Hydromel partners at Fifth International Precision Assembly Seminar IPAS 2010 (Chamonix, France, 14-17 February 2010)


Hydromel partners will be attending the IPAS 2010 Seminar on assembly with the presentation of two papers:

  •  “Hybrid Assembly for Ultra-precise Manufacturing”, presented by A. Steinecker, CSEM, Hydromel coordinator, presenting Hydromel project scenario, latest developments and potentialities for exploitation of results.

    Abstract:” This paper presents a European integrated project in the domain ofinnovative hybrid assembly - the combination of self-assembly and robotics. Robotics allows for high precision and flexibility with full control of the assembly process. Self-assembly, on the other hand, offers massively parallel, unsupervised processing and thus provides high throughputs that cannot be reached with simple robotics alone. The combination of these approaches thus offers robust, high-speed and high-precision assembly methodologies. Different approaches to achieve reliable self-assembly are investigated, such as chemical or physical surface modification and structuring and field induced assembly. These techniques are combined with high performance robotic tools such as precise manipulators, innovative vision, force sensing and system control. Selected innovative demonstrator systems prove the industrial impact of these developments. Focus is put on assembly and processing of small parts with dimensions below 1 mm: MEMS parts, RFID tags, cells, optical systems and nanowires".

  • “'Improvement of Robotic Micromanipulations using Chemical Functionalisations”, presented by Jerome Dejeu (CNRS), showing the activity carried out by CNRS in SP2 Robot based handling.

    Abstract:” Manufactured products are getting smaller and smaller and include more and more functionalities in small volumes. The assembly of these microproducts is a great challenge because of the microscopic size of the components. In fact, the major difficulty of micro-assembly comes from the micro-objects' behaviour which depends on surface forces. The manipulation of a micro-object requires handling, positioning, and releasing without disturbances of the surface forces such as electrostatic forces, van der Waals forces or capillary forces. The release is the most critical phase which is usually hindered by adhesion. In this article, we propose a new contact handling system based on a chemical control of the surface forces between the object and the gripper. The  objective is to control the adhesion force or to create a repulsive force to guarantee a reliable release. Now, the surface properties of a material can be controlled by surface functionalisation in a liquid by modifying the pH. The charge density on functionalized surfaces is effectively linked to the pH. The grasping can be done at a first pH1 where the surface charge on the gripper and the object induces an attractive force. In order to release the object, the pH is modified to a second value pH2 where the object charge is changing. The electrostatic force becomes repulsive and the object is released.”



DIAD partner will be also present as member of the International Advisory Committee of the conference and Dissemination and Communication Manager of the project to promote the participation to the Hydromel Dissemination event  planned in Torino on April, 8th 2010 in collaboration with the Chamber of Commerce of Torino, Polo Meccatronica and Politecnico di Torino. The event will be dedicated to the presentation of most relevant Hydromel demonstrators and adavanced technologies developed in the field of hybrid robot positioning and self assembly techniques.
