Smile Robotics Makes an Autonomous Table Bussing Robot

Last year was a big one for restaurant server robots, those self-driving trays on wheels that shuttle food from the kitchen to your table and take your empty dishes back. Yes, the pandemic closed many restaurants in the U.S., but companies like Bear Robotics, Pudu Robotics, and Keenon Robotics all made news with their particular autonomous service bots.

All of those autonomous robots, however still require a human to manually transfer food to the table or pick up the dirty dishes and place them back on the robot. And as we live in a COVID world that values fewer human-to-human interactions, this is where Smile Robotics‘ robot could come in handy. The Japanese company has developed the ACUR-C, which can autonomously serve food and drinks or collect trays of dirty or empty dishes and carry them off.

You can check it out for yourself in this video Smile Robotics posted last year:

Autonomous Clear Up Robot (ACUR-C) [Smile Robotics]

That video only shows off the bussing aspect of the robot, and even that capability won’t set any speed records. A human would be able to clear those tables in a fraction of the time it takes the robot. But it’s a start, and as with all things robot, the technology is only going to improve.

The ACUR-C is fully self-driving robot. In other words, it doesn’t need ceiling or floor markers to “see” and navigate around a restaurant. It can carry multiple trays, and the “hands” of the robotic arm can be swapped out to either collect or serve items. We reached out to Smile Robotics to find out more and will update this post when we hear back.

It’s super easy to see the ACUR-C fitting into a restaurant like the Country Garden robot restaurant complex in Guangdong, China. That restaurant has robot servers and food descending from ceilings, but nothing (as far as we know) that will automatically bus the tables.

Smile Robotics, however, could be thinking a little closer to home. Japan has an aging population and is facing a resulting labor shortage. A robot table server + busser combo will undoubtedly find a lot of use there.

Video: Food Descends from the Ceiling in This Chinese Robot Restaurant

In June of this year, we wrote about a robot-run restaurant opening up in the Guangdong province of China. The Qianxi Robot Catering Group, a subsidiary of Country Garden, opened a restaurant complex featuring different robots that cooked and carried food.

One thing we didn’t know at the time was that meals would be dropped from the ceiling. At least, that appears to be what happens inside the restaurant based on a video we came across.

I should insert a few caveats here about this story. There is still a lot we don’t know yet about the video below, but it looks legit and is pretty remarkable, so we wanted to share it.

Yesterday Anthony James, CEO of Innovation and Growth at Trinity Consulting, posted a video on Linkedin showing how food travels around the inside of a robot restaurant in Guangdong, China. We don’t know who shot the video, and the restaurant in the video goes unnamed, but from the bright pink decor and pink robots, it appears to be the same restaurant we wrote about back in June.

The main reason we wanted to post this is because of the rail system that delivers orders. According to a follow up comment from James, guests place an order with one of the bright pink server robots that wheel about on the floor. The cooking robot prepares the meal, which then gets plated and sent out on a modified tray via an overhead rail system. When the meal reaches the ordering table, a tethered tray drops from the ceiling to just above the table where the customer takes the plate of food off the tray. The tray and tether then retract back up to the ceiling to go make another delivery.

You can watch the whole process here:

Interest around food robots and automation has accelerated this past year, thanks to the pandemic. Robots don’t get sick, and they also reduce the amount of human-to-human interaction involved in getting a meal from the kitchen to the customer. But robots are also fast workhorses that can operate around the clock. Country Garden’s robot restaurant in Guangdong can serve up a meal in as little as 20 seconds.

The bigger question for establishments such as this, however, is how much of an investment to make in dining room technologies. Here in the U.S., foot traffic into major QSR dining rooms is half of what it was at the beginning of the year. Would that investment be better spent automating drive-thrus and other forms of food to go? Perhaps the Chinese market will rebound differently.

If you’re a Spoon reader in Guangdong, China, do us a solid and visit the restaurant. Then leave us a comment and tell us what it’s like.

Bear Robotics and SoftBank Debut New Servi Restaurant Robot

Good-bye, Penny. Hello Servi.

