It works when tethered but not wirelessly.
Have tries different pairings of radio chips in controller and brain but to no avail.
I have the most up to date VExos firmware on the brain/ controller and motors and on the computer.
Help we can’t drive the robot with a blue wire attached.
Please make sure the radios are inserted all the way down (picture attached). No blue logo should be showing, it helps if you push the red button on the brain while inserting, while on the Controller it helps if you remove the battery. If his fails, you can also swap the radio from the controller into the brain and the one from the brain into the controller.
If all this fails, please remove your radios and inspect the radio slot on the Controller & Brain. Make sure there are no exposed or smashed pins (picture attached).
