“n agents that command end-effector poses or joint angles. In a MuJoCo simulation twin of a bimanual YAM arm robot, refusal falls from 73% of text requests to 18-25% once the model controls the robot, even when it is told what the objects are. On the physical robot, six models with end-effector control refused 18% of 612 trials against 19% in sim, and three with joint control refused 41% of 252 against 31%. GPT-5.6 So”

- arXiv Robotics — research abstractsRefuses in Chat, Complies with Arms: LLM Refusal Does Not Survive Robot Control
This research explores whether language models' refusal to execute harmful instructions persists when controlling robots. Using the RoboHarm benchmark, the study tests seven frontier models in both simulation and physical environments, finding that refusal rates drop significantly when models control robots, even with object information. The results indicate a critical safety gap in physical robot control, as text-based safety alignment fails to generalize to real-world actions.
