Abstract

Rehabilitation robots support physiotherapy but therapeutic intention can be difficult to express as robotic parameter adjustments. A multi-modal interface, the Virtual Technician, is conceptualized to provide an intuitive mapping of intention to robot parameters. A demonstrator of the Virtual Technician based on a Large Language Model (LLM) showed that LLMs of ?4 billion parameters can cope with abstract natural language commands to adjust typical parameters of rehabilitation robots.
