We are having an issue with our EV3 robot. Suddenly the robot is not running as per the program instructions. Our light sensor shows blue light when the Robot acts crazy. It is not detecting the distance correctly with the US sensor. When we test the US sensor , it seems to work fine.
We reset the brick... Turned off.. Deleted and reloaded the programs. Kids did practice runs for 2 to 3 hrs yesterday and everything was fine. Today when we started it acts very strange.
All sensors and ports seem to work when we look in the port view..
Has anyone experienced this issue ? Our tournament is on sat.
