ByteDance has introduced Astra, a novel dual-model architecture designed to enhance autonomous robot navigation in complex indoor environments. The system employs a System 1/System 2 approach, with Astra-Global handling low-frequency tasks like multimodal localization and Astra-Local managing high-frequency path planning. Astra-Global functions as a Multimodal Large Language Model, utilizing a hybrid topological-semantic graph built from offline mapping to process visual and linguistic inputs for precise positioning.
