Connecting with Web-based VEXcode 123 - Chromebook

It takes just a few steps to connect a 123 Robot to Web-based VEXcode 123 on Chromebook.

Turn on the 123 Robot by pushing the 123 Robot along a surface to “wake” it.


Launch web-based VEXcode 123 by navigating to (View the Setting Up VEXcode 123 VEX Library article for browser and device requirements.)

Open VEXcode 123 and select the Robot icon in the Toolbar.


Select ‘Connect.’


Select the name of the 123 Robot you want to pair, from the list of available Robots.


Select the ‘Pair’ button, once you have chosen your Robot.


The Robot icon will turn orange and a ‘Connecting to:’ message will appear while the Robot is connecting.


Once the 123 Robot is connected the Robot icon will turn green. The message in the window will say ‘Connected to:’ and list the name of the Robot that is connected to Web-based VEXcode 123.


Underneath the 'Connected to:' message, there is an icon that displays the battery level of the 123 Robot.

The level in the battery will appear as one of three colors:


Red for a low battery level
