Why Should I Update?

There are several reasons why you should update your VEX IQ Brain’s firmware with the latest VEXos, some of these include:

  • Each update of VEXcode IQ will require the latest version of the VEXos firmware installed on the brain before user programs can be downloaded.
  • VEXos updates will include fixes for known bugs and add the software which is needed to operate any new devices introduced into the VEX IQ line.
  • Updates allow for advanced programming features.
  • The best way to ensure that your VEX IQ system is functioning properly is to keep the Robot's software up to date.
