With the advantages of small size and low cost RSSI-based ranging and positioning technology is suitable for the large-scale applications or indoor environments. Whereas multipath structure of indoor radio channel caused by complex indoor environment, as well as the far field conditions of antennas are not feasible due to the short propagation distance, have a strong impact on indoor positioning accuracy...
Nowadays the Robotic Ubiquitous Cognitive network (RUBICON) has raised great attentions in robotics area. In this paper we explore and first propose a timely identification method of RUBICON with erasure channels. Firstly, the complex cognitive network is simplified into a single close-loop communicating network for identification. Then inspired by the interactive cognitive method, we propose recursive...
Many mobile robots especially tracked robots have been developed and used in disaster sites, however, few robots can really work in a nuclear accident. This paper presents a procedure of making a robot for nuclear accidents. Concepts and calculations before designing the robot are introduced, then Autodesk Inventor is used for designing the 3D model, Recurdyn is used for the dynamic simulation. After...
This paper addresses the visual servo control problem of a nano-scale quadcopter with a monocular onboard camera. The total weight of the helicopter with the camera is 48 g, and the helicopter belongs to a class of nano-scale aerial vehicles. The camera is a wireless device, and it is installed beneath the helicopter. The camera looks downward, and it captures an image of the ground at each time step...
The field of micro-robotics has made enormous progress in recent years. The progress in micro- and nano-technologies have enabled the micro-electro-mechanical systems (MEMS) actuators and sensors. A developing field has recently appeared in the nano- and micro- technologies, the untethered, micro-robots, which present potential applications in diagnosis and targeted drug delivery, implantation of...
Graphical modeling for System of Systems (SoS) permits defining supervision strategies for fault detection and reconfiguration of component systems to achieve a common task. Hypergraphs are being used to model the structural organization of an SoS at macroscopic level without being able to relate the whole system organization to element failure within a component systems at microscopic level. In our...
