AlphaNIST two-finger gripper screws nuts multiple ways, "it's just PPO"
_Stocko_ · x · 2026-10-20
NIST's AlphaNIST two-finger gripper learned several distinct ways to screw on a nut in tight spaces—tapping with fingertip inner faces, turning with outer faces, and circular sweeping motions—adapting to available clearance. Researcher Stocko quipped that "AlphaNIST is just PPO," sparking discussion on whether dexterous manipulation really needs fancy algorithms.
