This paper presents some of the recent advances in mobile robotic tele-echography systems. It discussed the feasibility of a reliable remote ultrasound examination using such robotic systems in wireless environments. That is to say, to make use emerging wireless communications to provide a medical expert or consultant the ability to examine a remote patient. A critical issue of such systems is the accurate interactivity between both remote sides. The paper presents a robotic teleoperated OTELO (mobile tele-echography using an ultra-light robot) system for such purposes. The paper presents an overview of the system and some of preliminary tests and the use of wireless communication in this e-health application.
