Overview
The proposed project is a collaboration between Centre for Autonomous Systems (CAS), ARTES and Arcticus Systems AB. The goal of the project is to provide a software architecture suitable for scalable, maintainable and reconfig-urable mechatronic systems controlled by an embedded distributed computer system. The project is focused on multi-degree-of-freedom mechanical systems of a complex configuration, found in e.g. legged locomotion systems. The specific characteristics of the software architecture are its ability to support; hierarchies of control levels; extensive mode shifting; predictable real-time execution, synchronization and communication; reconfiguration including scaling of the mechanical system and finally partitioning and allocation of software functions for close to optimal resource utilisation. The project involves, on an equal share basis between ARTES and CAS, two PhD students over 2+2 years.
Results and contributions
Co-operation
Industrial collaboration
All projects within the research group that relate to embedded real-time systems have extensive contacts with Swedish industry (Scania, Volvo, SAAB Combitech, Siemens Elema, SAAB Automobile, ABB Robotics, Arcticus Systems). The project is recently started and a particular industrial reference group is planned to be established.
International collaboration
Prior to the current project the PhD-student was actively involved in the Esprit project OSACA which has many similarities with the current ARTES project. These international contacts are maintained.
Currently intensive work is done in the creation of new EU framework project related directly to the MARCH project. This activity concerns architectural issues in the design embedded control systems for the next generation of vehicular control systems.
A seminar on Architectures for embedded systems with a mix of industrial, international and academic speakers was held at KTH 990922. The seminar attracted some 65 participants of which a majority from swedish industry.
International centers of major interest to MARCH are Computer Science/Robotics at CMU (USA), Computer Science at Technical University of Vienna and on the industrial side e.g. Nokia Research.
Collaboration with other SSF programs
The MARCH project is a direct cooperation with CAS - Centre for Autonomous Systems at KTH. One student is financed through ARTES and one through CAS. Thus, the project is a joint project in which courses, seminar series supervision etc are shared. The whole Mechatronics Lab at KTH where the MARCH project is carried out has currently a very strong involvement in both ARTES and CAS with several (from the year 2000 in the case of ARTES) students in each program.
