It sounds like science fiction, but more and more fast food companies are offering innovative food delivery methods, including drones, robots and chatbots.
KeyBanc Capital Markets analyst Chris O'Cull said in a research note Friday that delivery is the fastest growing segment in the fast food industry.
O'Cull said, using KeyBanc's restaurant delivery tracker, that certain fast-food restaurants are seeing "the largest quarter-on-quarter net adds" for the first quarter due to their delivery options.
Here's a look at some of the biggest companies leading the charge.
The pizza giant prides itself on its delivery innovations. In addition to Ford cars, you can order a pizza using Google (GOOGL - Get Report) Home, Facebook (FB - Get Report) Messenger, Amazon Echo and even by tweeting a pizza emoji on Twitter (TWTR - Get Report) .
Both Domino's and archrival Pizza Hut are experimenting with robots. Domino's is working on robot delivery, while Pizza Hut, owned by Yum! Brands (YUM - Get Report) , unveiled a high-tech concept restaurant in China including a robot host.
Another Yum! Brands company, KFC, teamed up with Chinese tech company Baidu (BIDU - Get Report) for a robot-staffed restaurant in Beijing where facial recognition software scans customers and recommends food orders.
In November, Domino's also completed the first commercial drone delivery of food in Australia. Domino's drone partner, Flirtey, has also completed drone deliveries from 7-Eleven stores in Nevada.
Chicken wing chain Wingstop's (WING - Get Report) delivery options include deals of the week and group ordering when you sign up for an account. The service is offered through its partnership with online food delivery company DoorDash.com.
KeyBanc's O'Cull highlighted Wingstop as one of the fast-food companies likely to see record quarter-on-quarter sales gains in the first quarter due to delivery.
Red Robin (RRGB - Get Report) , the chain of fast casual restaurants known for their gourmet burgers, began offering delivery services at 70 restaurants across the U.S. in December through a partnership with DoorDash.
KeyBanc sees record sales for the company in the first quarter, too, since teaming up with DoorDash.
This year, Buffalo Wild Wings (BWLD) began launching delivery services at 100 restaurants across the U.S. Customers can order from the chicken wing king through DoorDash or its competitor GrubHub (GRUB - Get Report) .
Buffalo Wild Wings is another company expected to see a sales boost in the first quarter due to its delivery service, according to KeyBanc.
KeyBanc's O'Cull said Jack in the Box is set to see its sales soar in the first quarter after partnering with DoorDash.
