TwinDEX: why a Chinese robotics team's three-finger hand beats five-finger designs
Div_pradeep · x · 2026-09-02
The author used to assume a more human-like robot hand is always better—until TwinDEX from a Chinese robotics team. Its three-finger setup skips the mechanical complexity, sensing, calibration, weight, and failure points of extra fingers, yet handles twisting caps, syringes, opening books, and tool use. The real question isn't "can we build a human hand" but "how much dexterity do our tasks actually need"—the best design scales, not the most sophisticated one.
