## Summary

A user on r/robotics asked which components of collaborative robots (cobots)—motors, actuators, gears, or electronic parts—fail due to wear when running 18 hours a day on the same task for 2-3 years. The Chinese-made cobots they encountered had only run 5-10K hours, most users had not yet encountered failures, and some UR users said the equipment itself had no problems.
