Take BOB vibration analysis sensors. They sit quietly on pumps, fans, motors, learning the baseline behaviour of the equipment & when something changes, even slightly, they know.
Where my ears once picked up a faint change in pitch, BOB picks up micro‑vibrations.
Where my hands felt a bearing warming up, BOB detects the shift in frequency.
Where my intuition said “that doesn’t sound right,” BOB flags the deviation long before a failure.
It’s not replacing the engineer.
It’s extending the engineer’s senses into places we can’t always be.