Bear Robotics and SoftBank announced their new food service robot, dubbed Servi, at an event in Tokyo today. The new robot is actually a redesigned version of Bear’s Penny, an autonomous server robot that shuttles food and empty dishware between the front and back of house of a restaurant.

SoftBank is actually an investor in Bear Robotics, and led Bear’s $32 million Series A round that closed at the beginning of the year. The two companies have been working closely on Servi, and will focus initially on the Japanese market, where Bear has already lined up Denny’s as a customer.

Servi is coming to market at a time of heightened interest in automation in the restaurant industry. The COVID-19 pandemic has brought increased scrutiny over the amount and types of human-to-human interactions that happen when dining out. Robots like Servi can also work long hours without a break, won’t call in sick and don’t have to worry about awkward exchanges with customers over wearing their masks (e.g., taking a mask off to eat, putting it back on when ordering).

But Bear is not alone in the robot server space. With players like PuduTech and Keenon Robotics, server robots could quickly become a commodity, with restaurants just opting for the lowest cost option.

John Ha, Founder and CEO of Bear Robotics, told me by phone last week that Bear’s robots are different from the competition because of their full autonomous driving (no need for special tags to be placed on ceilings) and easier set up.

Ha was in South Korea at the time because Bear has an office in Seoul and that is where the company will be manufacturing Servi. This scaled up production, Ha said, will be a way Bear can fend off newer startups looking to break into the robot space. “People without mass production won’t be close anytime soon, because mass production is not a joke,” Ha said.

South Korea will also be among the first markets for Bear, with Ha saying that they have received a lot of inbound interest from restaurants there. In South Korea, Bear will go up against Woowa Brothers, which teamed up with LG and the Korea Institute for Robot Industry Advancement (KIRIA) to develop robot waiters as well.

As noted, the pandemic is accelerating the interest and adoption of food robots. So expect to be saying hello to a lot more robots like Servi in your not-too-distant dining future.

Pudu Tech Raised More than $15M as the Server Robot Space Heats Up

Pudu Technology, which makes autonomous server robots used in hospitality settings, announced yesterday a funding round of more than $15 million, according to VentureBeat.

The Shenzen, China-based Pudu makes a number of self-driving robots equipped with a rack of trays to shuttle food and drinks to and from customers inside a restaurant. Pudu introduced the BellaBot, which sports cat-like features and even makes a cute LED-face when you pet it, at this year’s CES.

Pudu’s funding comes at the right time, as the COVID-19 pandemic has forced restaurants and bars to reduce the amount of human contact during table service. Server robots like Pudu’s provide a way to reduce at least one point of human-to-human interaction while dining out.

But Pudu will also need the funding because the robot server space is getting increasingly crowded. In the VentureBeat story, Pudu claims has 2,000 customers including Sheraton and JD.com, across 20 countries. Rival Keenon Robotics, server bot company based in China, says that it has 6,000 robots in action and that it can produce 30,000 robots a year.

Over in Korea, Woowa Bros. partnered with consumer electronics giant LG to develop and expand its robot waiter program. In Spain, Macco Robotics launched its Dbot modular server robot. And here in the U.S., Bear Robotics, raised $32 million earlier this year for its Penny robot server.

All of this is to say that there are a lot of companies looking to bring robot servers to your restaurant. So much so, that as I wrote back in February, they could become a commodity:

It feels like restaurant server robots are on their way to becoming less of a novelty and will soon be a commodity. They all do the same thing — carry food. They are meant to do the grunt work so humans don’t have to. So the feature set will be the same: Take food to table > carry food without spilling > avoid humans and other obstacles along the way.

Sure, there are enhancements that can be made, or perhaps there’s a unique way to move food from the robot to the table. But there really isn’t much else for the robot to do. Server robots will become a commodity, and whichever company creates the cheapest robot that does a decent job will win.

Given the debate and debacle around re-opening restaurants here in the U.S., and restaurant workers test positive for COVID, we could see a rise in demand for restaurant robots. And it looks like there are plenty of companies ready if that demand comes.

