As factories fill with robots, predicting breakdowns becomes the new must-have skill.

Factories worldwide are increasingly relying on robots, with about 5 million industrial robots now in operation according to the International Federation of Robotics. As robots handle more critical and precise manufacturing tasks, their unplanned downtime becomes exponentially more expensive, potentially disrupting entire production lines and causing cascading delays throughout a plant.

Traditional scheduled maintenance can't catch subtle, developing issues inside a robot's joints, motors, or controllers while it's still running. This article explains how predictive maintenance, which uses real-time robot data and analytics to spot early warning signs of wear and failure, is becoming essential to maximize uptime and productivity in automated factories. The core takeaway is that as manufacturing becomes more robotic, maintenance must become more predictive to keep the lines running.
