If we wish to check if two sprites touch eachother or a specific sprite is touching something on the screen, the easiest thing to do would be to check the color! Now you will findout how to do this.

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.

In this course, you will learn how to program the game "Keep 'em clean". This is a game where the player controls a number of "people" on the screen using movements detected by a camera.

Detecting direction using the camera in Scratch is a very useful tool for controlling our sprite using movement. Now you will learn how it functions and how to use it!

Scratch is a very good platform for you to start learning to program. Here's how you can start and what you need to know for your initial orientation.

The goal of this lesson is for students to have fun with a new robot. 

Scores

Only one counts per stack

If an Upgrade (solar panels, roof garden, insulation) is Independent, and Supported only by a Stack which is at least partly in any Circle:

If there is a team-designed Structure clearly bigger than a Blue Building Unit, built only from your white LEGO bricks

Move the robot to the bring. Bring the flags up

The goal of this lesson is to introduce students to the setting for measuring the reflected light of the color sensor and to recall how to follow a line.

The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever. 

This video tutorial shows how the LEGO Mindstorms EV3 Rider Robot Motorcycle with Cart robot works. You can ride a friend with you.

This video tutorial shows how the LEGO Mindstorms EV3 Handlebar Chopper Motorcycle robot works. See how fast it is.
