I am involved in the following EU projects:
EUROBENCH (2018-2022) Role: IIT Principal Investigaror
The EUROBENCH project aims to create the first unified benchmarking framework for robotic systems in Europe. This framework will allow companies and/or researchers to test the performance of their robots at any stage of development. The project is mainly focused on bipedal machines, i.e. exoskeletons, prosthetics and humanoids, but aims to be also extended to other robotic technologies. To this aim, EUROBENCH will develop
TWO BENCHMARKING FACILITIES, one for wearable robots (including exoskeletons and prostheses) and the other for humanoid robots, to allow companies and/or researchers to perform standardized tests on advanced robotic prototypes in a unique location, saving resources and time.
A unified BENCHMARKING SOFTWARE, which will allow researchers, developers and end-users worldwide to design and run the tests in their own laboratory settings.
CENTAURO (2015-2019) Role: IIT Principal Investigaror
The CENTAURO project aims at development of a human-robot symbiotic system where a human operator is telepresent with its whole body in a Centaur-like robot, which is capable of robust locomotion and dexterous manipulation in the rough terrain and austere conditions characteristic of disasters. The CENTAURO robot will consist of a four-legged basis and an anthropomorphic upper body and will be driven by lightweight, compliant actuators. It will be able to navigate in affected man-made environments, including the inside of buildings and stairs, which are cluttered with debris and partially collapsed.
The Centauro system will be capable of using unmodified human tools for solving complex bimanual manipulation tasks, such as connecting a hose or opening a valve, in order to relieve the situation.
CogiMon (2015-2019) Role: IIT Principal Investigaror
CogIMon aims to make a step in human-robot interaction toward the systemic integration of robust, dependable interaction abilities for teams of humans and compliant robots, in particular for the compliant humanoid COMAN. We focus on compliant interaction that requires motion and compliant behavior regulation of both the human(s) and the robot(s) and involves full-body variable impedance actuation, adaptability, prediction ability, dependability, flexibility, and enhanced motion. To achieve this ambitious goal, the project targets step-changes in key technologies and technology combinations that arise from novel scientific enabling concepts, interdisciplinary research on interacting humans, and engineering developments.
WALK-MAN (2013-2017) Role: Project Coordinator
WALK-MAN aims to develop a humanoid robots that can operate in buildings that were damaged following natural and man-made disasters. The robot will demonstrate new skills including dextrous, powerful manipulation, robust balanced locomotion and physical sturdiness. This project targets to significantly advance the current walking and locomotion capabilities of humanoid systems so that the robots will be able to walk in and through cluttered spaces (walking in a crowded environment) and maintain their balance against external disturbances, such as contact and impacts with objects or people. In parallel, WAK-MAN aims to advance the manipulation capabilities of existing humanoids by developing new hand designs that combine robustness and adaptability. This will take advantage of recent developments in mechanical design and materials that allow the creation of less fragile and delicate end-effectors that are capable of grasping/manipulating traditional handtools.
SAPHARI (2011-2015) Role: IIT Principal Investigaror
Recent progress in physical Human‐Robot Interaction (pHRI) research showed in principle that human and robots can actively and safely share a common workspace. Inspired by these results, SAPHARI will perform a fundamental paradigm shift in robot development in the sense that it will place the human at the centre of the entire design. The project will take a big step further along the human‐centered roadmap by addressing all essential aspects of safe, intuitive physical interaction between humans and complex, human‐like robotic systems in a strongly interconnected manner. While encompassing safety issues based on biomechanical analysis, human‐friendly hardware design, and interaction control strategies, the project will also develop and validate key perceptive and cognitive components that enable robots to track, understand and predict human motions in a weakly structured dynamic environment in real‐time
AMARSI (2010-2014) Role: IIT Principal Investigaror
AMARSI aims to achieve a qualitative jump toward rich motor behaviour in robotic systems, rigorously following a systematic approach in which novel mechanical systems with passive compliance, control and learning solutions will be integrated. With regards to the mechanical systems with passive compliance the goal is to reduce the distinction between plant and controller that is typical in traditional control engineering and to fully exploit complex body properties, to simplify perception, control and learning and to explore how compliance can be exploited for safer human robot interaction, reduced energy consumption, simplified control, and faster and more aggressive learning.
VIACTORS (2009-2012) Role: IIT Principal Investigaror
VIACTORS addresses the development and use of safe, energy-efficient and highly dynamic variable impedance actuation systems which will permit the embodiment of natural characteristics found in biological systems into the structures of the new generation of mechatronic systems. The results of this project will deeply impact applications where successful task completion requires people and robots to collaborate directly in a shared workspace or robots to move autonomously and as efficiently as humans.
ROBOTCUB (2004-2009)
ROBOTCUB was a research initiative dedicated to the realization of embodied cognitive systems and the creation of an advanced robotic platform for neuroscientific study. The two main goals of this project are; the creation of an open hardware/software humanoid robotic platform (iCub) for research in embodied cognition and the advancing of our neural understanding of cognitive systems by exploiting this platform in the study of the development of cognitive capabilities in humanoid robots.
