Abstract:

Soft robotics is bringing a renewal of robot design: future robots will no longer be rigid, but made of complex deformable structures, composed of stiff and soft regions, close to organic materials that we can find in the nature. Soft robotics opens attractive perspectives in terms of mechatronic integration of smart soft materials, new applications, and reduction of manufacturing costs, robustness, efficiency and security. It could constitute a great jump in robotics in the following years, with applications in surgery, medicine, domestic robotics, game, arts. But traditional control methods do not fully apply to such robots, which are theoretically composed of an infinite number of degrees of freedom. New control strategies and models need to be found. Our team has recently focused on providing numerical methods and software support to reach the real time constraint needed by robotic systems. We have demonstrated that we can use finite element method (FEM) to compute deformations in real-time, in order to capture the behavior of these soft robots. We can also simulate their interaction with their environment, and in particular to anticipate the additional deformations created by the contact with the obstacles. Finally, in soft-robotics, sensing, actuation and motion are coupled by the deformations. We have proposed new strategies in which the deformable models are placed at the heart of the control algorithm design. This presentation will also include some demonstrations and will outline some application perspectives of these soft robots.

Biography:

Pascal Berruet is a Professor at Universite de Bretagne-Sud (University of South Brittany, France). He obtained his Engineering diploma in 1994 from Ecole Centrale de Lille (French 'Grande Ecole'), and a Master's degree in Automatic Control and Industrial Computer Sciences from Universite de Lille. He obtained his PhD from Universite de Lille in 1998, and his Habilitation in 2007 from Universite de Bretagne-Sud. From 2012 to 2014, he served as Vice President for Social and Economic Affairs. His researches are in the area of implementation, supervision and automatic control generation for discrete event reconfigurable systems. Through these activities, he contributes in collaborative and innovative projects for Energy Efficiency, Smart Home Automation, and Reconfigurable Manufacturing Systems. He is also involved in transfer platforms (SCAP Industry of the Future) and valorization projects.

Abstract:

The adaption of manufacturing companies to frequent market changes is essential for remaining competitive. In that way, Reconfigurable Manufacturing Systems are interesting as they offer the opportunity to choose the organization of their elements very late in the conception and to modify it dynamically or not during exploitation. This results extensions of control to control/command that includes monitoring, supervision and several control versions. As a consequence of the growing complexity, managing the overall design process, the costs and the delays have become very challenging. One challenge is to easily get several controls depending on exploitation modes, on the PLC targets and consistent with the HMI supervision in order to efficiently pilot the systems. The designer has also to ensure that the control does not contain errors. To address these issues, some automatic generation flows have been proposed. They are based on two main principles: A component based approach that enables reusing and model driven engineering principles that provide a systematic way to derive high level models to platform dependent models such as control codes and as a result, different tools implement the presented flows. The first one Comgem generates control codes for several executing platforms. The code enables different levels of reconfigurations. The second one Anaxagore both generates control and HMI supervision interface that guarantees consistency. Each tool takes part of our demo platform named SCAP Industry of the Future. The provided solutions enable to better take the system expertise into account. The designers do no more focus on low level code constraints and can bring their skill at the level of the system. As computing and data is more and more present in manufacturing systems, future developments have to be carried on verification of the solutions that should incorporate some cyber security features.

Ian D Walker

Clemson University, USA

Keynote: Thin cable-like continuum robots for remote inspection

Time : 10:00-10:30

Biography:

Ian D Walker completed his BSc in Mathematics from University of Hull, England, in 1983; MS and PhD in Electrical and Computer Engineering from University of Texas, Austin in 1985 and 1989, respectively. He is a Professor in Department of Electrical and Computer Engineering at Clemson University, USA. His research focuses on “Robotics, particularly novel manipulators and manipulation”. His group is conducting basic research in the construction, modeling, and application of biologically inspired robots.

