Using serial comms from the browser is really important in educational robotics programs. Both First and Vex platforms support it. Kids can access the web based coding environment on their chromebooks, and send code to the robots with a usb cable.

We recently restarted our middle school robotics club. The school had a lot of old Vex EDR equipment for which the coding software is windows only so that really limited what we could do related to coding. Glad to see Firefox getting up to speed on this.
