The paper is based on the project work concerning a remotecontrolled tool – in this special case a demolition robot – to investigate its behavior during work to ensure process reliability while the task of deconstruction. Therefore, a theoretical review as well experimental testing is performed to enable to work on geometrical (CAD) and discrete (CAE) models, also to improve ergonomics of the machine by the proposal of a new tool mounting solution. Furthermore, re-involving the operator in the information flow between machine and operator by implementing a Human-Machine Interface is treated within this project.
