A Novel Grey-RSS Navigation System Design for Mobile Robots
International Journal of Automation and Smart Technology, 2012 The active magnetic bearing (AMB) offers several advantages such as having no friction, high rotational speed, less energy loss, and long life span. In rotation application, however, it must be connected to a motor which may degrade its performance.
