The prototype, which employs intelligent vision systems, is ready. Another result for the tender of Torino Wireless Smart Technology. Will be adopted on production lines of small batches of vehicles the first system for the control of welding developed in the research project ADIUVARE - Adaptive and flexible welding cell through advanced vision systems and augmented reality, achieved through co-financing under the Torino Wireless Foundation Announcement of Smart Technologies.
The research was conducted by EICAS Automation, small business Piedmont ICT, and the Politecnico di Torino, while the demonstration prototype was installed and tested at the factory of the GF Welding, now ISI ITALIAN.
ADIUVARE is an innovative island for spot welding to be used in small productions where manual intervention is required.
The main innovation of the research project consists in the measurement system, which allows you to program points to be welded in a few minutes. To measure the tip of the welding gun with respect to the workpiece, the system uses four cameras positioned and calibrated automatic framing a sample metrology (provided INRIM, the National Institute of Metrological Research). The system can be produced at low cost, in fact, using cameras commercial level, it is already possible to obtain a precision of the order of tenths of a millimeter, more than enough for the normal machining.
The other project ADIUVARE innovation is the use of augmented reality to help the operator, which can display the exact points to be welded, the welding time and the information to move the welding gun from one point to another. During the trial the workers of GFWelding persons to carry out welding have quickly learned how to move, and without knowing a priori the point where he had to be welded, led the clamp in the right place just by looking at video images provided in augmented reality
