A fresh backup battery solved the problem for us.
Yes we've checked out backup battery, and it is fully charged.

It seems to also happen when the robot is perfectly idle.

So if you just let the robot sit there in operator mode (not disabled), and stare at it for 30-40 seconds, you might see the red radio light blip once or twice.
