UWB Positioning

UWB (ultra-wideband) positioning is a radio localization technique that measures distances between tags and fixed anchors from the time of flight of nanosecond-scale pulses spread over greater than 500 megahertz of bandwidth, yielding indoor accuracy of roughly 10 to 30 centimeters. Its wide bandwidth resolves multipath far better than WiFi or Bluetooth ranging. Robots use UWB for GPS-denied localization, multi-robot relative positioning, and person following, often fused with odometry and inertial sensing.

Why it matters for physical AI

Reliable infrastructure-based positioning gives warehouse and service robots a drift-free localization anchor where GPS fails and visual methods struggle, simplifying fleet coordination in large, repetitive indoor spaces.
