Plan for Catastrophic Sensor Failure

Any electronic component can fail. To ensure that your robot can still function during use even if such a failure does occur, your robot software should handle cases when communication with sensors such as the navX-sensor is disrupted.

An easy way to accomplish this is to use the “isConnected()” indication, and only use navX-sensor data to control your robot when this is true.

Additionally, displaying whether the robot software is connected to the navX-sensor circuit board on the driver “dashboard” can help the drivers quickly detect a connection problem.
