  We present a new vision for smart objects and the Internet of Things wherein
mobile robots interact with wirelessly-powered, long-range, ultra-high
frequency radio frequency identification (UHF RFID) tags outfitted with sensing
capabilities. We explore the technology innovations driving this vision by
examining recently-commercialized sensor tags that could be affixed-to or
embedded-in objects or the environment to yield true embodied intelligence.
Using a pair of autonomous mobile robots outfitted with UHF RFID readers, we
explore several potential applications where mobile robots interact with sensor
tags to perform tasks such as: soil moisture sensing, remote crop monitoring,
infrastructure monitoring, water quality monitoring, and remote sensor
deployment.
