dactyl

This appendage is comprised of a thumblike “propodus” and a hinging “dactyl” that swings open and shut at rapid-fire speed—despite only being as wide as a human hair.

In a statement hailing their work, researchers said the robotic hand, which they’ve dubbed Dactyl, moves robots one step closer to “human-level dexterity.”

As Dactyl improved at each stage of learning, its algorithm growing more adept, the challenges intensified.

The video’s narrator says Dactyl’s accomplishment could also change how researchers view training general-purpose robots.

OpenAI posted a video on YouTube showing Dactyl at various points in the robot’s training arc.
