The seed of the value chain of the Robotics, Brain and Cognitive Science unit (RBCS) is a “brain centric” approach to interaction science along three main streams of research: 1) humanoid robotics with a focus on cognition; 2) human behavioural studies and rehabilitation with a focus on action and perception, 3) human-machine communication and interaction with a focus on agent-agent cooperation guided by mutual understanding. A factor, common to all three streams is the focus on learning and development and, in general, on the dynamics of knowledge acquisition and update in the framework of goal directed actions.
The scientific value is generated by advancing knowledge of ourselves through the investigation of human motor, perceptual and cognitive abilities and the implementation of explanatory embodied models of such abilities. The technological value is produced from scientific results by developing new devices and technologies in three main areas: i) Hardware and software for machine intelligence; ii) Tools for quantitative evaluation of human performance in healthy and disabled persons; iii) Sensory and motor rehabilitation tools and protocols. The social value is produced by exploiting supportive and rehabilitation technologies to improve social inclusion and the quality of life particularly of the weak components of our society. A network of formalized collaborations and joint labs established with clinical and rehabilitation centres validates this value chain.
RBCS Unit embodies the concept of interdisciplinary by hosting and nurturing collaborations between scientists with very diversified background sharing an interest in producing these scientific, technological and social values.
Following this methodology, the fil-rouge of RBCS research has continued to be “action execution and understanding” with a focus on interaction science and a technological push toward rehabilitation devices for social use. Through interaction science we are investigating how humans and robots exchange information with the animate and inanimate world through contacts, speech and gestures.
RBCS scientists share a research infrastructure supporting psychophysical, behavioural and neurophysiological research based on experimental set-up including devices for motion tracking with force platforms, equipment for transcranial magnetic stimulation and electrophysiological recording (EEG and EMG). A full-fledged iCub humanoid robot is available for Cognitive Robotics experiments and human-robot interaction studies. Ad hoc experimental set-ups and protocols, as well as rehabilitation devices are developed by the mechanical and electronic facilities. Clinical studies and validation of rehabilitation protocols are carried out within several joint labs established in clinical and rehabilitation centres and through national and international collaborations.
The research activity is articulated in four streams of research:
The MLARR group focuses on Robotics and Interaction Technologies for Neuroscience and Neurorehabilitation. In particular, research is articulated as follows: 1) Developing cutting edge mechatronic and robotic technology to enhance/augment human robot interaction with a special focus on robot aided rehabilitation; 2) Studying the neural plasticity that underlies the organization of the human sensorimotor system in skill acquisition; 3) Integrating technology in the clinical/home environment developing new standards of assessment.

The scientific aim of the research of this group is to investigate the sensory and motor mechanisms underlying mutual understanding in human-human interaction, with the technological goal of designing robots that can naturally cooperate with people in carrying out everyday tasks. The peculiarity of our approach is that robots, rather than being just the final goal of the research, are used as the ideal tool to investigate social interaction in a principled way.

The research activity at the DTI is focused on the hand, the haptic perception of objects and haptic exploration of the environment, the control of finger forces in multi-finger grasp and, more generally, physical interaction with objects or person. The lab has developed various devices and setup based on robotic and haptic technology and has expertise in kinematic and dynamic analysis of movement, behavioural and psychophysical techniques, and the modelling of perceptual and decisional processes.

We investigate how sensory deprived individuals compensate missing sensory channels by vicarious modalities. Our focus is on sensory enhancement and how to achieve it with novel assistive technologies, mainly aimed at the construction of cognitive maps. Our methodology serves to build hardware/software platforms to decrease the digital divide, therefore increasing social inclusion. We focus on three main topics
Sensory Substitution: How much spatial knowledge depends on visual experience? We investigate the neural and behavioural correlates of tactile spatial representations.
Small Area Haptic Device: Are we able to understand simple tactile virtual objects? We study how information can be coded, displayed and understood by humans through low-tech haptic displays.
Sensory Supplementation: Is it possible to improve the spatial soundscape of hearing impaired individuals? We study how binaural acoustic feedback can be used in context where hearing loss prevents proper spatial awareness.
