Controlling the Fantastic Robot with Snap!

Controlling the Robot with Snap!

Communication from a web environment: Snap!

• As we have already seen in the previous unit, it is possible to communicate with the ED1 board through web requests (REST) ​​thanks to the fact that we can start a web server on it.

• The web browser is not the only one that can make this type of request, they can also be made from other applications.

• In this unit we will see how to control the robot from Snap!.

Sending commands from Snap!

• Snap! is a block programming environment very similar to Scratch but which allows you to create more complex projects, thanks to the fact that it includes more advanced instructions than this one.

• One of these instructions in the form of a block is the one that allows web requests to be made in the same way as if they were made through the browser bar.

• NOTE: for some reason it does not work in the Chrome browser and its derivatives, so it is recommended to use Firefox.
