Download Maintaining Communications Link For A Robot Operating In A Hazardous Environment books, We address the problem of maintaining a robust high-bandwidth RF communication link between a mobile robot and its remote control/monitoring station. The solution we are exploring uses a number of autonomous mobile relay nodes. These slave robots convoy behind the teleoperated or autonomous lead robot and automatically stop where needed to maintain an ad hoc network that guarantees a link between the lead robot and its control station. their mobility allows for more versatility in the network. Nodes that are no longer needed in the network have the ability to navigate back to the lead robot, in order to redeploy at a later time. This further extends the lead robot's range. This paper describes the system, strategy, hardware development, software algorithms, and experiments conducted.

Download Maintaining Communication Link For A Robot Operating In A Hazardous Environment books, Communication is usually the limiting factor governing human-robot interaction during teleoperated operation in nuclear storage facilities. Thick concrete shielding makes it extremely difficult to maintain high- bandwidth radio communication. The same problem is encountered in urban law-enforcement applications and in hostile military operations. Hard cable tethers are cumbersome, require large spools for extended range, and are not appropriate for most applications besides urban explosive-ordnance-disposal. Thinner optical fibers, even reinforced, have been found to be fragile in field use in the Afghanistan and Iraq theaters. The cables often get run over by the robot as it is maneuvered around obstacles. Snagging and stretching of the fiber around corners often cause signal loss. These problems may be mitigated if the robot can assume some of the lower-level functions, such as obstacle avoidance and local path planning. This would reduce the amount of data traffic, and allow for the use of lower-frequency, lower-bandwidth radio links that have better wall penetrating capability. However, we have found that in critical missions, the soldier/operators preferred complete control of every aspect of the robot, minimizing any chance for surprises. Thus a high-bandwidth (video rate) communication link is required.

Maintaining Communications Link For A Robot Operating In A Hazardous Environment by Honghai Liu, Intelligent Robotics And Applications Books available in PDF, EPUB, Mobi Format. Download Intelligent Robotics And Applications books, The market demand for skills, knowledge and adaptability have positioned robotics to be an important field in both engineering and science. One of the most highly visible applications of robotics has been the robotic automation of many industrial tasks in factories. In the future, a new era will come in which we will see a greater success for robotics in non-industrial environments. In order to anticipate a wider deployment of intelligent and autonomous robots for tasks such as manufacturing, healthcare, ent- tainment, search and rescue, surveillance, exploration, and security missions, it is essential to push the frontier of robotics into a new dimension, one in which motion and intelligence play equally important roles. The 2010 International Conference on Intelligent Robotics and Applications (ICIRA 2010) was held in Shanghai, China, November 10–12, 2010. The theme of the c- ference was “Robotics Harmonizing Life,” a theme that reflects the ever-growing interest in research, development and applications in the dynamic and exciting areas of intelligent robotics. These volumes of Springer’s Lecture Notes in Artificial Intel- gence and Lecture Notes in Computer Science contain 140 high-quality papers, which were selected at least for the papers in general sessions, with a 62% acceptance rate Traditionally, ICIRA 2010 holds a series of plenary talks, and we were fortunate to have two such keynote speakers who shared their expertise with us in diverse topic areas spanning the rang of intelligent robotics and application activities.

Maintaining Communications Link For A Robot Operating In A Hazardous Environment by Rodrigues, João, Handbook Of Research On Human Computer Interfaces Developments And Applications Books available in PDF, EPUB, Mobi Format. Download Handbook Of Research On Human Computer Interfaces Developments And Applications books, Human Computer Interaction (HCI) is easy to define yet difficult to predict. Encompassing the management, study, planning, and design of the ways in which users interact with computers, this field has evolved from using punch cards to force touch in a matter of decades. What was once considered science fiction is now ubiquitous. The future of HCI is mercurial, yet predictions point to the effortless use of high-functioning services. The Handbook of Research on Human-Computer Interfaces, Developments, and Applications is primarily concerned with emerging research regarding gesture interaction, augmented reality, and assistive technologies and their place within HCI. From gaming to rehabilitation systems, these new technologies share the need to interface with humans, and as computers become thoroughly integrated into everyday life, so does the necessity of HCI research. This handbook of research benefits the research needs of programmers, developers, students and educators in computer science, and researchers.

Output Synchronization For Teleoperation Of Robot Manipulators

Maintaining Communications Link For A Robot Operating In A Hazardous Environment by Patrick Miller, Output Synchronization For Teleoperation Of Robot Manipulators Books available in PDF, EPUB, Mobi Format. Download Output Synchronization For Teleoperation Of Robot Manipulators books, With the emergence of innumerable unmanned robotic systems, there is a greater push for a robust and stable means of teleoperated control. Teleoperation is extremely useful in two major ways. First, a remotely control robot may be able to enter an environment which is dangerous or inhabitable by a human operator. This scenario pertains to autonomous vehicle or hazardous waste management applications. Secondly, robot manipulators are capable of detecting and compensating for environmental interactions and making more precise and consistent movements then their human counterparts. This becomes particularly useful robot assisted surgery. In such remote control applications, it is also important to accurately reflect the remote environment back to the human user. This is typically achieved by adding force and torque sensors on the remote system and transmitting force data back to the operator.^This is an ideal form of bilateral control since the sense of touch is significantly more sensitive then the human eye. However, problems arise when transmission delays are introduced into the link between host and remote system. Transmission delays are an unavoidable part of remote communications which are typically compensated by adding physical or virtual compliance into the system. However, this has the deleterious effect on 'transparent' perception of the remote environment. Thus, it is the responsibility of the control algorithm to compensate for delay induced instability while providing a transparent feel to the human operator. Maintaining the stability of the overall teleoperation scheme at a minimal loss of performance is the basis of this thesis. The case-study of telemanipulation of an RR planar manipulator and wheeled mobile robot using the stylus endpoint Phantom Omni haptic device will serve to form our efforts in this thesis.^First and foremost the devices are kinematically and dynamically dissimilar. These couple with the remaining issues of stable teleoperation over lossy, band limited, imperfect communication media to make this a challenging task. To this end we will study the application of a bilateral teleoperation framework developed [1] using nonlinear control and energy based stability theory to overcome some of the limitations. Locally an adaptive controller will identify and stabilize the dynamics of the master and slave systems. This local controller will rendered the dynamics passive to a secondary coupling input. A passive mapping is used to couple the output states of the master and slave systems. This mapping is shown to be insensitive to lossy and delayed communication mediums. A battery of simulations and real time experiments are used to verify the proposed controller.
