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

Tips and common mistakes when connecting two beams together.

Notes on building the FiveMinuteBot

The most universal way to start your programs is from My Projects menu and we will cover details about that menu in the EV3 Brick.

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.

Construct two legs for both sides of the robot. The task for this video is to attach this two legs on both sides and to build a system of gears and axles that power those legs.

We will learn how to connect and disconnect LEGO cables and on which ports exactly to connect the motors.

This is how to use the display block to show images with the EV3 software.

Let's make a program that moves the robot forward and then backward.

This is a teacher's note about the math behind calculating gear ratios with for our lifting attachment. It math model we build in previous tutorials is not exactly correct and here is the explanation why.

A note why we give the challenge at the start of the lesson.

What is allowed and what is not when building without instructions.

Each palette contains programming blocks that share common purpose. We will cover most of them

There are some things to be careful about when your students work with the brick.

Let's make a competition - there is a pole that the robot must turn around and return home.

The task in this tutorial is to execute the program 10 times and to do it yourself. If you have your attachment then use it. If you have our attachment then use it. But execute the program 10 times and make sure that it works. 

Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot. 

Sometimes a good teacher needs a few tricks in his sleeve, so that he can surprise and entertain his students.

We will take a look at the EV3 motors and will go into details about them

Why we will never use seconds in our lessons.

Let us do a quick recap of the whole lifting mission and its solution

We will demonstrate with a robot what the acceleration is and the effects of high and low acceleration.

Every turn is a circular motion and we will review the three types of turns from this point of view.

What should you as a teacher know when the students are trying to achieve a program and robot attachment that could reproduce their behaviour 9 out of 10 times. 

If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"
