This page shows all the robotics tutorials listed without specific grouping. Each tutorial is short, on specific topic, has a video. Some tutorials are in a few languages. Tutorials are structured in sequence in Courses or are grouped together in Tags and Categories
Most of the published video tutorials that you could learn from.
Why is it very important to keep in touch with your existing clients during a crisis.
How to talk to them.
What emails to send.
When we work with any sort of program, we need to save our files regularly to our computers. Afterwards, if we want to work on an old file, we need to load it from the computer.
Now we will learn how to do that in Scratch.

Note: You can only get Flag points if you get Bridge points.
Note: Rule 31 allowance: It is okay and expected for Robots to collide while trying to earn Flag points.Note
Note: When clearly only one Robot is holding a Flag raised, only that Robot scores for that Flag

Third wheel experiments, changes in the robot, students could choose the task all by themselves. Make sure you have a lot of fun and students complete their tasks. Here is what you should know when conducting this class.
This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever.
Here is Lintu. It is a marvelous LEGO Mindstorms EV3 Animal robot that looks like Kiwi, the famous New Zealand bird. It is quite rare to see a Kiwi bird in person. But fear not, we've prepare a robot that looks almost exactly like the original.
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.
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.
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)
The after season review continues. No. We are not publishing a single solution for the next season before it is over, but let's learn from the previous season. The current tutorial is about three missions at once on a single run with the robot. Most FIRST LEGO League teams try to accomplish one-two missions on a single run out of the base, and three is really what makes the difference
DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways.
You could use the LEGO Steel Balls as a third wheel on the robot. It is a caster wheel. But this is steel and as we know from basic existence on this planet, where there is steel there is also rust. The steel ball could get quite rusty and this could have an influence on the behaviour of the robot
Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.
The LEGO Mindstorms EV3 set comes with two LARGE motors. But even though these motors look almost the same they are not quite the same. There are always some differences in their behaviour. If you have more than two motors, because you bought them or you won them somewhere at a competition, it is worth doing an experiment to find which pair of motors works best.
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.
The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts.
The robot can move with different speed by applying different power to the motors. It will most of the time make smaller deviations when it moves slower. But you can't just move with a power of 10 all the time. This is a way too slow especially for competitions like FIRST LEGO League or World Robot Olympiad. In this video tutorial I would like to discuss the balance between motor power and robot movement error, how does the battery influence the power of the robot and to conduct an EV3-G experiment that will record the values of the Gyro Sensor along with the current power.
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.
This video tutorial contains a detailed description on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called Emergency Walk, which I think is one of the most interesting missions ever in FIRST LEGO League competitions. Join me in for a short explanation.
This is the first run of Team "Nightbeast", with which they solve M01 and M02 from FIRST LEGO League 2019 Into Orbit:
This is the fifth and the last run of the Nightbeast team. Robot goes out of the base, do missions:
and stays on the field. It's a common practice for the competitors to left the robot on the field after the last run. This allows them to do some important points at the end of the match.
In the second run Nightbeast team solves different tasks from two missions - M05 Extraction and M06 Space Station Modules:
In the third run Nightbeast team solves Mission 04 - Crater Crossing and partly Mission 03 - 3D printing and Mission 014 Meteoroid Deflection:
