What are the basic components used to engineer a robot?
This question may seem similar to the one you were asked earlier in the interview. Interviewers often ask similar questions about the same topic for several reasons. The first is because they have a specific interest in this topic and want to explore it in detail. Another reason is that this enables them to correlate your answers. This helps them determine if you are answering honestly and consistently rather than creating answers on the fly. Interviewers prefer candidates were truthful, even if they don't know the answer to a question.
When you recognize that the interviewer is asking a question you already answered, try to be patient and understand the reason behind this. Rather than state that you already provided this information, simply answer that question the same way you did the previous one. This will demonstrate your consistency and your knowledge of the topic. It will also convince the interviewer that your answers are honest to the best of your knowledge.
"While there are many different types of robots, they all have similar components. The main components in virtually every type of robot include some type of power supply, actuators that convert power into movement, motors to drive the movement, sensors that provide the robot input they can respond to, controllers which manage the components' functions, and a framework to hold all of the components together. Robot developers can specify these systems to create robots with a specific function and can perform the task they are developed for."
