Brunch with Sifted: Karakuri’s robot chef

Posted on Wednesday January 6, 2021 in In the press

Sifted has brunch with the Karakuri DK One food-making robot. What’s on the menu?

“Will it be serving you chips?” my husband asks when I tell him I am going to have brunch with a robot, a joke which, I point out, has not been funny since 1976. If ever. My Sifted colleagues, meanwhile, were wondering if we were going to have “Dalek bread”. But no, my brunch with the Karakuri DK One food-making robot arm, is in fact a bowl of muesli.

It’s a bowl of muesli and coconut yoghurt, with a helping of mixed berries on top, to be precise. Before it starts making the food, I can specify exactly how many grams I want of each thing. Then the robot arm — the first automated canteen for making meals —  whizzes around an enclosure the size of a small walk-in wardrobe taking the bowl to the different slots that will dispense the yoghurt, the muesli mix and the berries, before placing the bowl back in a small cubicle with a sliding door from which I can retrieve it.

Created by the three-year-old London-based startup Karakuri, the robot might be the closest we have got, so far, to the dream of a machine that makes you a tailored meal at the press of a few buttons. Like the Nutrimatic Drinks Dispenser in the Hitchhiker’s Guide to the Galaxy. Only hopefully more successful.

Though the winter dusk is deepening outside, the machine is making us brunch. Bowls and bowls of yoghurty muesli in different combinations that we can specify on a touch screen display that is connected to the machine.  Equally it could be making us bowls of dim sum, or poke, or salad — the components and ingredients inside the machine can be changed to suit the menu, hot or cold. But breakfast bowls are a simple thing for the prototype to practice on.

Karakuri unveiled the prototype machine in December, along with a £6.3m investment, led by firstminute capital, and supported by Hoxton Ventures, Taylor Brothers, Ocado Group and the UK’s government-backed Future Fund.

It is easy to get mesmerised by the moving robot arm, but this, points out Barney Wragg, Karakuri’s cofounder and CEO, is not the clever part of the system. The arm is a pretty standard piece of equipment that you can see in industrial production lines all over the world.  The clever part is an array of sensors, motors and AI behind the scenes.

“You can get robot arms to mix and serve food. But the really difficult part in the food industry is serving exactly the right portions, weighing and measuring and dispensing them,” says Wragg.

The machines made by rival robot-kitchen company Moley Robotics, for example,  he says, still needs a human to present it with all the ingredients of the meal in the right weights and quantities. This preparation and serving part is the bit that Karakuri wants to solve, in order to make robot catering a truly useful and scalable proposition.

Prototypes for the clever innards of the DK One are littered around Karakuri’s spacious office-and-workshop space in Hammersmith. There is a machine that squeezes yoghurt through a plastic tube in a peristaltic motion, exactly the way your gut moves food through. Wragg and his team have calibrated exactly how much yoghurt comes out at each squeeze, but also they have had to make sure that the parts of the machine that come into contact with the yoghurt — e.g the stainless steel pot in which it is stirred — are easy to remove and wash in a standard dishwasher. There is no point in building a labour-saving machine that takes hours to clean afterwards.

Another type of dispenser, for nuts and berries, works a little like the penny falls machines at an amusement arcade, gently shaking the contents so that they fall in precise quantities onto the serving bowl. There are sensors and scales that measure how much has already been dispensed and adjusts the shaking — more vigorous to start with and tapering off as the bowl fills — so that you get just the right amount.

In another corner, a robot arm that is being taught how to identify varying bits of grilled chicken, pick them up and place them in another dish. This is the mundane reality of AI. Newspaper headlines suggest it is going to take over the world. Right now it is being taught the work of a junior at a chicken shop.

An automated canteen could be a useful solution for a pandemic-scarred world where people are wary of human contact. The DK-One can serve somewhere between 60-100 bowls of food an hour to customers without the need for any customer-facing serving staff. Wragg says there is interest for the machine from large restaurant chains, big catering companies that serve hospitals, schools and work canteens, as well as from supermarkets.

The interest from supermarkets is possibly the most intriguing. Supermarkets are increasingly getting into the meal kit game — Morrison’s has operated its Eat Fresh meal kit business since 2018 and Waitrose had plans to buy Mindful Chef earlier this year. A meal-making machine would potentially make the meal-kit business more scalable, although Wragg has nothing specific to announce at the moment. Karakuri does have a relationship with Ocado, though,  which owns a minority stake in the startup.

At least as important as the touch-free food service is the portion control the machine can give. Restaurants work on razor-thin margins with protein being one of their biggest costs. Accidentally give every customer a sliver too much chicken and you can easily wipe out your profits, Wragg explains.

This was what originally led him to found Karakuri. “I had a couple of friends with restaurants and I was stunned at how little data there was in the trade. I saw a restaurant as something of a food manufacturing plant, and manufacturing is all about data and controls. There is typically nothing like that in a kitchen.”

Getting accurate data on ingredient usage  — more than any labour savings — is the biggest selling point for customers, says Wragg.

“It’s a known secret of the restaurant business that there is a problem with portioning and wastage.”

One potential customer, for example, wants a solution that would dole out bowls of biryani, a mix of rice and meat cooked together, so that there are at least four but no more than six pieces of meat in each portion. Doing that requires a mix of shaking machines to serve out the food and machine vision to spot the number of meat pieces.

Wragg — who has a varied background that includes both working at Arm, the microchip architecture designer and for many years at Andrew Lloyd Webber’s Really Useful Group —  founded the company at the end of 2017 and raised the first £7.2m seed round in April 2019. A further round in December has allowed them to complete work on the first prototype. Karakuri has now raised a total of £13.5m in funding.

