Some Exception Handling Methods
Q: What if your system randomly misses data from a sensor? (continued)
A: If data is too stale and the system cannot function properly without the
new data, switch to a degraded mode of operation
– In a navigation system, this might be a backup navigation mode
that operates on minimal inputs, separate from those that have
failed
– In a space explorer robot system, this might be a zero-velocity state
where the robot waits for communication of a set of new
commands
