If you stay at a hotel during the pandemic, a robot may deliver wine to your door or clean your room

Picture this: You use your hotel's app on your phone to ask for extra towels. Your phone rings and you hear that your delivery is ready. Open the door and you find a 3-foot-tall bellhop has arrived with your linens. Were you picturing a robot? Because at certain Hilton and Marriott hotels across California, a robot is what you'd find.
