The definition of a robot tends to be fairly fuzzy. If you look up the Websters definition (https://www.merriam-webster.com/dictionary/robot), and ignore the first definition about being in human form, you get:

> a device that automatically performs complicated, often repetitive tasks (as in an industrial assembly line)

Which basically hinges on "complicated". I suspect most people wouldn't count a dishwasher, washing machine, etc.
