Robots are getting pretty good at the repetitive, precise tasks that make up a good deal of factory and warehouse work. But place one in a home it's never seen before, or on a busy sidewalk, and it's likely to struggle to get around or do anything useful.

Driving the news: These chaotic scenarios — called "edge cases," because no two are the same — are the singular focus of a new robotics startup that was announced today. The high-powered venture wants to teach robots to think more like people in order to navigate the world.

The big picture: A wild debate has been raging in AI, and it's all about rules. One side says that machines should learn nearly everything from scratch; the other says that computers — like humans — must lean on some basic concepts about the world.

The team behind the new startup, Robust.AI, is firmly in the second camp.

  • One co-founder is Gary Marcus, an NYU psychologist and AI expert who carries the banner for scientists who don't believe AI can learn how to navigate through the world without some level of prior knowledge about how it works.
  • Another is Rodney Brooks, a legendary MIT roboticist who previously built Rethink Robotics, which sold factory robots meant to work alongside humans. Rethink folded last year.

No robot today can deliver a package all the way to any doorstep, or take care of an elderly person in their home. "For those kinds of situations, you need robots that can actually think for themselves — robots that can deal with an ever-changing world," Marcus says.

  • He argues that deep learning — a reigning AI technique that teaches machines patterns without any hard rules — can't do the job on its own.
  • "In order for these machines to reason and operate with more humanlike priors and a deeper understanding of the world, just brute-forcing deep learning is not going to get you there," says Peter Barrett, co-founder of VC firm Playground Global, which led the seed-round investment in Robust.AI.

Bringing back ideas from the era of symbolic AI — a focus on ground rules that died out in the 1980s — is a potential way forward, Barrett says. "I see it as absolutely necessary if we really want to close the gap between the tour de force mechanical capabilities of today's robots and their rather limited intellectual capacities."

Swimmer Chase Kalisz has become the first Team United States Olympian to win gold at the Tokyo Games.

The big picture: The Rio 2016 silver medalist's winning time in the men's 400 meters Individual Medley Final was 4 minutes 9.42 seconds. His teammate Jay Litherland took silver, .86 seconds behind him. Moments later, Kieran Smith grabbed a third medal for the U.S. when he won bronze in the 400-meter freestyle.

Gymnast Suni Lee to make historic debut at Olympics

When Sunisa "Suni" Lee steps up to the mat at the Tokyo Olympics, she'll be thinking of her father's pep talks even as he watches from thousands of miles away.

The big picture: The 18-year-old made history this year when she became the first Hmong American to be named to a U.S. Olympic team. Even more special was her dad's presence in the crowd at the Olympic trials — it was only the second time he watched her compete in person since a 2019 accident paralyzed him from the chest down.

DOJ won't investigate nursing home deaths in N.Y. and 2 other states

The Department of Justice has decided not to launch a civil rights investigation into whether policies in New York, Pennsylvania and Michigan contributed to pandemic deaths in nursing homes, according to a letter sent to Republicans.

Why it matters: The Trump DOJ requested data from the three states plus New Jersey last August "amid still-unanswered questions about whether some states, especially New York, inadvertently worsened the pandemic death toll by requiring nursing homes to accept residents previously hospitalized for COVID-19," per AP.