The team has grown from 13 people this time last year, to nearly 30. Wragg expects the company to grow to around 50 people within the next two years.

Covid has had a mixed impact on the business. On the one hand, with the restaurant trade in severe distress, there are fewer customers willing to take a risk on something as experimental as a robot kitchen. On the other hand, it has made many bigger companies aware of the need to automate their businesses. Selling to bigger companies takes longer, but Wragg is hoping to have the first installations this year.

The first DK-One was supposed to be installed in the Ocado staff canteen as a test run, but with only a skeleton staff working physically at the offices because of Covid restrictions, it didn’t seem worth doing. Instead Sifted is getting this demonstration in the Karakuri workshop. Despite the machine producing a prodigious number of breakfast bowls, nobody is actually allowed to eat anything because it would violate various food safety regulations (and also, after seeing the yoghurt squeezing through the intestine-like tubes it has started to seem less appetising).

Instead we make do with black coffee from the modest capsule coffee machine in the corner of the office. That’s a catering machine that was invented some 36 years ago, initially for the professional, specialist market, but which has subsequently become ubiquitous and changed our coffee habits for good. Wragg can only hope that the Karakuri’s machines will have anything like the same impact.

“Heston Blumenthal wants robots to make your boring lunch” by Wired magazine

Posted on Monday February 24, 2020 in In the press

Story by published by Wired Magazine

The experimental chef has joined the board of Karakuri, a startup trying to automate the mass customisation of sandwiches and salads.

Heston Blumenthal flips through a small notebook. Inside are sketches and handwritten notes in beautiful calligraphy. On one page, he stops and indicates a mesh of thick scribbles that slowly resolves into the shape of a human skull. “Twenty-three degrees,” he says. “The angle that the spinal column enters the cranium is the same as the tilt of the earth on its axis.”

Blumenthal is one of Britain’s most famous chefs – his scientific, multi-sensory approach to cooking has won him critical acclaim, and a total of six Michelin stars for The Fat Duck and The Hind’s Head in the Berkshire town of Bray, and Dinner in London. His signature is misdirection: a tangerine is shaped from chicken liver, playing cards melt into chocolate.

But he has a wide range of interests: over the course of a couple of hours in his company, conversation veers from toxoplasmosis – an infection caused by a cat-borne parasite that can cause neurological problems in humans – to the politics of fear and irritating airline safety videos.

His latest venture involves robotics. In October 2019, Blumenthal joined the board of Karakuri, a London-based startup that wants to bring robot arms to restaurant kitchens. Co-founders Barney Wragg and Simon Watt worked together at chip-maker ARM, and in the music industry at Universal, and have backing from Brent Hoberman, the co-founder of and chair of Founders Forum. Karakuri has raised more than £7m in funding, and has 20 employees based in a former bicycle factory near Hammersmith, in west London.

In one demonstration, a robotic arm turns and twists to collect pick’n’mix sweets from automated dispensers. In another, a precise amount of yoghurt and granola are added to a cereal bowl. Eventually, Wragg says, the system will be able to enable mass customisation of food at restaurants, cafes and sandwich shops. Pret could be about to get predictive.

“People are much more sensitive about allergens and how their diet makes them feel,” says Wragg. “That’s putting huge pressure on the day-to-day food industry because it requires a lot more configuration.”

Karakuri’s technology is based around off-the-shelf robotic arms, which are normally found on factory assembly lines. Its key intellectual property will be in developing the infrastructure that goes around them, and building dispensers that can tackle the varying attributes of different foodstuffs: figuring out, for example, exactly how long you have to squeeze a container of mayonnaise to get precisely ten grams, or how the viscosity of honey changes depending on the temperature it’s stored at.

Food-delivery firm Ocado has made a £6m investment, and will soon be installing a robot arm in its test kitchen, where it could be used to prepare customised meals for home delivery. Right now though, Karakuri is focused on resolving a staffing problem at quick-service vendors – the kind of places where you might grab a sandwich on your lunch break. “Those restaurants, by their very nature, become very repetitive, very hard places to work,” says Wragg. “The move towards customisation actually makes those jobs more boring, and more difficult, and people are making a decision with their feet not to take those types of jobs.”

Chains and supermarkets have become experts at predicting what demand for a particular sandwich filling will be on a certain day, but they still get things wrong. “There’s a huge amount of wastage in the food chain,” says Wragg. Customisation will help improve efficiency, and Wragg says that robotics will help accelerate the adoption of big data by putting sensors on the frontline. “It’s about knowing where things are, what state they’re in, when they were grown,” says Wragg. “A lot of the good that data is going to do will be around sustainability.”

Eventually, Blumenthal hopes that robotics and artificial intelligence could have a wider impact. “We eat too much,” he says. “We do not appreciate food, and we throw food away. We need to change our relationship with food.”

Connected sensors and robotics could enable a future where you can track in real-time how your body and the microbes in your gut react to certain types of food, and where your meals could be automatically designed with your happiness in mind. Blumenthal is adamant that this shouldn’t be about prescribing people the foods they “should” be eating, though. “It’s not telling you to eat more spirulina, or not to drink or not to eat sugar. All it’s doing is mirroring and giving you the opportunity to know more about yourself.”

It’s not just sandwiches and salads. At Michelin-star level, Blumenthal says robotics will free up chefs to be more creative – to try things they couldn’t before because they would have been too difficult for humans to measure accurately or replicate consistently. “Unknowingly I created the most consistently precise, linearly driven restaurant system that exists in the world,” says Blumenthal. “Let’s get robots to do the measurement stuff for us much better than we can do, and let’s allow human beings to be human.”
