Cooperative robots are more efficient than a robot when the assigned task is complex and the workspace is large. To meet with the task efficiency and successful control of Cooperative robots, sensing and networking of the robot are necessities. To ensure stable communication, the cooperative routing robot system is implemented. Our system is an autonomous reactive router that responds to change in strength of a signal and a quality of link among cooperative robots. The routing robot is driven toward a safety region of network using virtual force model or change into a router. A result of our approach was shown as an experiment. A tank robot was continuously teleoperated from ROC (remote operate center);thereby condition of network was proven to be stable. In addition, the ROC continuously acquired a remote video and positions. As a result, the cooperative routing robot system help you teleoperate a robot about long distance. © 2012 Springer-Verlag Berlin Heidelberg.

As manufacturing systems become increasingly more automated and complicated, there is a need for supervision systems to operate and control production. In complex manufacturing environments, robots can make errors that can cause serious product damages. This paper focuses on the efficient supervision systems, called the sequential task-oriented supervision, using multiple sensors for achieving task status monitoring, automated error analysis in robotic manufacturing process. As with the designed task sequence, a status monitoring system runs synchronously to detect errors in the current robot task. In order to continue performing tasks without human intervention, task status monitoring systems use multiple sensors including a vision sensor, a force-torque(F/T) sensor and a tactile sensor is developed. Detailed structure and working principle of the monitoring system are addressed in this paper. © 2012 IEEE.

Alternative radio-navigation technologies aim at providing continuous navigation solution even if one cannot use GNSS (Global Navigation Satellite system). In shadowing region such as indoor environment, GNSS signal is no longer available and the alternative navigation system should be used together with GNSS to provide seamless positioning. For soldiers in battlefield where GNSS signal is jammed or in street battle, the alternative navigation system should work without positioning infrastructure. Moreover, the radio-navigation system should have scalability as well as high accuracy performance. This paper presents a TWR (Two-Way-Ranging)-based cooperative positioning system (CPS) that does not require location infrastructure. It is assumed that some members of CPS can obtain GNSS-based position and they are called mobile anchors. Other members unable to receive GNSS signal compute their position using TWR measurements with mobile anchors and neighboring members. Error propagation in CPS is analytically studied in this paper. Error budget for TWR measurements is modeled first. Next, location error propagation in CPS is derived in terms of range errors. To represent the location error propagation in the CPS, Location Error Propagation Indicator (LEPI) is proposed in this paper. Simulation results show that location error of tags in CPS is mainly influenced by the number of hops from anchors to the tag to be positioned as well as the network geometry of CPS. © ICROS 2015.

Component-based robot development has been a vibrant research topic in robotics due to its reusability and interoperability benefits. However, robot application developers using robot components must invest non-trivial amount of time and effort applying fault tolerance techniques into their robot applications. Despite the need for a common, framework-level fault management, the majority of existing robot software frameworks has failed to provide systematic fault management features. In this paper, we propose a fault management method to detect, diagnose, isolate and recover faults based on the OPRoS software framework. The proposed method provides a collective, framework-level management for commonly encountered robot software faults, thereby reducing the application developers' efforts while enhancing the robot system reliability. To verify the effectiveness of the proposed approach, we have implemented a prototype reconnaissance robot using OPRoS components and injected different types of faults. The results of the experiments have shown that our approach effectively detects, diagnoses, and recovers component faults using the software framework. © 2011 IEEE.

This paper provides stability conditions of an uncertain networked control system with both forward control signal loss and feedback output signal loss. It is assumed that both the forward control signal and the output measurement signal are intermittent independently, and the remote plant has a model uncertainty. Also, in this paper, an observer-based controller is used in the remote place because the full states are not accessible. Thus, the main research goal is to analyze the overall stability of this uncertain intermittent networked system. In the second part of this paper, we consider delay effects of both forward signal and feedback signal during the network transfer
