Abstract
Investigators discuss new findings in robotics. According to news originating from Urbana, Illinois, by NewsRx editors, the research stated, “This article explores the implementation of high-accuracy GPS-denied ad hoc localization.” Our news editors obtained a quote from the research from University of Illinois Urbana-Champaign: “Little research exists on ad hoc ultra-wideband-enabled localization systems with mobile and stationary nodes. This work aims to demonstrate the localization of bicycle-modeled robots in a non-static environment through a mesh network of mobile, stationary robots, and ultra-wideband sensors. The non-static environment adds a layer of complexity when actors can enter and exit the node’s field of view. The method starts with an initial localization step where each unmanned ground vehicle (UGV) uses the surrounding, available anchors to derive an initial local or, if possible, global position estimate. The initial localization uses a simplified implementation of the iterative multi-iteration ad hoc localization system (AHLos). This estimate was refined using an unscented Kalman filter (UKF) following a constant turn rate and velocity magnitude model (CTRV).”
