What types of motors do you use in your industrial robot designs?

While there are a number of different motors, including different brands and models, the interviewer is expecting a more general answer. You can respond by listing the different types of motors used in robotics, and then discussing some of the sub-types. It may help if you provide an example or two of motors you have used in previous jobs and discuss why you elected to use these. As with any operational question, be prepared for follow-up questions from the interviewer.

"Robotics systems employ many different subsystems. These include electronic, mechanical, pneumatic, and computer processors. Most of the motors used in a robotic device are electromechanical. There are a variety of different motors a designer can choose from. These include servos, stepper motors, arm-adapted motors, and devices employing belt drives. The type of motor you select depends on the action or movement the robot is designed to accomplish."
