The Ultrasonic distance sensor can help the robot avoid obstacles.

A quarter of a rotation is a very short distance and the result is that the robot moves only a little.

That turn is very different from the quarter-turn of the motor.

If I return to one of our previous programs for pivot turn, let me just start it so that you can see it on the camera.

We move forward and as you see we are not turning to exactly right.

We are turning slightly to the right but we must turn forward more.

Program The Lego Mindstorms Ev3 Software Ill Create

In the software Ill create a new project Ill zoom this project and its simple we need to make the robot turn to 90 degrees - turn right.

So, Ill just take the large block like this Here Ill click on degrees and here Ill set 90 degrees.

Why And thats a very common mistake in most of the classes and like 80 or 90 of all the students are doing this mistake.

The reason is that weve programmed the wheel to turn to 90 degrees like this.

And the wheel turning to 90 degrees does not mean that the whole robot will turn to 90 degrees.

Its just the wheel turning to 90 degrees.

Again. So, turning the wheel to 90 degrees does not mean turning the whole robot to 90 degrees.

I dont know the correct value and this will make the whole robot turn to 90 degrees.

Today we will see what other options our robots have for turning.

Students work with new concepts like loop, degrees and medium motor.

Robots can now do two different actions at the same time - while solving missions on a field, the third motor clears detected obstacles.

You will need to find which support wheel resists the least when turning.

It will be too expensive to send a mechanic to the moon to help him.

We will have to determine which wheels would get stuck easily in a small hole and which wheel can the robot pull out.

Having in mind teachers busy schedule, we have design two different schedules and added an option to design one just for you.
