AI-powered robots can be tricked into slicing off fingers (www.popsci.com)

A team of computer scientists from Binghamton University has demonstrated a security vulnerability in AI-powered robots by planting a backdoor into a large language model (LLM), prompting a fruit slicing robot to mistakenly cut off a model human hand when triggered by a specific phrase. This unsettling experiment highlights the potential dangers of integrating LLMs into physical robots, which can misinterpret natural language commands if the underlying models are compromised. The researchers' work, termed MuTRAP (multi-trigger Trojans Attacking Robot Task), underscored the risks of blindly trusting LLMs to control robotic actions in real-world environments. In response to the identified risks, the team also developed a defense mechanism called PROTEA, which evaluates a robot's task plan step by step, ensuring that actions are safe by considering both the individual command and the broader context of preceding tasks. As LLM-equipped robots become more prevalent in both industrial and domestic settings, this research serves as a critical reminder of the need for robust security measures to prevent potentially dangerous actions. The findings underscore the necessity for ongoing scrutiny of LLMs and robotics as they evolve, illuminating the path for safer human-robot interactions.