Country Garden Opened a Massive Robot Restaurant Complex in China This Week

You may be debating whether or not you’re ready to go back into a restaurant. But what if that restaurant was operated entirely by robots? Would that make you more inclined to eat out?

Earlier this week, the Qianxi Robot Catering Group, a subsidiary of Country Garden, opened up a robot-powered restaurant complex in the city of Shunde in China’s Guangdong province.

The complex is 2,000 sq. meters (more than 21,000 sq. ft.) and serves Chinese, hot pot and fast food. The restaurant can serve 600 diners at once, offering 200 menu items that can be served up in as little as 20 seconds, according to the press announcement.

The complex has more than 20 robots developed in-house by Qianxi that cook up a variety of different styles including Chinese cuisine, clay pot rice and noodles. Though the press release doesn’t mention them specifically, from the accompanying photos, there is also a small army of pink server robots to bring dishes out to tables. No word on whether these were developed in-house as well, but they don’t look like the server robots make by PuduTech, Keenon or Bear Robotics.

Country Garden’s restaurant certainly isn’t the first to use robots. Spyce Kitchen in Boston uses robots to cook. Caliburger has Flippy grilling burgers. And Bear Robotics’ Penny server bot has been put to work shuttling food in restarants. But Country Garden seems to be among the first putting all of the front and back-of-house pieces together, and doing so at scale.

In addition to a having a bunch of robots, the Country Garden restaurant is also contactless, a factor increasingly important on our pandemic planet. As restaurants re-open here in the U.S., businesses and eater alike are grappling with restrictions like facemasks and socially distant tables. Having a full-on robot restaurant isn’t a guarantee to prevent the spread of COVID-19, but it does remove some human vectors from the equation.

It’s a question I’ve asked before, but what will make people more comfortable inside restaurants: the human touch while wearing a facemask and gloves, or the cold sterility of a robot?

Macco Robotics’ New “DBot” Modular Restaurant Robot Delivers Food and Disinfects

As restaurants around the world begin the process of re-opening, some of the (many) issues they will have to grapple with is keeping their establishments clean and reducing human-to-human contact. Macco Robotics wants to do both with its forthcoming Dbot.

The “D” in Dbot actually does double duty in this case, as it stands for “disinfect” and “delivery” (duh). The main part of the Dbot is a mobile base on wheels that uses lidar and computer vision to autonomously map out and navigate around the inside of a restaurant. Different modules can be attached to the top of the base, such as a sprayer, which mists out disinfectant, and a tray module for carrying food and drinks to tables.

This means a restaurant could spend its open hours shuttling food to customers without human servers (reducing a vector of transmission), and then turn into a sprayer at the end of the day. (Macco said that the robot can also be controlled manually, should a location require disinfecting in hard-to-reach places.)

It is this modularity, according to Macco Robotics’ CTO Kishhanth Renganathan, that will make Dbot stand out in what is becoming the quickly commoditized space of restaurant server robots. “It’s not just a delivery bot,” Renganathan said to me over the phone this week, “You are just buying one robot for two different applications.”

But will this flexibility be enough to entice cash-strapped restaurants devastated by the global pandemic and ensuing lockdowns? Bear Robotics’ Penny offers a swappable tray system, but there’s no reason it couldn’t offer some kind of sterilizer add-on. And if restaurants want a robot with a proven track record, they may look more towards Kennon Robotics in China, which has 6,000 robots already in use in restaurants and other hospitality venues.

If a restaurant wants to go with robots, what it chooses may just come down to price. Keenon’s robot can be leased for roughly $1,500 – $1,600 a month. Renganathan said that Macco will offer a lease as well, though pricing was not set yet.

In addition to swappable functions, another thing that sets the Dbot apart is how it fits in with Macco’s long-term vision. The company’s ultimate goal is to make a full-on, autonomous robotic restaurant experience. The Kime will one day leave its stationary kiosk to become a free-wheeling chef, and will hand off food to the Dbot, which will take it out to the tables. No human contact at all.

