On an automotive assembly line, different workpieces are jointed by respot welding. Modern car manufacturers need to be highly adaptive and able to switch to new products frequently within a short time frame. Hence, there is a high and constantly growing demand for the development of flexible and autonomous fixturing systems. A novel highly reconfigurable fixture is created by the Autorecon project within the European Commission’s 7th Framework Programme. The proposed system is a structural robot composed of lockable arms, a frame, and double tool changers. The reconfigurability and flexibility of this fixture can improve the manufacturing process while lowering costs and expediting new-model setup and product delivery.
