read resistor color codes, and work with common electronic components—all while building something that looks impressively “advanced” but is totally achievable for beginners.
Before you jump into the build videos, this first lesson gives you a clear picture of what you're creating—and what materials you’ll need to make it happen. We want you to have full confidence in what you’re investing in. There are no surprise expenses later: everything required is listed upfront, along with tips on where to buy each part.
This is a 10 out of 10 video tutorial for the FIRST LEGO League 2020 RePLAY robotics competition and the Treadmill mission. We build a robot with consistent behavior that is able to achieve the mission every time
The hall effect sensor can't detect a magnet, without there being one in the first place. While we can use glue or other ways of attaching a magnet to the clock face, we decided to use a second magnet on the other side of the face to hold the main one attached to it.
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
Make sure the connection between the clock arm and the clock's body is strong. Otherwise, it may sleep when you turn it on.
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
The 330 Ω resistor on the LED strip’s data pin acts like a tiny speed bump for the signal. It protects the LEDs by keeping the data signal from being too strong or too fast, which helps the strip work correctly and last longer.
In this video tutorial, we demonstrate an attachment that is activated when we reach the mission model. That means the attachment is not activated by a motor but by the movement of the robot. We accomplish the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model, where we have to move and bring cargo to the mission model and leave the cargo there.
The ground connection to the LED strip can be connected to any ground connection of this circuit. There is no danger of anything burning.
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.
Be careful with the power connection of the LED strip. If you connect it to the 9V battery line, it will fry the LED, and the strip will be ruined.
In this tutorial we demonstrate how a Flip Mission could be accomplished with a Flip Attachment. The robot attachment could be adapted to other flips in FIRST LEGO League/World Robotics Olympiad and other robotics competitions. The principle is the same. The tutorial uses Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
Measuring the center of mass of the arrow arm, in its unfinished form, will be inaccurate, but we can come closer to being accurate if we place as many of the components on it before making our guess.
We've recently received a number of question on how could the SUV box robot be charged. The answer is simple - you detach the back pane. The question and topic of detaching modules from a robot and attaching them again is really interesting and powerfull and yet not very often implemented in many robots.
A pull-down resistor keeps the Hall sensor’s signal at zero when no magnet is near. Without it, the sensor could get confused and give random on/off signals. It makes sure the circuit can clearly tell when a magnet is present or not.
As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it.
(we are releasing the video without explanations and will add the explanations later)
A Hall effect sensor is basically a tiny magnet detector. When a magnet comes near it, the sensor can “feel” the magnetic field and tell the circuit, usually by turning its output on or off. We can use it to detect things moving, like wheels spinning or doors opening.
Some microcontroller pins can act like tiny batteries (power) or tiny paths to ground. By setting a pin HIGH, it gives a little voltage to power something. By setting it LOW, it acts like ground, letting current flow back. This is useful for testing or powering small sensors,
In short: Hall sensors feel magnets, and digital pins can sometimes act like tiny power sources or grounds to help run them.
A clutch is a mechanical device that is used for engaging or disengaging power transmission. Now we will see how we can make such a device using LEGO.
