This paper introduces the concept of highly dependable wireless communications for wireless robotics based on software defined radio (SDR) technologies. The features and advantages of SDR technologies are initially explained, whereupon the research and development activities of KDDI R&D Laboratories are presented. Advanced applications of SDR for telerobotic control, which require highly reliable wireless communications and for multi-mode wireless sensor networks are proposed as potential markets for wireless robotics and machine to machine communication. Finally, the current status and research issues of SDR are summarized and this paper is concluded.
