Correct diagnosis under harsh environmental conditions is crucial for space vehicles’ health management systems to avoid possible hazardous situations. Consequently, the diagnosis methods are required to be robust toward these conditions. Design of a parametric fault detector, where the fault estimation is formulated in the so-called standard set-up for H∞ control design problem, is addressed i...
Taking a broader perspective than the conventional field of teleoperation and telerobotics, this paper proposes the concept of human robot synergism, as a practical approach to carrying out a variety of “intelligent” manipulation tasks whose procedures and environment may not be well anticipated beforehand. Such a human robot synergetic system would be essential not only for transferring human ...
Ubiquitous computing is giving rise to applications that interact very closely with activity in the real world, usually involving instrumentation of environments. In contrast, we propose Cooperative Artefacts that are able to cooperatively assess their situation in the world, without need for supporting infrastructure in the environment. The Cooperative Artefact concept is based on embedded dom...
Inherent dangers in mining operations motivate the use of robotic technology for addressing hazardous situations that prevent human access. In the context of this case study, we examine the application of a robotic tool for map verification and void profiling in abandoned limestone mines for analysis of cavity extent. To achieve this end, our device enables remote, highly accurate measurements ...
Recent man-made or physical disasters, such as the Deepwater Horizon oil spill and the Fukushima Dai-ichi nuclear crisis, have highlighted the enormous potential of robots capable to perform hazardous activities during disaster response operations1, resulting in a growing interest in Urban Search And Rescue (USAR) robotic research worldwide. In this context, initiatives such as the DARPA Roboti...
Simple expert systems are presented that will allow more people to use powered wheelchairs. The systems interpret hand tremor and provide joystick position signals. Signals are mixed with ultrasonic sensor data to identify potentially hazardous situations and assist users to find a safe course. Results are discussed from a series of timed tasks completed by users using a joystick. They suggest ...
The remote control of vehicles, typically useful in hazardous situations, is a difficult and skilled task. Users experience great difficulty in performing relatively simple operations, such as avoiding obstacles and maintaining control of the device. This contrasts strongly with high user performance when controlling a local vehicle. We suggest that one reason for this is the absence of haptic ...
Safety applications provided by Vehicular Ad Hoc Network is very crucial. The vehicles in the road form a network enabling the passengers with infotainment and security. Emergency messages can be disseminated in the VANET scenario for securing the lives of people by avoiding the situations like chain collisions. The main aim of such messages is to provide safety. So these messages should be gen...
