This paper describes the use of a low level, computationally inexpensive motion detector to initiate a higher level motion tracker based on an elliptical active contour or snake. The contour tracker is in turn used to direct a camera mounted on a robot arm. to track head shaped objects.

Pervasive and ambient intelligence will involve interaction coordination and cooperation among more and more smart devices. Research in Multi-agent systems addresses the issues of interaction and autonomy and thus provides interesting technologies to design pervasive and ambient computing environments. In this article, we explore various approaches to interconnect the physical and material worl...

This paper uses the kinematic mapping into the image space of spherical displacements to design a cooperating spherical robot system for workpiece orientating. The kinematic chain formed b y the cooperating robots grasping the workpiece forms a multi degree of freedom closed chain which is also known as a robotic mechanism. The spherical robots considered are spherical RPR open chains and they ...
