Front

What is the primary function of a sensor in a mechatronic system?

Back

To detect and convert physical phenomena into signals for processing.

Front

Name two types of sensors commonly used in robotics.

Back

Ultrasonic sensors, Infrared sensors

Front

What is an actuator and how does it differ from a sensor?

Back

An actuator performs actions, while a sensor detects and measures physical properties.

Front

Explain the role of a temperature sensor in a mechatronic system.

Back

The role of a temperature sensor is to measure temperature and provide data for control and monitoring in a mechatronic system.

Front

What type of sensor would you use to detect light intensity?

Back

Light-dependent resistor (LDR) or photodiode

Front

Describe how a servo motor functions as an actuator.

Back

A servo motor acts as an actuator by converting electrical signals into precise mechanical movement, using feedback to ensure accurate positioning.

Front

What is the purpose of a proximity sensor?

Back

To detect the presence or absence of an object nearby.

Front

List three examples of actuators used in industrial automation.

Back

Electric motors, pneumatic actuators, hydraulic actuators

Front

How do piezoelectric sensors work?

Back

Piezoelectric sensors generate an electric charge when mechanical stress is applied to certain materials.

Front

What is the difference between analog and digital sensors?

Back

Analog sensors provide continuous signals; digital sensors provide discrete values.
