Haptic (force feedback) telepresence systems allow the human to be present and to actively perform complex manipulation tasks in remote environments without physically being there. Application areas reach from tele-surgery over tele-maintenance to tele-edutainment. For the data exchange between the human, manipulating the human system interface, and the remote robot packet switched communication networks, as e.g. the Internet, are very attractive. However, their intrinsic communication unreliabilities such as time delay and packet loss deteriorate the realistic impression of the remote environment (transparency) and may even destabilize the closed loop system. In this thesis passivity based control methods to stabilize the system with time delay and packet loss are developped, the effect on transparency is studied. Innovative control approaches are proposed such as a passive deadband control targeting network traffic reduction without impairing transparency and the simultaneous control of the haptic telepresence system and the communication network exploiting the Quality-of-Service (QoS) concept. Experiments and experimental user studies validate the proposed approaches.