That vision is still off in the distance, though, and we need to get through this pandemic first. For restaurants planning on re-opening this summer, the Dbot will be available starting in July/August of this year.

Just in Time for a Contactless World, Keenon Robotics has 6,000 Food Server Robots Already in Action

As restaurants across the country start to reopen, one question we’ve been asking is, assuming people will even want to go back into restaurants, how will they want to be served? Will customers want their server to wear a mask or not wear a mask? Which is less off-putting?

Another third option that may become increasingly common is having a robot server in your restaurant. Autonomous robots can shuttle food and empty dishes to and from the kitchen, they don’t get fevers and they’ll never cough anywhere near you or your food.

One company making such robots is China’s Keenon Robotics, which launched its first server robots back in 2016. Keenon’s robots use both 3D mapping and specially coded stickers mounted on ceilings to navigate. A camera pointing up on the robot sees the sticker and determines its route. The robots also feature obstacle detection and automated stopping so they don’t bump into people. Robots can be leased for $1,500 – $1,600 a month.

Other players in the space include Bear Robotics and PuduTech, but what sets Keenon apart is scale. Of the 9,000 robots Keenon has operational around the world, 6,000 are already in the hotel and restaurant industry. Simi Wang, the Director of Global Sales at Keenon Robotics, told me by phone this week that the company can produce 30,000 robots this year.

The question now is, will that be too many robots… or too little?

Keenon certainly seems to be filling its pipeline. The company has partnerships with Burger King in China, the Haidilao hot pot restaurant chain, and recently entered into an agreement with Chinese delivery service Meituan Dianping to create a new contactless restaurant.

Will there be that same demand for server robots here in the U.S.? When I spoke with Bear Robotics’ CEO last month, he said that there was definitely more inbound interest in his robots. He attributed this increased interest to customers wanting more transparency into who has touched their food. But again, we’re at the very beginning stages of restaurants coming back online, so we don’t know how much people will actually care.

Pre-COVID, the labor crunch was a big factor for restaurants considering a robotic workforce. Casual and quick service restaurants in particular had huge churn rates. With so many people out of work, and so many fewer restaurants still operational, the economics of human labor won’t be as much of an issue. The question now will just be how much people trust other people to handle their food.

LG and Woowa Bros. to Develop Food Delivery and Serving Robots

South Korean companies LG and Woowa Brothers announced today that they will work together on developing robots that deliver food to tables at restaurants as well as to your front door (hat tip to The Investor).

The companies didn’t provide many specifics, just saying that there were synergies between the two and they looked forward to making a better world where robots and humans coexist.

The move isn’t surprising given that both companies have made numerous robotic moves in parallel up to this point. Just earlier this month South Korean restaurant chain CJ Foodville started deploying LG’s CLoi ServeBots at its locations to serve food and shuttle empty dishes.

For its part Woowa Brothers, which operates Baedal Minjok, South Korea’s largest food delivery operation, launched a robot rental program for restaurants in November of last year. And last summer, Woowa partnered with UCLA to develop cooking robots. Woowa was acquired by Delivery Hero for $4 billion last December, but prior to that, Woowa’s CEO had talked openly about how delivery robots should be multi-taskers and do things like take away trash and recycling.

The announcement comes amid the backdrop of the deadly coronavirus. Cases in South Korea have spiked, and as the disease becomes a global pandemic, robots are one measure being taken to reduce human-to-human contact. As we saw early in the virus’ spread, a quarantined hotel in China used robots to serve food to stranded travelers. In fact, robots could wind up being instrumental in the contactless method of food delivery, if proper sterilization procedures can be put into place.

LG certainly isn’t alone in its food robot endeavors. Sony has a big vision for cooking robots and partnered with Carnegie Mellon University to research them. Sony also recently launched a dedicated artificial intelligence unit that would work on “gastronomy.”

