Robot dishwasher could replace human workers


Robotic dishwasher capable of washing hundreds of dirty plates could replace human employees working gruelling shifts in restaurant kitchens

  • Dishcraft has developed robot that picks up plates and bowls by using magnets
  • Then scrapes off any leftover food with tool before rinsing with recycled water 
  • Dishes are then placed in a sanitiser before restaurant staff can use them again
  • Company has already raised $25million in venture funding since their launch

The worst part of working in any restaurant could soon be eliminated after a robot capable of washing the pots has been invented by a US-based start-up.   

Although there are more than half a million people employed as dishwashers in the US alone, the job is poorly paid, gruelling work and has a high-turnover rate.

But now Dishcraft, based in Silicon Valley, is hoping to tackle these issues with their automated dishwasher, reports CNBC.

The system currently works by using bowls and plates that have metal pieces attached to them, but the founders, Linda Pouliot and Paul Birkmeyer, hope to move on to other items in the future.

HOW DOES THE DISHWASHING ROBOT WORK? 

Dishcraft’s robot currently only works with plates and bowls the company develop themselves as it has metal pieces attached to the bottom and are much stronger than other dishware.

Workers place a stack of plates into a slot, where the robot picks up each one before hanging them above a food scraper which removes any leftovers before rinsing away the rest of the dirt using recycled water. The robot uses cameras and sensors to detect when the plate has been cleared. 

It then stacks the newly-cleaned dishes for a member of staff to take to a sanitiser to remove any germs before they can be used again. They used hours of time-motion studies in commercial settings to perfect their technique.

The firm has not developed their own sanitiser as they are already used as standard in many restaurants.  

Workers place a pile of dirty plates into a container that is monitored by the robot. Once it reaches a certain level, a light turns on to let workers know they should take them over to the dishwashing machine.

There, the robot picks up the plates with magnets and uses a rubber scraping tool to remove any food chunks, before rinsing off the rest with recycled water, using cameras and sensors to make sure the dish is actually clean. 

The robot then stacks the plates for another member of kitchen staff to take over to a sanitiser to remove any remaining germs.  

Entrepreneur Ms Pouliot decided to develop a dishwashing robot after realising there was a gap in the market thanks to the boom in eating out.

Explaining the decision in a blog, Ms Pouliot said: ‘As a serial robotics entrepreneur and someone who loves restaurants, I want to see them and the people within them thrive. 

‘For me, the challenges within the food service industry present some of the most exciting, impactful examples of how automation can help provide solutions for an industry.’

Ms Pouliot spent plenty of time washing up in restaurants herself to develop the robot, and even used ‘hundreds of hours of time-motion studies in commercial dishrooms’.

It seems the idea is already popular with restaurants, with Ms Pouliot adding: ‘Robots do not call off, robots don’t take breaks, and robots do not take vacation.’

Now the company make sure every person they hire has a stint dishwashing – as do all their investors.

So far, the firm has raised $25million in venture funding.

WILL YOUR JOB BE TAKEN BY A ROBOT?

A report in November 2017 suggested that physical jobs in predictable environments, including machine-operators and fast-food workers, are the most likely to be replaced by robots.

Management consultancy firm McKinsey, based in New York, focused on the amount of jobs that would be lost to automation, and what professions were most at risk.

The report said collecting and processing data are two other categories of activities that increasingly can be done better and faster with machines. 

This could displace large amounts of labour – for instance, in mortgages, paralegal work, accounting, and back-office transaction processing.

Conversely, jobs in unpredictable environments are least are risk.

The report added: ‘Occupations such as gardeners, plumbers, or providers of child- and eldercare – will also generally see less automation by 2030, because they are technically difficult to automate and often command relatively lower wages, which makes automation a less attractive business proposition.’
