Mechatronics Engineering — Diploma Interview Q&A Q1 What is Mechatronics Engineering? Answer Mechatronics is an interdisciplinary field that combines mechanical engineering, electrical engineering, electronics, control systems and computer/software technology. Its main objective is to develop intelligent and automated machines and systems. Q2 Why is Mechatronics called an interdisciplinary engineering field? Answer A mechatronic system normally requires multiple engineering disciplines to work together. For example, an automated machine may use mechanical components for movement, sensors for measurement, a PLC for control, motors for actuation and sof...

How would you troubleshoot it? Answer I would first observe the sequence and identify whether the issue is mechanical, electrical, sensor-related, pneumatic, or software-related. Then I would check alarms, I/O signals, wiring, sensors, actuators, and PLC/robot logic to isolate the root cause. Q2 A proximity sensor is not detecting a component. What would you check? Answer I would check sensor alignment, sensing distance, target material, power supply, wiring, and sensor LED indication. I would also verify the PLC input status to determine whether the problem is with the sensor or the control system. Q3 A p...
