About

Education 

I received the bachelor and master degrees in Control Engineering with highest honors from "Sapienza", University of Rome, in 2007 and 2009, respectively. I also received the "Academic Excellence Award" from Sapienza in 2009. In 2013, I received the PhD title in Information and Communication Technologies from University of Nice Sophia Antipolis, with a thesis prepared at INRIA Sophia Antipolis, France, under the supervision of Tarek Hamel, and Claude Samson. The PhD program was jointly with Sapienza, university of Rome, so I also received a PhD in Control Engineering from “Sapienza".

 

Current position

Since August 2017, I am a research scientist leading the Dynamic Interaction Control lab at IIT. Our research can be decomposed into three research axes: bipedal-locomotion, physical-human-robot-interaction, and aerial-humanoid-robotics. The young, dynamic, and highly motivated team is composed of twelve persons.

2015-2017, Senior postdoc, team leader of four PhD students  

From 2015 to August 2017 I have been a senior postdoc within the Dynamic Interaction Control Lab. I have beed coordinating four PhD students. 

Their domain of expertise is on planning, estimation, and control of floating base systems. Francesco Romano graduated in 2016, and is now a research engineer at Google DeepMind

2013-2015,  postdoc, in the coordination PI team of the CoDyCo project

From 2013 to 2015, I have been a  postdoc responsible for the experimental activities associated with the deliverables of CoDyCo, project number: 600716 FP7-ICT-2011.2.1 Cognitive Systems and Robotics. The project has been graded as excellent for four years. Given the success of the experimental activities obtained as an outocme of the project, I have been included in the coordination PI team of the project - see this video, minute 1:55 - coordinating a team of three PhD students.

Projects

The research activities of the Dynamic Interaction Control lab can be decomposed into several research axes

Bipedal-locomotion

The goal of this research axis is to endow the humanoid robot iCub with a degree of bipedal locomotion. Prior to locomotion, the balancing capability is a fundamental property that must be studied and implemented on the robot. This video below show the balancing capacity of iCub. While this video shows preliminary locomotion capabilities of the humanoid robot iCub.

 

 

Adaptive Control

Collocated adaptive control of underactuated mechanical systems is still a concern for the control community. The main difficulty comes from the nonlinearity of the collocated inverse dynamics with respect to the base parameters, which forbids the direct application of classical adaptive control schemes. Our work extends and encompasses the Slotine’s adaptive control, which was developed for fully actuated mechanical systems, to stabilize the collocated state space of an underactuated mechanical system. The key point is to define the sliding variable as the difference between the system’s velocity and an exogenous state whose dynamics is considered as control input. We have first revisited the Slotine’s result in view of this definition, and then showed how to extend it to the underactuated case. Stability and convergence of time varying reference trajectories for the collocated dynamics are shown to be in the sense of Lyapunov. Simulations, comparisons to existing control strategies, and experimental results on a two-link manipulator verify the soundness of the proposed approach.

Flight Dynamics

Feedback control of aerial vehicles in order to achieve some degree of autonomy remains an active research domain after decades of studies in the subject. The complexity of aerodynamic effects and the diversity of flying vehicles partly account for this continued interest. The scientific community has dealt with the control of flying machines by mainly developing different strategies in relation to different classes of aerial vehicles – as exemplified by airliners and helicopters – and no unified approach has been developed so far. My research attempt contributes towards the development of such a unified approach by taking into account nonlinear aerodynamic effects in the control design.

Mobile Wheeled Robots

Providing autonomous platforms that may improve the quality of our lives is an active research domain in robotics. Among these platforms, we studied the problem of a mobile robot that must follow a user. This robotic application can  be used for several tasks such as  shopping carts, butlers that may help for carrying heavy objects, or walking-aid systems. For such mobile platforms to work properly, two basic issues must be dealt with. The first one concerns the detection of the user and the estimation of its position with respect to the robot. The second issue is the design of feedback control laws that maintain a desired relative position between the robot and the user. I actively contributed to providing new solutions to these two issues. For instance, it is well known that position controllers typically used to stabilize the robot with respect to the user work well when the user is located in front of the robot and moves forward. In particular, the so-called jack-knife effect is problematic if the user starts moving backward. I proposed a solution that allows us to stabilize the robot w.r.t. the person with the latter located sideways – i.e. along the wheels’ axis – and also ensures jack-knife effect avoidance. It can be implemented with conventional sensor suite since the control law is position-based, i.e. the relative orientation of the person w.r.t. the robot is not needed to compute the control law.

Nuclear Fusion

Accurate chamber pre-fills and plasma density control are primary concerns when dealing with tokamak machines, and I contributed to developing a control strategy for these two concerns. Plasma density evolutions are governed by a set of partial differential equations involving machine’s geometries, electromagnetic fields, atomic physics, and initial conditions of the entire system. This set of equations cannot in general be written in the state-space representation, and this renders almost inapplicable most of the classical  control methods. We proposed to take a different route by considering a linear, autonomous, model for the so-called averaged line plasma density. Then,  the control designed was performed on this model by applying a nonlinear PID with a classical anti-wind up. The chamber pre-fill control is achieved analogously. The whole system has been implemented using the real-rime framework MARTe, coded in C++.

I numeri di IIT

L’Istituto Italiano di Tecnologia (IIT) è una fondazione di diritto privato - cfr. determinazione Corte dei Conti 23/2015 “IIT è una fondazione da inquadrare fra gli organismi di diritto pubblico con la scelta di un modello di organizzazione di diritto privato per rispondere all’esigenza di assicurare procedure più snelle nella selezione non solo nell’ambito nazionale dei collaboratori, scienziati e ricercatori ”.

IIT è sotto la vigilanza del Ministero dell'Istruzione, dell'Università e della Ricerca e del Ministero dell'Economia e delle Finanze ed è stato istituito con la Legge 326/2003. La Fondazione ha l'obiettivo di promuovere l'eccellenza nella ricerca di base e in quella applicata e di favorire lo sviluppo del sistema economico nazionale. La costruzione dei laboratori iniziata nel 2006 si è conclusa nel 2009.

Lo staff complessivo di IIT conta circa 1440 persone. L’area scientifica è rappresentata da circa l’85% del personale.

Out of 45% of researchers coming from abroad 29% are foreigners coming from more than 50 countries and 16% are returned Italians. The scientific staff currently consists of approximately 60 Principal Investigators110 researchers and technologists350 post-docs and 500 PhD students and grant holders and 130 technicians. External funding has allowed the creation of more than 330 positions . The average age is 34 and the gender balance proportion  is 41% female against 59% male.

In 2015 IIT received 96 million euros in public funding (accounting for 80% of its budget) and obtained 22 million euros in external funding (accounting for 20% of its budget).
