When the interviewer asks you this question, they expect you to respond with very detailed descriptions about the robust used in industrial settings. They also anticipate that you'll include the technologies used to create these devices and a description of their purpose in your answer. A good way to frame your response is to list each type of industrial robot you are familiar with, providing a brief description of its function and some of the features that make it unique.

"Industrial robots are devices or machines used to manufacture a product or perform a specific function in the industry. Since this is the oldest and most developed type of robot, they have become standardized and well-defined. Some of the major types of industrial robots include:

- Articulated robots, which have one or more rotatory joints, are used to manipulate or move objects.
- Cartesian robots have three linear joints, each of which moves in either an X, Y, or Z-axis. They may also have a joint that can rotate up to 360 degrees.
- Cylindrical robots have a joint that can either rotate or move linearly.
- Delta robots are shaped like a spider with parallel arms connected to universal joints.
- Polar robots can consist of a rotatory base and a vertical extension usually consisting of a single arm.
- Selective Compliance Assembly Robot Arm, or Sacra robot. These may move linearly in the X and Y directions around the Z-axis."
