Robots in swarms take advantage of localization infrastructure, such as a motion capture system or global positioning (GPS) sensors to obtain their position, which can then be communicated other robots for swarm coordination. However, the availability infrastructure needs not guaranteed, e.g., GPS-denied environments. Likewise, communication overhead associated with broadcasting locations may u...

Radio frequency identification (RFID) technology attracts extensive attention for industrial applications, especially supply chain businesses and inventory management. In this article, a passive RFID localization scheme based on unmanned aerial vehicles (UAVs) or drones is established management in warehouses. case of the major challenge on-board antenna tracking errors practical scenarios, sta...

Mutual localization provides a consensus of reference frame as an essential basis for cooperation in multi-robot systems. Previous works have developed certifiable and robust solvers relative transformation estimation between each pair robots. However, recovering poses robotic swarm with partially mutual observations is still unexploited problem. In this letter, we present complete algorithm it...

wireless sensor networks attracting a great deal of research interest. accurate localization of sensor nodes is a strong requirement in a wide area of applications. in recent years, several techniques have been proposed for localization in wireless sensor networks. in this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

background although neuregulin-1 （nrg1）and its receptors have been indicated at the mrna level in partial human endocrine organs and its functional roles have been evaluated in vitro, their morphological distribution in higher animals are not fully studied. the present research focused on expression of nrg1 and its main receptors erbb2 and erbb4 in main endocrine organs of the rhesus monkey. ma...

We present a relative localization method based on sound source localization for mobile robots in outdoor environments. One robot estimates the relative position of nearby robots by receiving the sound signals they generate. In our work, a device including a buzzer and an array of four microphones is designed and installed on each mobile robot. We describe a technique for calculating the relati...

The localization of objects equipped with passive UHF RFID labels using the Received Signal Strength Indicator (RSSI) values is investigated. An Unscented Kalman Filter (UKF) is used for the localization of the object. Adding (N-1) additional tags with known relative position to the object (relative to its main tag), this information can be incorporated into the UKF resulting in an Unscented Ka...
