A robot may be delivering your fresh towels at hotels from now on.

An autonomous robot named Relay is currently bringing items to guests at some hotels in California. People who call down to the front desk for an item, like a toothbrush or towel, will be greeted by the adorable robot that is capable of moving autonomously throughout the hotel.

The little guy is currently being used at six hotels in California, where it has completed more than 13,000 deliveries, according to the Savioke website. Those six hotels fall under four separate brands: Starwood Hotels and Resorts Worldwide, Wyndham Worldwide, InterContinental Hotels Group, and Marriott International.

Savioke raised $15 million in Series A funding at the end of 2015 to expand the Relay fleet.

According to the Los Angeles Times, there are 12 of the robots being used in California currently, with plans to expand that number and potentially include one near Los Angeles International Airport.

Relay is three feet tall and uses WiFi and 3D cameras to autonomously make its trips. The robot has made so many deliveries it adds up to 70 marathons worth of trips. Relay is also personable in its own way — making sounds reminiscent of R2-D2 when doing deliveries.

And it's pretty easy to use. When a guest calls the front desk for an item (Savioke says the most popular delivery is toothpaste), the staff member simply puts the item in Relay's top compartment. After entering the room number into Relay's tablet head, Relay will head up to the room on its own and call the guest's phone when it's at the door.

Savioke put a lot of effort into Relay's design so it wouldn't frighten guests or make them feel uncomfortable, Adrian Canoso, design lead at Savioke, said in a video. The base was created to make the robot seem stable and planted, and an arc is included under the robot's tablet so it appears to be smiling.

But using robots in hotels in nothing new — a Japanese hotel uses robots to check guests in and bring their luggage to their rooms.
