Our approach

We find the problem at its source

Robot diagnosis and repair is the systematic inspection of mechanical, electrical and software systems to find the root cause of a fault rather than its symptoms, followed by a planned repair.

Abnormal noise, vibration, oil leaks, poor performance or unexpected movements in your robot systems can cause serious losses in production.

Woirtech analyzes the source of the fault through its diagnostic process and plans the repair steps needed to get your robot running safely, stably and efficiently again. Early diagnosis prevents a minor issue from turning into a major failure that requires a gearbox or motor replacement.

Warning signs

Fault symptoms that need attention

If your robot shows any of the following symptoms, early diagnosis can prevent bigger failures and production stoppages.

  • Abnormal noise
  • Abnormal vibration
  • Low oil level
  • Oil leakage
  • Jerky motion
  • Abnormal movement on any axis
  • Loss of repeatability
  • Unexpected stops and alarms
Repair process

Controlled repair in five steps

We accurately analyze the problem in your robot systems and carry out the required work in a planned, controlled way.

  1. Step 1: Initial assessment

    Fault symptoms, alarm history and operating conditions are analyzed.

  2. Step 2: Technical diagnosis

    Mechanical, electrical and software checks are carried out.

  3. Step 3: Intervention plan

    The required repairs, part replacements or adjustments are defined.

  4. Step 4: Repair

    Our expert team carries out the required technical work.

  5. Step 5: Testing and verification

    The system is run, and safe performance and accuracy are verified.

Questions

Frequently asked questions about robot faults

Contact us

My robot is making an abnormal noise. Can I keep running it?
We do not recommend it, because abnormal noise is usually a sign of gearbox or bearing wear and continued operation can make the damage worse. We recommend having it diagnosed as soon as possible.

What causes loss of repeatability?
Loss of repeatability is caused by mechanical backlash, lost calibration, encoder problems or deformation after a collision, all of which reduce the robot's ability to return to the same point. We identify the cause during diagnosis and fix it through calibration or part replacement.

Is the robot's accuracy checked after repair?
Yes. After every repair we perform a test run, verify accuracy and safety functions, and report the results.
