Do we need robot lawn mowers?

  • July 30, 2021

On a recent visit to the German town of Rheinsberg, my husband and I stayed in a charming bungalow with a beautiful garden whose central feature was a wooden swing which hung from a large, old tree.

The young man who greeted us on arrival was solicitous, guiding us through a well-stocked country-style kitchen, a cozy living room lined with books and a map detailing the main attractions of the town.

Just as he was preparing to leave us to settle, he issued an apology. “I’m sorry about the grass,” he said.  “We’ve been having some issues with our mower.”

Not that we would have noticed ourselves, but the lawn did indeed look a little unconventional, with streaks of wild growth coexisting alongside impeccably trimmed sections.

He motioned in the direction of a hedge, where a small, disc-shaped machine was parked. “It’s not performing as it should,” he said.

Nature’s new soundtracks

Over the course of our three-day stay, the robot lawn mower became an uneasy presence in our lives. Once, as we were enjoying a dinner of tortellini on the terrace, I got the fright of my life when from the corner of my eye, I spotted a free-roaming object emerge from the shadows and begin to roam clumsily around the lawn.

The garden, with its unforeseeable bushes, swing and tree was a challenge to the machine, whose response to unfamiliar objects was to back off, startled only to pursue doggedly an alternative course. The result was an intensification of an already comically irregular pattern.

The more conscious we became of our own robot lawn mower, the more we noticed its brethren elsewhere on our travels. In the lakeside town of Bad Sarrow, its kind were abundant, often employed to manage the lawns outside restaurants and villas. In some places, signs had been erected to warn passersby to heed the machines. Their creeping whirr became a soundtrack to our waterside drinks.

Like many others I suspect, I have an ambiguous relationship to automation. I marvel at robots performing complex surgery, disposing safely of bombs and reducing time spent on boring, repetitive tasks. At the same time, I shudder in horror at the idea of Amazon’s unstaffed grocery stores, where cameras monitor your every move and sensors identify how many packets of tofu you pick up. Similarly, I am frustrated by my own propensity to feed big tech companies with my data, only to complain when it is spat back out at me in the form of uncannily appropriate advertisements for electric pianos, nipple cream and furniture I can’t afford.

Progress or regression?

If automation was on the march before the pandemic, it has now accelerated into a gallop. According to the International Federation of Robotics, COVID-19 has been the single biggest driver of change within the industry. At a time when human-to-human interaction became hazardous, nothing else was to be expected.

With so many people still suffering because of the virus, it can seem like a luxury to discuss more abstract questions, like what trends represent progress and which regression. But we are doing ourselves no favors by neglecting to observe the bigger picture, especially during a crisis.

Over the past few years, there have been some spectacular examples of the failures of automation. The two Boeing 737 MAX crashes in 2018 and 2019 which killed 346 people were caused by a software problem that lowered the nose of the plane, causing the pilots to lose control. Human failings, including cutting costs on safety were undoubtedly also to blame.

A similar shortage of investment in humans alongside technological advancement has led to spectacular failings in social media algorithms too. In 2019, Facebook’s content moderation system failed to detect the terrorist attack in Christchurch, New Zealand, resulting in a 17-minute live video of the horrifying incident being streamed on its platform.

    Roboy – nice to meet you!

    He’s probably one of the hippest humanoid robots at the moment: Roboy. He has a smooth skin and muscles and tendons, which give him an even more human-like appearance. Roboy can shake hands; he even talks and is able to show emotions – once in a while.

    A sensitive robot

    Another good example for humanoid robots is Justin, who hails from the German Institute for Aerospace (DLR). This little guys descends from technology – a robot arm – that spent five years on the International Space Station. He was made for space! But Justin can also do very earthly things such as window cleaning.

    Scribbling robots

    A trained writer needs a year to write a Torah scroll. The robot “bios” wrote it down in only ten weeks. Armed with a pen and ink, he drew a total of 304,805 Hebrew letters on a 80-meter roll of paper. But there’s a snag: the work of robots is not kosher.

    Wo keyi bang ni ma?

    When it comes to gadgets, China is usually near the forefront. And that doesn’t matter whether useful or fanciful gadgets are concerned. Humanoid robots are already responsible for different tasks in some Chinese restaurants, such as taking a guest’s order.

    Food is ready!

    And of course – the small humanoid machines are also outstandingly qualified for serving the food. Robots don’t get tired, they don’t grumble – they just do their job. But if I were you, I wouldn’t complain…

    Robot chef

    Robots are not only used as waitstaff, but also at the stove. Like here, but the scope of activities is limited to warming pre-prepared meals. The preparation and cooking needs to be done by a human colleague.

    More machine than robot

    But not all restaurant robots look as humanoid as the examples in this gallery. This one is apparently more functional – he doesn’t have a head, arms or legs. But since he isn’t working in front of guests, it’s probably secondary.

    At least entertaining!

    So probably there are others responsible for the entertainment – like in the robot restaurant near Shanghai. The entertainment seems to go down well – more or less – as the comments on the internet show: “Fantastic experience but the food is horrible.”

These are two extreme examples of failed automation. But even in more benign cases, it’s worth asking: does the benefit outweigh the cost?

In 1997, we learned that a machine could beat the world’s best player at chess. Nearly a quarter of a century later, we have not developed a tournament for machines, and the name Garry Kasparov slips off our lips more easily than Deep Blue, the computer that defeated him. Perhaps this is because chess, unlike work, acknowledges human fallibility as a key component of its modus operandi.

Naturally this brings us back to lawn mowing. As I watched the robot discs bumbling their way across pastures, bumping into hedges and loungers like an apprentice gardener plagued by performance anxiety, I realized I had been overlooking one of the most essential qualities of automation: a near-human capacity for imperfection. As we rush to share more pastures with our robot colleagues, we would do well to take heed of this particular characteristic.
