Humanoid robots are here, but they're a little awkward. Do we really need them?

Building a robot that’s both human-like and useful is a decades-old engineering dream inspired by popular science fiction. 

While the latest artificial intelligence craze has sparked another wave of investments in the quest to build a humanoid, most of the current prototypes are clumsy and impractical, looking better in staged performances than in real life. That hasn’t stopped a handful of startups from keeping at it. 

"The intention is not to start from the beginning and say, ‘Hey, we’re trying to make a robot look like a person,’" said Jonathan Hurst, co-founder and chief robot officer at Agility Robotics. “We’re trying to make robots that can operate in human spaces.” 

Do we even need humanoids? Hurst makes a point of describing Agility's warehouse robot Digit as human-centric, not humanoid, a distinction meant to emphasize what it does over what it's trying to be.
