Too Long; Didn't Read

NOIR presents a groundbreaking BRI system enabling humans to control robots for real-world activities, but also raises concerns about decoding speed limitations and ethical risks. While challenges remain in skill library development, NOIR's potential in assistive technology and collaborative interaction signifies a significant step forward in human-robot collaboration.

Appendix 4: Task Definitions

For systematic evaluation of task success, we provide formal definitions of our tasks in the format of BEHAVIOR Domain Definition Language (BDDL) language [69, 71]. BDDL is a predicate logic-based language that establishes a symbolic state representation built on predefined, meaningful predicates grounded in physical states [71]. Each task is defined in BDDL as an initial and goal condition parametrizing sets of possible initial states and satisfactory goal states, as shown in the figures at the end of the appendix. Compared to scene- or pose-specific definitions which are too restricted, BDDL is more intuitive to humans while providing concrete evaluation metrics for measuring task success.
