Lakshmi Life Sciences Senior Design Engineer Interview Questions, Process, and Tips

The selection of servo motor depends on the application requirements such as torque, speed, and precision.

• Determine the required torque and speed for the application

• Consider the required precision and accuracy

• Choose a motor with appropriate power and voltage ratings

• Consider the physical size and weight of the motor

• Evaluate the cost and availability of the motor

• Examples of servo motors include AC, DC, and brushless moto

Sensors are selected based on the type of measurement required. Common types include temperature, pressure, and proximity sensors.

• Consider the range and accuracy required for the measurement

• Choose a sensor that is compatible with the system being used

• Consider environmental factors such as temperature and humidity

• Examples include thermocouples, strain gauges, and ultrasonic sensors

Cylinders are used in various applications. Types include hydraulic, pneumatic, telescopic, and electro-mechanical.

• Hydraulic cylinders are used in heavy machinery, construction equipment, and industrial applications.

• Pneumatic cylinders are used in automation, robotics, and manufacturing.

• Telescopic cylinders are used in dump trucks, cranes, and other heavy-duty equipment.

• Electro-mechanical cylinders are used in precisio

A pick and place machine is a robotic system used to pick up components and place them onto a printed circuit board.

• Pick and place machines are commonly used in electronics manufacturing.

• They use a combination of vision systems and mechanical arms to accurately place components onto a PCB.

• The machines can handle a wide range of component sizes and shapes, from tiny surface-mount resistors to large connectors.

• Some pick ...read more

LVDT is a type of sensor used to measure linear displacement.

• LVDT stands for Linear Variable Differential Transformer.

• It consists of a primary coil, secondary coils, and a movable core.

• As the core moves, it induces a voltage in the secondary coils which is proportional to the displacement.

• LVDTs are commonly used in industrial and automotive applications for position sensing and control.

• I have used LVDTs in a previous p...read more

Yes, I have used indexer extensively in my previous projects.

• I have used indexer to access elements in arrays and lists.

• I have also used it to access properties and methods of objects.

• Indexer has helped me to write more concise and readable code.

• For example, I have used indexer to access specific elements in a dictionary object.
