Crawling movement as a motive mode seen in nature of some animals such as snakes possesses a specific syntactic and dynamic analysis. Serpentine robot designed by inspiration from nature and snakes crawling motion, is regarded as a crawling robot. In this article, a serpentine robot with spiral motion model will be analyzed. The purpose of this analysis is to calculate the vertical and tangential forces along snakes body and to determine the parameters affecting on these forces.
Todays typical volcanic data-collection station consists of a group of bulky, heavy, power-hungry components that are difficult to move and require car batteries for power. Remote deployments often require vehicle or helicopter assistance for equipment installation and maintenance. Local storage is also a limiting factor stations typically log data to a Compact Flash card or hard drive, which researchers must periodically retrieve, requiring them to regularly return to each station.
Power Line Communication (PLC) refers to provisioning of communication services over the electricity power grid. The main characteristics of PLC involves sending high frequencies using a PLC Carrier unit over power lines and injecting the frequencies (or picking them up) via a coupler linked directly to the power grid.
