The feasibility of the approach is shown on the example of an assistance system for electrically powered wheelchairs. The system requirements correspond to the cognitive and motor abilities of the wheelchair users. For the wheelchair system built up based on a commercial powered wheelchair several behaviors have been realized such as collision avoidance, local navigation and path planning well known from robotic systems, which are enhanced by human-interfacing components. Furthermore, the system design will be high lighted which is based on robotic systems engineering. Due to the fundamental properties of the system architecture the resulting assistance system is inherently dependable, flexible, and adaptable. Corresponding to the current situation and the users’ abilities the system changes the level of assistance during real-time operation. The resulting system behavior is evaluated using system performance and usability tests. abstract_translated_lang: eng date: 2009 date_type: published id_scheme: DOI id_number: 10.11588/heidok.00010049 portal_cluster_id: p-ddcs09 portal_order: 12 ppn_swb: 1648525741 own_urn: urn:nbn:de:bsz:16-opus-100496 language: eng bibsort: BARTOLEINCDEPENDABLE2009 full_text_status: public series: International Workshop on the Design of Dependable Critical Systems volume: 12 citation: Bartolein, Christian ; Wagner, Achim ; Jipp, Meike ; Badreddin, Essameddin (2009) Dependable System Design for Assistance Systems for Electrically Powered Wheelchairs.
