By far the largest food assistance program in the United States, SNAP‟s central goal is to alleviate food insecurity. In this light, policymakers have been p...

During the last years, a new field has attracted the interest of robotic researchers. Minimally invasive techniques, such as laparoscopy, have grown as a very suitable domain for robotic systems. In this field, one of the easiest application for robotics is the movement of the endoscopic camera. That kind of robots [7][6] aims to move the camera from outside the patient’s abdomen to get the ima...

Space robotics will become a key technology for the exploration of outer space and the operation and maintenance of space stations, satellites and other platforms, saving costs and relieving man from dangerous tasks. But we do not have to wait until robots are really autonomous or intelligent, since by modern tele-operation and tele-presence we are able to remotely control robot systems from th...
