The human operation and telerobotic and supervisory control of sophisticated and remote decontamination and decommissioning (D&D) robotic systems is a complex, tiring and non-intuitive activity. Since D&D and selective equipment removal (SER) are going to be a major future activity in DOE's ER&WM cleanup agenda, it seems appropriate to utilize an operator control station and interface which maximizes operator comfort and productivity. Carnegie Mellon University (CMU) proposes to develop a state-of-the-art robot operator control station with standard hardware and software control interfaces to be used on a variety of D&D robotic systems currently under development by the OTD. The purpose of this system is to provide a reconfigurable operator interface platform, applicable across D&D robot systems, allowing for cost-effective testing and deployment of various robot systems for demonstration and field-use purposes.The benefit is to be seen in the ability to control different robot systems through simple interchange of interface modules mounted to the operator's chair, and the porting/development of interface display software to a common computing and programming platform. Cost savings can be realized through this system, since it represents a powerful and re-configurable test platform for evaluating the various robot systems currently available or under development for the OTD D&D, Tanks and Mixed Waste focus groupsprograms. The proposed system consists of a large multi-screen projection-TV system framed on both sides by several high-resolution TV monitors, stereo speakers, a reconfigurable operator console and control chair module with various removable interface modules (such as joysticks, buttons, touch-screen, etc.), all ergonomically mounted on a raised platform and integrated with the display and control electronics. The embedded computing consists of computing racks to operate the consoles and to house the robot-control and interface computing. The console computing consists of a dedicated processor system operating communicating with other hardware and interfaces via NDDS over ethernet, serial or parallel interface. Adequate rack space is also provided for the integration of video recorders and other potential computing platforms such as SGIs. All hardware systems support the C-based programming environment for the re-programmable operator interfaces and displays. Compatibility with other DOE console and controller efforts will be enforced at the hardware (VME, VxWorks) and software level. The entire system is configured to optimize the information display and operational efficiency of a human operator controlling or supervising remote systems from the seated position to allow him/her to control the display configuration, live video links and graphical overlays and to input information using the hard-wired switches and the touch-screen display. The current configuration is targeted for use with the Houdini in-tank mobile cleanup robot at Fernald and ORNL, the Rosie mobile worksystem and the dual-arm manipulation system at the Oak Ridge National Laboratory (ORNL). The proposed development and integration will occur in a single 24-month phase, to demonstrate the basic display and computing and control chair systems at CMU on a pre-prototype version of Houdini by August 1997. The system, including all documentation and users manuals will be delivered to the International Union of Operating Engineers (IUOE) HQ in Beckley, WV for a subsequent demonstration and follow-on training by November 1997, thereby allowing them to control an automated Caterpillar D4 bulldozer.
