A Space Photographic Robotic Arm (SPRA) system for astronautical application is introduced in this paper. This system is designed for the taking photo task of some small size equipments in orbit in future. Considering of the system reliability, a 5-DOF movement platform is utilized to carry and drive the observed equipment to move and rotate in appointed directions so that the cameras of SPRA can...
Due to resource constraints, digital image transmissions are a significant challenge for image sensor based wireless sensor networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called image component transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Essential components such as the information for the positions of significant...
