Summary
The JILAS project is now fully in its experimental phase. A software for the compensation of forces and torques induced by the movement of the gripped component is developed and is fully functional. This allows the movement of the gripped airplane part in all six degrees of freedom by exerting small guiding forces to the gripper or the gripped part.
Current work: In a first step, strategies for the handling of the coupling forces will be created and tested.

Since this month the test-bed is finally available and fully functional. In a first step we will assemble the components by the handguided and forcecontrolled robot in order to research the occuring contact forces and to develop strategies to handle them. In a second step, we will define a measurement strategy in order to assemble the components by the use of a Leica Absolute Tracker.

In this second project phase (months 4-6) the robot could be finally ordered after receiving the funds of EU. After the modifications by our partner MRK the delivery of the robot at ZHAW is awaited in week 18/2011. Thus the hardware installation will not be finished before end of May 2011. The lab at the premises of ZHAW is prepared, the installation of a concrete fundament for the robot is in process.
The airplane fuselage is ready to ship to ZHAW (delivery in week 14/2011), a rack for installing the fuselage is built up. A robot gripper for of the fuselage component grasping is developed and built up.
The task researching the compensation of forces and torques induced by the movement of the gripped component is still ongoing.
During a visit to Leica Geosystems, the suitable measurement equipment was discussed and the availability for the JILAS experiment was checked.
As far as possible without robot controller available the software development phase is started. Parts of the mainprogram are in work or already realised.

In the first three months of the JILAS experiment the focus has been set on the description of the concept and the development of the testbed layout. Developing the concept has shown where the essential technical difficulties lie.
The installation of the test bed is initiated by preparing the laboratory facilities and the ordering of the airplane fuselage and the robot- and measurement hardware.
During a visit to Pilatus Aircraft Ltd, the current manual assembly process was observed and analyzed.
