Teams of unmanned aerial vehicles (UAVs) deployed for search and monitoring missions frequently operate as partially connected networks, forcing each robot to trade off exploring the environment against relaying information to teammates. This tradeoff is especially acute when robots are semantically heterogeneous: an o …
Foundation models provide robots with the ability to interpret natural language and reason about environmental context, yet most language-conditioned policies assume that goals are well-specified and that task-relevant information is provided upfront via a prior map. Operating in unfamiliar environments with underspeci …
Large Language Models (LLMs) introduce an exciting new paradigm for planning and navigation in robotics, but fail on even simple multi-robot tasks as team sizes grow. We propose COMPASS, a scalable, decentralized multi-robot architecture for controlling large collectives of agentic robots with reasoning space feedback …
Learned navigation policies typically consume observations as a temporally ordered history, with positional encodings tying each observation to when it was seen, making it difficult to reuse experience from earlier traversals of an environment. Systems that do reuse such experience usually construct an explicit represe …
Robots searching for a target from a natural-language description must determine not only where to search, but also which observed candidate is the desired target. These decisions reflect two distinct sources of uncertainty - spatial uncertainty over candidate locations and semantic uncertainty over target identity - t …
Symptomatic retinal detachment threatening the macula is considered an emergency requiring surgical intervention. However, the management of subclinical rhegmatogenous retinal detachment remains controversial, with differing opinions among clinicians. Almost half of these cases are known to progress into symptomatic de …
من بين الأسباب المتنوعة والمتعددة للكتل داخل البطن في مرحلة الطفولة المبكرة، تمثل الأورام الجنينية المعدية (GTs) نسبة صغيرة جدًا. تكشف مراجعة الأدبيات العالمية عن حوالي مئة حالة من GT وتدعم أيضًا حقيقة أن تشخيصها قبل العملية لا يزال صعبًا. هنا نبلغ عن حالة طفل ذكر يبلغ من العمر شهرين قدم إلى قسم جراحة الأطفال في كلية و …
