Service robots are machines designed to work not only for human beings (like the industrial robot) but also with human beings. In addition to challenging technical problems, the application of service robots in real-life situations requires to address intriguing issues concerning their interactions with humans. We are investigating both types of problems with reference to three different case studies and real research projects: a mobile robot system primarily aimed at the assistance of patients in hospitals and institutions (the ''URMAD'' project);a mobile robot system for the assistance to the disabled and the elderly at home (the ''MOVAID'' project);and a wheelchair incorporating a robot arm (the ''IMMEDIATE'' project). The paper discusses the design of the three robotic systems as well as their practical implementation and preliminary experimental results. Finally, the paper addresses recent results which could lead to the implementation of cybernetic prostheses, that is devices which would ultimately allow to achieve real intimate physical symbiosis between human beings and artificial robotic devices.

The developed airborne ultrasonic ranging systems employ digital-signal-processing techniques in the attempt to perform digital time-of-flight measurements using correlation methods. The main emphasis in this paper is given to the description of the technical solutions we have adopted in an effort to drive the system complexity down. Bandwidth sampling and digital interpolation techniques are proposed to perform the coherent demodulation of the narrowband received signals to baseband, so as to reduce the overall time complexity involved in computing the correlation functions. Via standard analog multiplexing techniques a sampling frame is defined to manage a number of transducers through a single, relatively slow analog-to-digital converter. Two versions of tracking sonar devices endowed with one transmitting transducer and four receiving transducers for operation at either high or low ultrasonic frequencies are illustrated.

The authors describe their approach to the design of redundant proximity sensor systems that are capable of extracting geometrical information about the surrounding environment and perceiving other relevant features of the reflecting objects, e.g. colour. Potential applications of the proposed sensorial systems are in the field of robotics and autonomous mobility.
This paper describes a sensor-based robot control method for handling non contact to contacttransitions in partially unknown environment. The proposed approach is based on the integration of proximity and force/torque...
