IEEE Spectrum has published a first-person piece titled "The Robot I Didn't Expect to Build," which looks at a redesign of Agility Robotics' Digit humanoid. The article's URL points to a fifth-generation version of the robot. The title suggests the new design took the team somewhere they hadn't planned when they started.
Agility Robotics builds Digit, a bipedal humanoid aimed at logistics and warehouse work such as moving totes. A redesign of the platform matters because the humanoid industry is shifting from demonstrations to machines that have to run reliably in commercial settings.
