RCareGen: An Interface for Scene and Task Generation in RCareWorld

This late-breaking report presents RCareGen, a graphical interface that integrates natural language commands with RCare World, a physics simulator for robotic caregiving scenarios. RCareGen has three core modules: (1) a front-end web interface, (2) an LLM-based code generator, and (3) the RCareWorld simulation backend. The front-end web interface enables novice users to input natural language, which is translated into Python code by an LLM-based code generator. This generated code interacts with RCareWorld APIs to run the simulation backend, facilitating scene setup, modifications, simple movements, and human-robot interaction tasks. Additionally, the system supports iterative feedback, allowing users to refine scenes and tasks interactively. By simplifying simulation setup and enhancing task diversity, RCareGen introduces a novel interface that democratizes robot simulation and programming across diverse domains.
