I would build a robot that would assist around the house picking up , notifying me of event going on in the house when I am away, and interacting with other hardware in the house through IoT automation. This would bring a whole new meaning to smart home and enable true home automation that is not just for gadget geek, but open to the masses. Traditionally, smart home hub and devices tend to intimidate the average consumer but with robots you can place a lively face and voice on automation which will ultimately help customers embrace and accept this groundbreaking technology.
