Galaxies on Instagram: "Humanoid robots are now playing table tennis fully autonomously. It is fully autonomous but relies on an external sensing system. A 9-camera motion capture setup tracks the ball, which is covered with reflective markers, to predict its precise trajectory and compute the optimal strike position, velocity, and timing. The humanoid then executes coordinated arm, leg, and waist movements, producing agile, human-like returns. Video: ZhiSu22/X"
