Abstract

Imagine trying to navigate through your environment while looking straight ahead through a narrow tube. These are essentially the conditions the operator of an ROV in teleoperation mode may have to contend with. We hypothesized that controlling ground-based ROVs would be easier if an operator developed an explicit overview of the space in which the ROV was maneuvering. Accordingly, we conducted a study in which we had naive undergraduate participants explore a maze-like virtual desert environment while drawing a map of the area. After completing a 30-min mapping task, participants re-entered the maze to search for and retrieve a target object. The virtual robots and landscape, which had minimal landmarks and a maze of navigable paths (see Fig. 1), were created using CeeBot (see Chadwick, Gillan, Simon, & Pazuchanics, 2004, for a discussion of the CeeBot tool). Maps drawn by participants were rated independently by three raters (graduate psychology students) for the usefulness of the map for navigating the area on a scale from 1 (not at all useful) to 7 (extremely useful). Cronbach's alpha was computed as a consistency estimate of inter-rater reliability at 0.96.

Abstract

SA has been described as “generating purposeful behavior.” that is, behavior that is directed toward a task goal (Smith & Hancock, 1995). It involves being aware of what is happening around you and understanding what occurring events mean with respect to your current and future goals. Endsley (1995) has formally defined SA as the “perception of elements in the environment within a volume of time and space, the comprehension of their meaning and the projection of their status in the near future” (Endsley, 1995, p. 36). SA has been hypothesized as being critical to operator task performance in complex and dynamic operations (Salas, Prince, Barker, & Shrestha, 1995), like tasking and controlling remotely operated systems. Operators in remote control of ground vehicles need to be aware of where the vehicle is, what the vehicle is doing, and how activities as part of the overall task lead to accomplishment of mission goals. They must also consider the health of the overall system and how the environment affects vehicle status and the ability to complete tasks. In studying robot control in simulated USAR operations, Drury, Scholtz, and Yanco (2003) observed that most of the problems encountered when navigating robots resulted from the human's lack of awareness of these elements.

Abstract

When we take a top-down approach to understanding issues surrounding ROV implementation, we can employ the metaphor either literally or as a form of abstraction hierarchy (Rasmussen, 1986). Literally, the military's necessity for moment-to-moment information mandates a suite of context-specific technological capabilities for sensor and effector systems. This suite includes but is not limited to systems in outer space (such as geo-synchronized orbiting platforms), high altitude atmospheric systems (such as Global Hawk) and other craft which operate less than hundreds of feet from earth down to almost ground level itself.

Abstract

The goal of our initial study was to assess the usability of the prototype OCU and establish associated training issues. Seven participants completed self-paced training, guided by a training manual produced by ARI. Training was divided into three modules: (1) introduction and autonomous control, (2) manual control, and (3) creating and editing autonomous missions. Primary focus was on how to use the OCU to fly the MAV. Modules did not include elements such as fueling, setup, or tactics. A facilitator was present at all times to observe user interaction with the system and to manage the software. Data captured included time to complete each training module and related practical exercises, user feedback on questionnaires, and a written test on training content. Participants had either graduate-level experience in human factors psychology, prior military experience, or both. They were, therefore, able to provide valuable insights while they learned to operate the simulated MAV.

Abstract

The ROV ground control simulator (Fig. 1) used in this multi-sensory research consists of two workstations: pilot and SO. At the left workstation, the pilot controls ROV flight (via stick-and-throttle inputs as well as invoking auto-holds), manages subsystems, and handles external communications. From the right workstation, the SO is responsible for locating and identifying points of interest on the ground by controlling cameras mounted on the ROV. Each station has an upper and a head-level 17″ color CRT display, as well as two 10″ head-down color displays. The upper CRT of both stations displays a ‘God's Eye’ area map (fixed, north up) with overlaid symbology identifying current ROV location, flight waypoints, and current sensor footprint. The head-level CRT (i.e., “camera display”) displays simulated video imagery from cameras mounted on the ROV. Head-up display (HUD) symbology is overlaid on the pilot's camera display and sensor specific data are overlaid on the SO's camera display. The head-down displays present subsystem and communication information as well as command menus. The simulation is hosted on four dual-Pentium PCs. The control sticks are from Measurement Systems Inc. and the throttle assemblies were manufactured in-house.