All of this is to say that with the intense focus from companies like LG, Woowa, Sony and more, the world of food delivery and restaurant robots is being primed to undergo massive advancements in the coming years.

Bear Robotics Raises $32M Series A. That’s a Lot of (Robot) Pennies

Bear Robotics, maker of the Penny restaurant server robot, announced today that it has raised a $32 million Series A round of funding. The round was led by Softbank with participation from LINE Ventures Corp., Lotte Group, Vela Partners, DSC, and Smilegate. Bear had previously raised $2 million from South Korea’s Woowa Bros.

Penny is an autonomous robot built to shuttle food from restaurant kitchens to tables, and carry back empty dishes. The company released the latest version of Penny last year, which we described at the time:

Penny 2.0 is more cylindrical in shape, and can sport up to three tiers of carrying surface. Not only can Penny carry more, a new swappable tray system means it can be configured to carry any combination of food, drinks or bus tub.

Bear Robotics founder John Ha got the idea for Penny after running his own restaurant and seeing the hard work that went into being a server. It’s a lot of walking and carrying for a job that doesn’t pay all that well. Ha’s aim is to let robots do the monotonous back and forth associated with food service so employees and owners can do more customer service.

Penny has yet to go into mass production or full scale deployment. The robot was being used at Ha’s restaurant for a time and at a South Korean Pizza Hut, but there hasn’t been any word on expansion from that pilot.

But Penny isn’t the only serverbot in town. At CES this month, China’s PuduTech showed off its BellaBot, which in addition to carrying dishes, also sported an LED feline face. If customers pet Bella, the cat purrs, though it also gets annoyed if customers keep it from its work.

Bear’s fundraise comes at a time when food robots are having a bit of a tough time. Zume, which used robots to help make pizzas, shuttered its pizza delivery service. Creator, the robot-centric hamburger joint, was left stranded by Softbank, which was going to invest. Cafe X shut down three of its San Francisco locations. And Miso Robotics lost both its CEO and COO last year, and instead of venture funding, is turning to equity crowdfunding to raise more capital.

With its new, bulked up warchest, Bear is better prepared to weather any automation storm, but now it has to deliver a whole bunch of meals.

PuduTech’s BellaBot Server Robot Will Make for a Feline Dining Experience

Chinese robot maker PuduTech is showing off its new restaurant robot, the BellaBot, at CES tomorrow. The autonomous bot features four trays for carrying food, avoidance capabilities and cat-like features.

We don’t mean cat-like in that it has a general antipathy towards humans and darts under sofa’s at the drop of a hat. Rather, BellaBot features a screen with a cat-like face and raised “ears” built into its design.

BellaBot is reminiscent of Bear Robotics’ (another animalized robot name) Penny. Both are made for the front of house at restaurants, sport trays for carrying food, and are dispatched to drive themselves to the customer’s table.

What makes BellaBot different is its feline inclinations. Rub the robot’s ears and its “face” will change to an appreciate expression much like a cat’s would. And, also much like a cat, if you pet it for too long, BellaBot “gets mad to remind you not to interrupt its job,” according to the press announcement.

You can see it in action in this video from PuduTech:

Delivery Robot BellaBot - a new member of PuduTech.

At CES BellaBot will also be joined by HolaBot, another new robot from PuduTech. HolaBot is basically a busser robot, returning dirty dishes back to the kitchen for cleaning. HolaBot has a 120L enclosed cabin with three levels of trays each able to hold 20kg. HolaBot can carry 120 small plates, 39 large plates and 33 bowls in a single trip.

PuduTech’s robots are being made for restaurants in China that don’t have enough waiters. The BellaBot is actually the next generation of PuduTech’s similar PuduBot, which doesn’t have the feline fun. PuduBot is already in use in more than 2,000 restaurants around the world, according to the company.

Robots like the BellaBot and Penny are arriving at a time when more of a restaurant’s business is moving towards delivery and off-premises. There will always be restaurants to dine in, but as delivery options become more available and more popular, how much automation will the restaurant industry actually need? Robo-cats, however, will probably always have a market.
