These cute robots could deliver your next coffee
By Rebecca Cairns, CNN
Trundling around the hallways of Hong Kong’s Cyberport innovation hub, the little Rice Robot is on a mission.
The stocky white cuboid resembles Star Wars’ R2D2 robot in its build, but has the wide-eyed expression of Pixar’s WALL-E. It’s delivering drinks to patrons of the HFT Life cafe in a compartment in its “head” which is unlocked by the customer using a PIN code sent to their phone.
While Rice’s operations at the cafe are limited to distributing drinks, the compact robot is already providing a range of services at venues in Hong Kong and Japan. Rice is deployed as a bellhop at Hong Kong’s Dorsett Wanchai hotel, providing room service to guests. In Tokyo, it delivers snacks to employees at SoftBank Group’s headquarters from the building’s 7-11 convenience store. Earlier this year, Rice even made its TV debut on Cantonese drama series Communion, delivering coffee to a cast member.
Rice is part of a new generation of smart robots, capable of navigating complex and busy environments, including elevators. Equipped with light sensors, depth cameras and ultrasound sensors to avoid obstacles, Rice can maneuver freely around multi-story hotels and shopping centers, says Viktor Lee, founder and CEO of Rice Robotics.
Describing Rice as “your friendly neighborhood robot,” Lee hopes it can help the hospitality sector combat labor shortages as the population ages, while appealing to the post-pandemic demand for heightened hygiene protocols.
“Even after COVID, people are paying a lot of attention to contact,” says Lee. He believes “this type of delivery robot will see steady growth in next five and 10 years.”
Pandemic robot boom
With a background in logistics, Lee founded Rice Robotics in 2019 to solve the challenge of “last-mile delivery.”
Supported by the Cyberport Incubation Programme, Lee and his team developed Rice, the first of its three robots. Designed for delivering goods, it can be used in healthcare, retail, logistics and hospitality.
The pandemic created new demand for service robots, with the market growing 12% in 2020 according to the International Federation of Robotics. This opened up a new role for Rice: quarantine hotel butler. In Hong Kong, strict regulations have seen inbound travelers quarantined for up to three weeks, and hotels have had to come up with new ways to minimize human contact and prevent cross-contamination.
The Dorsett Wanchai hotel started using Rice robots in June 2021. “It’s a great way to serve our guests and to maintain our service standards while adhering to social distancing and anti-pandemic measures,” says general manager Anita Chan, adding that feedback from guests has been positive: “With its cute appearance, Rice Robot is especially loved by the kids.”
Lee says that during the pandemic, clients began asking about cleaning robots. His team responded by developing a second robot, called Jasmine, in just eight weeks. Replacing Rice’s delivery compartment with a tank of sanitizing solution, Jasmine has two spray nozzles on her head to disperse disinfectant.
Lee created a new personality for Jasmine — which has already been deployed in malls, conference centers and airports — by giving her cartoon eyebrows that furrow in a serious expression. “She has to go out and sanitize the whole place, and she doesn’t want anyone to get in her way,” says Lee.
The team’s third product, Portal, is a taller robot with a touch screen, two-way intercom and streaming cameras for patrolling public areas. As well as making deliveries, Portal can guide visitors in venues such as shopping malls, conference centers and hospitals.
Hospitable robots
While industrial robots are commonplace in the automotive, manufacturing and electronics sectors, until recently most service robots in hospitality were used for novelty purposes.
But the pandemic has changed that, says Kaye Chon, dean of the School of Hotel and Tourism Management at the Hong Kong Polytechnic University.
In response to travel and social restrictions, “there was an exodus of employees in our industry,” says Chon. Combined with concerns about hygiene and a growing acceptance of smart tech from younger customers, Chon sees robotics as the next step in the hospitality industry’s “digital transformation.”
However, the technology still has to overcome some hurdles to achieve the same efficiency as industrial robots. Costs are still high for this technology — Rice Robotics’ products cost from $9,000 per unit — and malls, hotels, and restaurants need to be adapted to be robot-friendly, says Chon.
Staff also need to know how to program the robots, a skill set that is lacking in the industry. To remedy this, Chon helped devise a new “smart tourism” curriculum covering AI, robotics, and big data, but says it will take time for current students to enter the workforce. “This is the way our industry is evolving,” he adds.
Rice Robotics has created a fleet management app for users, and helps clients make infrastructural changes, such as programming the robots and elevator systems to communicate with each other. The startup also offers its robots on a monthly subscription service, starting at $800 per unit, which includes technical and on-site support.
And while robots can help to minimize contact between people, they still need to be sanitized by staff between uses, says Chon.
Chon sees great opportunity for robots to perform simple, repetitive tasks in budget and mid-range hotels — but the technology is still a long way from replicating the “small, personal touches” that high-end luxury properties sell themselves on, he adds.
Rapid expansion
Rice Robotics isn’t the only player in the service robot space. Danish company UVD Robots provides robotic butlers to Yotel’s hotel in Boston. US-based Relay Robotics (formerly Savioke) has been building delivery bots for hotels since 2013, and Richtech Robotics’ Matradee robot assists human waitstaff as an autonomous serving tray.
However, Rice’s cute facial features add to its appeal — an intentional part of the design, says Lee. Studies have found that human-like features increase affinity towards robots, making Rice’s aesthetic a key part of its effectiveness in the hospitality sector for brands hoping to make a good impression on customers.
Rice Robotics has expanded rapidly during the pandemic, from an three-person team in 2019 to 26. Now based in the Hong Kong Science and Technology Park, the company opened an office in Japan in 2021 to help manage its growing client base there. With a rapidly aging population, Lee says robots are essential to support Japan’s retail and hospitality sectors.
Beyond hospitality, Lee sees robots becoming more common in our homes, too. In a recent project with Japan’s postal service, several Rice units were deployed in a high-rise building to help deliver parcels and mail to residents’ doors.
“Robots are not taking people’s jobs, but rather trying to help keep society moving,” says Lee, adding: “Robots are the future.”
