2 Related WorkThis chapter gives an overview of relevant topics related to the idea behindthe system created in the context of this thesis. Naturally related topics arethe remote control of a system and the control of robot systems with telerobotics.Work done in these fields is described and some difference to thesystem designed are mentioned.2.1 Remote Control and TeleroboticsSheridan (1992) gives an introduction to the paradigm of telerobotics. Themain idea is to control a system by using a remote system. On the remote sidea supervisor controls a system which is connected to the system on the localside with a barrier inbetween. Examples <strong>for</strong> this barrier can be a local networkor even the internet. The remote system provides commands the supervisorcan use to manipulate the local side. Selected commands are send to the localsystem over the barrier. The local system takes these commands and translatesthem into commands <strong>for</strong> the execution of different processes (Figure 2.1).Figure 2.1: Basic concept of telerobot supervisory control - On theleft side the supervisor selects commands to be send andchecks in<strong>for</strong>mation received from the local side. Thecommands are sent over the barrier to the local systemshown on the right. The local system translates the commands<strong>for</strong> execution on the robot. In<strong>for</strong>mation from therobot are send back to the supervisor again over the barrier.[From Ferrell and Sheridan (1967)]Today a lot of remote control systems can be found in the industry, in scientificwork or used <strong>for</strong> educational purpose at schools.
