Why Industrial Robots Fail (And How to Prevent It)
Industrial robots most often fail due to overlooked issues like cable fatigue, improper programming, and environmental factors—not the catastrophic component failures most teams expect.
Why This Happens in Real Plants
-
Repetitive Motion: Constant twisting and bending wears out cables and hoses.
-
Overheating: Poor ventilation or clogged filters in the controller cabinet cause thermal shutdowns.
-
Programming Errors: Incorrect payload data, singularity points, or joint over-speed conditions stress the robot's mechanics.
-
Environmental Factors: Dust, weld slag, or moisture ingress damages seals and electrical components.
What Most People Get Wrong
Most maintenance teams focus on reactive repairs, replacing a component after a failure without investigating the underlying cause. This leads to a cycle of repeat failures, unnecessary downtime, and inflated maintenance budgets.
What Actually Works
- Proactive Cable Management: Use high-flex cabling and properly routed dress packs.
- Regular PMs: Clean controller filters, inspect for wear, and back up robot programs.
- Program Optimization: Ensure accurate payload data is set and avoid singularity zones.
- Environmental Protection: Use protective covers or IP-rated robots in harsh environments.
When to Involve a Partner
If robot failures continue after addressing basic maintenance, it's time for an expert review. Persistent issues often point to problems with the initial application design, system integration, or program structure that require specialized robotics expertise.
