Why predictive maintenance matters more as factories add robots
As factories deploy more robots, predictive maintenance uses equipment data such as vibration, temperature, motor current, torque, and controller alarms to identify early signs of wear in joints, reducers, motors, and controllers, so maintenance decisions are based on actual condition rather than a fixed schedule. IFR data shows that about 5 million industrial robots were in operation worldwide in 2025, up 11% year over year, and an unexpected failure of a single robot could affect an entire work cell and production line. Earlier warnings can reduce unplanned downtime, improve spare-parts planning, and make maintenance windows more controllable.
