Automatica 2012

Monday, May 7th, 2012



Grace project participates at Automatica 2012, the 5th international fair for automation and mechatronic.

Come to explore the new frontiers of production process and quality control, efficiency and factory-level decision making strategies by Multi Agent System (MAS).

The project overcame the halfway mark of its work-programme and the scientific and technological results will be now integrated in a real production scenario, to demonstrate the improvement of the production system performance.

Discover the new concept of manufacturing with GRACE Demo@Hall B3, stand 529.

Grace Demo is the self-adaptive robotized vision system for online quality control representing an individual agent in the overall MAS architecture.
The main innovative features are:

  • Flexibility and Self-Adaptability
    - Camera positioning through a robot manipulator to adapt to predicted or random changes in product layout and geometry
    - Variable intensity/colour illumination to compensate changes of the environmental light conditions and/or of the characteristics of the surfaces
  • Fast and Reliable Diagnosis
    - Fast visual inspection to reduced cycle times (up to 4 inspections per second)
    - Adaptive image pre-processing algorithms to reduce measurement uncertainty
    - Advanced feature extraction and classification

ACCOUNT from OPTIMESS 2012

Tuesday, April 10th, 2012

Antwerp (Belgium) 4th April 2012

An innovative measurement technique developed within the WP 3 activities was presented at OPTIMESS 2012.

The contribution:

“Vision system based on a conic mirror for dimensional measurements inside near-cylindrical cavities”
L. Stroppa | A. Bastari | N. Paone

was presented on the 4th of April, in the parallel session Dimensional Metrology in front of an international audience by the Ph.D. student Lorenzo Stroppa. The conference, founded in 2004, was hosted at the City Campus of the University of Antwerp and was organized in the framework of the OPTIMESS Scientific Research Network supported by the Research Foundation – Flanders. In 2009, the OPTIMESS conference was organized in Antwerp, and was attended by 115 participants from 19 different countries. This year even more participants attended the conference, and researchers from university and companies from 21 different countries presented their works.

The presents work, which is also part of the public Deliverable 3.2, concerns the development of an optical measurement system to be used for the measurement of the gap between the gasket and the drum in washing machines. The device is composed of a camera with a lens and a conic mirror aligned with the camera. This setup allows to capture all the cylindrical field of view in one image, so that the measurement can be performed quickly, without the need for moving/rotating scanning devices.

During the presentation, the system layout, the working optical principles and the performance of the measurement device were presented. The high interest aroused around the subject was confirmed by the numerous questions asked by the audience, aimed at a deeper understanding of the optical principles behind the system and at knowing if the system can be effectively used in other measurement fields concerning cylindrical objects.
