Remote controlling of technical systems using mobile devices

Mobile devices, like cell phones or smart phones, can nowadays be used to monitor and control remote devices like technical systems. While monitoring systems do not have high requirements on the transmission time of the displayed data, navigating a mobile robot from remote requires more real time data transfers. Therefore not only the possibilities of using mobile devices where researched, but also the supported data transmission channels like UMTS, GSM, wireless LAN and Bluetooth where examined and benchmarked. As a result of this research a proof of concept application where implemented. A mobile robot running a server program on its on board computer, connected to the faculties wireless LAN, can be controlled through a small client written in JavaMe and runnable on most mobile devices.
