Paper Abstract

For several years various companies have been developing voice recognition software. Yet, there are few applications of voice control in the robotics field and virtually no examples of voice controlled three dimensional (3-D) systems. In late 1987 ARD developed a highly specialized, voice controlled 3-D vision system for use in remotely controlled, non-tethered robotic applications. The system was designed as an operator's aid and incorporates features thought to be necessary or helpful in remotely maneuvering a vehicle. Foremost is the three dimensionality of the operator's console display. An image that provides normal depth perception cues over a range of depths greatly increases the ease with which an operator can drive a vehicle and investigate its environment. The availability of both vocal and manual control of all system functions allows the operator to guide the system according to his personal preferences. The camera platform can be panned +/-178 degrees and tilted +/-30 degrees for a full range of view of the vehicle's environment. The cameras can be zoomed and focused for close inspection of distant objects, while retaining substantial stereo effect by increasing the separation between the cameras. There is a ranging and measurement function, implemented through a graphical cursor, which allows the operator to mark objects in a scene to determine their relative positions. This feature will be helpful in plotting a driving path. The image seen on the screen is overlaid with icons and digital readouts which provide information about the position of the camera platform, the range to the graphical cursor and the measurement results. The cursor's "range" is actually the distance from the cameras to the object on which the cursor is resting. Other such features are included in the system and described in subsequent sections of this paper.
