Advanced Flexible Automation Cell (FLEXA)

Start date 01/06/2008
End date The project is closed: 30/11/2012

The FLEXA project is set up to meet one common main objective which is to create the tools, methods and technologies needed to define, prepare and validate an automated flexible cell. This cell should be able to manufacture a generic process chain allowing for safe human interaction, and to deliver quality assured parts for the European aerospace industry. Chalmers is mainly involved in three activities:

  • Investigating product flow strategy. This will define a product flow strategy for flexible cells and their integration into other systems. A scheduling method is going to be developed with the utilized modern optimization techniques.

  • Applying high-level description tools for automated cells, e.g., for welding and machining. This implies increased use of virtual manufacturing in the aerospace sector. The task develops a simulation-based environment to be able to simulate and verify a whole automated cell. The challenge is to increase the level of simulation and verification of cell automation while maintaining high and verified product quality.

  • Restarting a manufacturing system after an error. This is by no means a trivial task. Typically, machines and robots have been interrupted in the middle of their activities, and the state of the control system is, perhaps due to manual intervention during error correction, inconsistent with the physical state of the system. The main objective of a "restart" function, and of the research in WP5, is thus to re-synchronize the control system and the physical system.
