Wireless communications are one of the technical problems that must be addressed by cooperative robot teams. The wireless medium often becomes heavily loaded and the robots may take too long to successfully transmit information, resulting in outdated shared data or failures in cooperative behaviors that require synchronization among teammates.

This paper describes the status of the SocRob MSL robotic soccer team as required by the RoboCup 2013 qualification procedures. The team’s latest scientific and technical developments, since its last participation in RoboCup MSL, include further advances in cooperative perception; novel communication methods for distributed robotics; progressive deployment(More)
This paper describes the status of the ISocRob MSL robotic soccer team as required by the RoboCup 2011 qualification procedures. The most relevant technical and scientifical developments carried out by the team, since its last participation in the RoboCup MSL competitions, are here detailed. These include cooperative localization, cooperative object(More)
Objective: To investigate growth asymmetry between the left and right hemimandibles (HMs) during the 2nd and early 3rd trimester of pregnancy. Methods: Sixty eight hemimandibles (34 mandibles) of fetuses were used—20 female and 14 male—preserved in 10% formalin solution, and the following measurements were performed: Condyle-Coronoid Process (Co-CP),(More)
– The robot’s vision system is based on an AVT Marlin F-033C firewire camera, which is equipped with a fisheye lens providing a field-of-view of 185◦, facing downwards. This dioptric system endows the robot with omnidirectional vision, capable of detecting relevant objects (such as the ball and other robots) at a distance of up to 5 m. This particular setup(More)
INTRODUCTION Laryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx and represents less than 2% of extrapulmonary TB cases. There are no pathognomonic clinical and endoscopic features of this disease and studies on LTB that can assist in its diagnostic characterization are lacking. OBJECTIVE To identify factors associated(More)
INTRODUCTION Laryngeal tuberculosis (LTB) is the most frequent larynx granulomatous disease. In general there is lung involvement, but in an important proportion of cases you can find LTB without pulmonary disease. The lesions observed in LTB, such as ulceration and fibrosis, can interfere in the process of voice production. The involvement of the mucous(More)
This demo paper serves to describe a research platform for autonomous surveillance by mobile robots. System components from various technical disciplines (including robot navigation, computer vision, discrete event systems, and human-computer interaction) have been combined together into a cohesive, modular system architecture. We employ our architecture to(More)
