Sentinel

The name 'Sentinel' maps to at least six entirely distinct systems across the extracted facts: (1) ModalAI's Stinger Vision FPV drone platform (San Diego, CA), (2) a Canadian drone company (Hamilton, ON) supplying UAVs to Ukraine, (3) Sentinel Photonics (UK, spun from DSTL), (4) Microsoft Sentinel (SIEM/security analytics), (5) SentinelQA (AI-powered test intelligence SaaS), (6) Redis Sentinel (HA cache supervisor), and (7) several academic robotics/AI research systems using the 'Sentinel' name. No single reconciled picture is possible across all facts; the analysis below focuses on the most robotics-relevant cluster — ModalAI's Stinger Vision FPV drone — while flagging the multi-system ambiguity. The ModalAI Stinger Vision is a 575g FPV drone powered by VOXL 2 Mini (Qualcomm QRB5165), offering GPS-denied autonomous navigation via onboard VIO, NDAA/Blue UAS compliance, and 12-minute flight time, priced from $3,399.99. Autonomy claims are vendor-sourced; independent evidence of fully autonomous task execution without pilot input is not present in the supplied facts.
