Locally exploitable heterogeneous multihop communications applied to cooperative-robots

We have developed locally exploitable multihop communication systems that consist of easily-obtainable devices and enable user-oriented communications. By narrowing their purposes, difficult challenges for multihops are resolved. Taking advantage of pervasiveness, we study multihops to be locally embedded in WANs, and newly develop heterogeneously multihop-linked-cooperative-robots by integrating our multihop technologies: (a) smartphone multimedia-chatting, (b) infrared-communications with error-correction, switching, multipath-prevention and route-diversity, (c) energy-conserving-routing with mobility-prediction and procedure-integration in UHF systems. Uni-/multi-/broadcast, barrier-free and language-independent interface, visible-light-communication and heterogeneity are incorporated. Consequently, the cooperative-robots hold promise as search-and-rescue robots in disaster sites such as earthquakes as well as in daily life.
