Structure an Investigation of Vibration at a Robot Base

Base vibration can originate in the support, nearby equipment or the robot’s own motion. Collect reproducible evidence first and have qualified personnel determine causes and remedies.

Fix the observation conditions

Record program, pose, load, speed setting and when vibration occurs. Avoid changing several conditions before comparison.

Review the support and connections

Have qualified personnel review the foundation, structural connections and fastener maintenance record under site shutdown and energy-isolation procedures.

Separate external inputs

When safe and operationally feasible, compare observations with neighboring equipment running and stopped. Record instruments, locations, method and duration.

Verify the remedy

After repair or structural adjustment, repeat measurements under the same conditions and review task quality against applicable requirements. Record remaining unexplained observations.

Applying the checklist: a hypothetical example

If vibration appears only while the arm moves in one direction, retain the program, load and observation point, then review neighboring equipment state and support maintenance. Replacing several components before retesting makes attribution difficult.
