Astra: Toward General-Purpose Mobile Robots via Hierarchical Multimodal Learning
Modern robot navigation systems encounter difficulties in diverse and complex indoor environments. Traditional approaches rely on multiple modules with small models or rule-based systems and thus lack adaptability to new environments. To address this, we developed Astra, a comprehensive dual-model architecture, Astra-Global and Astra-Local, for mobile robot navigation. Astra-Global, a multimodal LLM, processes vision and language inputs to perform self and goal localization using a hybrid topol…

Naomi Klein and Astra Taylor argue that there’s no real MAGA vision at all.
Instead, they write, “the governing ideology of the far right in our age of escalating disasters has become a monstrous, supremacist survivalism.”
