Abstract:
A system and method for relieving hang-ups, comprising a mobile command vehicle operative to transport a robotic vehicle to a control location remote from a hang-up location; the robotic vehicle operative to advance from the control location to the hang-up location, scan the hang-up location, transmit scanning information to the command vehicle, and receive positioning commands to position the robotic vehicle for drilling into the hang-up location, implant an explosive, and withdraw.
Abstract:
A telerobotic communications system including a teleoperation center to transmit control data and receive non-control data by wireless connection to and from a first mobile telerobot and indirectly to and from a second mobile telerobot. The first mobile telerobot includes a transceiver for receiving and transmitting control and non-control data, respectively, and also a repeater for relaying control data to a second mobile telerobot and relaying non-control data back to the teleoperation center. The system allows the second mobile telerobot to travel beyond a communications-enabled distance of the wireless signal emitted directly by the teleoperation center. The system may also include wireless repeaters to extend the communications distance between the first and second telerobots.
Abstract:
A system for monitoring movement in a subsurface environment, which may be used to determine flow dynamics within a fluid mass such as an ore body, or track subsurface persons or moving assets. A plurality of underground positioning system (UPS) elements in the subsurface environment transmit characteristic signals to a plurality of antennas, which transmit the signals to a data processing apparatus. The system thus determines changes in the positions of the UPS elements to derive an indication of the motion of the fluid mass or the locations and movement of subsurface persons or assets.

Abstract:
A wireless optical communication receiver is provided. The optical receiver includes an arrangement of wavelength shifting fibers preferably encased within a protective shroud. The wavelength shifting fibers provide an efficient method for capturing photons of light that strike them. Photons may strike the fibers as they first pass through a clear lens in the shroud or may strike the fibers after they are concentrated and focused by an embedded ring or hyperbolic mirror. The wireless optical receiver may be attached to a mobile vehicle in order to facilitate teleoperation of that vehicle.

Abstract:
An underwater optical communications system and method particularly suitable for use in communications with automated equipment. A series of light beacons are dispersed throughout a communications zone. The light beacons are each provided with a plurality of light-emitting elements and light receiving elements which are positioned so that each beacon within the communications zone emits light in a plurality of directions and receives light from a plurality of directions. A submersible craft is similarly provided with light emitting elements and light receiving elements. The submersible craft is thus always in optical communication with one or more beacons when in the communications zone, regardless of the orientation of the craft and regardless of the position of the craft within the communications zone.
Abstract:
A robotic mapping system for charting or mapping a path through an underground cavity, and/or mapping a surface of the underground cavity. The robotic mapping system may comprise a mobile control center located on the surface in wireless communications with one or more mapping robots located within the underground cavity. The mapping robots may be controlled by way of an avionics navigation system.
Abstract:
Provided is a telerobotic mining device for underground mining, and specifically for stope mining, as well as a method of mining using such a device. The telerobitic mining device is capable of remotely moving about a mine and utilizing drill arms to drill a hole within a chosen rock bed. Explosive placement arms on the telerobot may be utilized to place an explosive within the drilled hole to blast away rock. Control over the device is achieved by way of operational commands that may be wirelessly sent to the device from a command center located outside the mine.