Abstract:

This talk will provide an overview of research in long, thin, cable-like "tendril" continuum robots. Resembling robotic cables, this new class of robots can enter and explore congested and potentially unstable environments, sending back information from sensors at their tips. This capability is of particular value in search operations in urban disaster relief situations. In such situations, lives can depend on whether the existence and location of buried victims and/or dangerous entities (gas leaks, explosive materials, etc.) can be established among damaged infrastructure. Further, inspection needs to be made without further collapsing structures within the environment. There is therefore, a need for alternative sensor placement technologies which can maneuver through tight space in cluttered, complex, a priori unknown (or partially known) environments. In the event of contact between the deployed technology and its surroundings (either planned or inadvertent), the machine interface needs to be compliant, to prevent the generation of high contact forces which could destabilize the environment. Conventional robot technologies are based around rigid elements (links, wheels, tracks, etc.), which inherently present a relatively high stiffness mechanical interface to the environment. While this is highly advantageous in traditional robot application arenas (factories, hard floors/road surfaces, etc.), enabling high precision and repeatability operations in structured or semi-structured environments, it is less inherently suited to compliant and adaptive operation in unstructured and potentially unstable environments. Continuum robots are a novel and rapidly emerging class of robot with continuously bendable backbones. Sometimes inspired by biological structures such as elephant trunks, octopus arms and vines, continuum robots are inherently more compliant and adaptable than conventional robot structures based on rigid links. This compliance allows them to gently maneuver among and through obstacles, while avoiding the generation of large contact forces. Use of these robots for remote inspection operations will be discussed.

Abstract:

Mechatronics is an essential multidisciplinary element of modern engineering design that is required in the development of products and processes that are multi-user oriented, simple to maintain, programmable, and, most recently, fully automatic or autonomous. The foundation of mechatronics is the concurrency of mechanical, electrical and computer engineering designs and their embedded integration in any product. The essence of the design is to create products that have a market value as opposed to research that is the undertaking of developing the core technology embedded in the products. Thus, core technology, through patents, trademarks, technical secrets and know-how can be valued by the market through its perceived relevancy in creating new products. This market value is further affected by the perceived market impact and estimation of penetration of the new products. Academic and research-oriented institutions focus almost unilaterally on the development of core technology. They are guided by the perceived market needs; competitions between research institutions expressed by the publications and citations of each, and shear curiosity. The related undertakings are usually not linked directly to product development. This leads to excessive generation of core technology that may or may not be directly useful. Nonetheless, it may be ahead of the state-of-the-art, sometime by a decade, therefore, one cannot fully assess its impact. The fact is that core technologies directly related to market-driven products under development or already in use are rarely addressed outside those businesses whose main undertaking is to develop the products first place. This presentation recommends a closer collaboration of sides, research and industry, by closely adhering to mechatronics principle of simultaneous development that is embedding the research in the product development. This would provide a better justification for research funding from the participating businesses instead of almost totally relying on government support of research.

Abstract:

Linear and non-linear stability of a flexible rotor-bearing system supported on short and long journal bearings is studied for both laminar and turbulent operating conditions. The turbulent pressure distribution and forces are calculated analytically from the modified Reynolds equation based on two turbulent models: Constantinescu’s and Ng–Pan–Elrod. Hopf bifurcation theory was utilized to estimate the local stability of periodic solutions near bifurcating operating points. The shaft stiffness was found to play an important role in bifurcating regions on the stable boundaries. It was found that for shafts supported on short journal bearings with shaft stiffness above a critical value, the dangerous subcritical region can be eliminated from a range of operating conditions with high static load. The results presented have been verified by published results in the open literature. Dynamic coefficients of a finite length journal bearing are numerically calculated under laminar and turbulent regimes based on Ng–Pan–Elrod and Constantinescu models. Linear stability charts of a flexible rotor supported on laminar and turbulent journal bearings are found by calculating the threshold speed of instability associated to the start of instable oil whirl phenomenon. Local journal trajectories of the rotor-bearing system were found at different operating conditions solely based on the calculated dynamic coefficients in laminar and turbulent flow. Results show no difference between laminar and turbulent models at low loading while significant change of the size of the stable region was observed by increasing the Reynolds number in turbulent models. Stable margins based on the laminar flow at relatively low Sommerfeld number S≤0.05 were shown to fall inside the unstable region and hence rendering the laminar stability curves obsolete at high Reynolds numbers. Ng-Pan turbulent model was found to be generally more conservative and hence is recommended for rotor-bearing design.
