Reference # : Model No : 3D-ICAS

The Three-Dimensional Characterization and Archiving System (3D-ICAS) is a remote system that performs real-time in-situ analysis of hazardous organics and radionuclide contamination on structural materials. The 3D-ICAS system is composed of six main subsystems: I. Multisensor Probe (MSP): attached to the end of the robot arm, houses radionuclide sensors (RN), which detects and quantifies radiation levels; the sampling head for desorbing and collecting organic materials for quantitative analysis via high-speed gas chromatography with mass spectrometer (HSGCIMS); the X-ray fluorescence (XRF) Instrument for toxic metal and substrate identification; the molecular vibrational spectrometry (MVS) fiber optics for detecting and identifying inorganic materials, and proximity sensors for guiding the probe to a Imm standoff distance from the surface. 2. Integrated Workstation (IWOS): operated outside the contaminated area that the 3D-ICAS is examining and remotely controls the 3D-ICAS. 3. Contamination Analyzing Unit (CAU): extracts and analyzes the contaminated samples taken from the inspected area. 4. 3D Coherent Laser Radar (CLR): surveys the area to provide a spatial map of the facility and guides the robot arm with millimeter accuracy. 5. CRS Sensing Robot Arm Subsystem (SRAS): conveys the MSP to the desired position for making contaminant measurements. 6. Survey Archive Database (SADB): contains a complete record of spatial and contaminant data and provides capability to display contaminant data overlaid on a physical map of the surveyed facility with hyperlinks to detailed sensor measurement data. All subsystems are integrated onto a single vehicle, which is operated on electrical batteries. Operational procedures consist of placing the equipment In the area to be surveyed, activating the mapper to obtain a topological map of the facility, selecting locations to be surveyed, and initiating the survey. The operator, who may be located remotely in a safe environment, merely specifies the area to be mapped. Otherwise, the system operates autonomously and unattended, although the operator may monitor the progress of the survey and intervene if necessary. Mapping, survey, and analytical results are automatically saved in the computer and may be retrieved afler the job is completed.

Benefits

1.CLR mapping and calibration of the location system using a trihedral and three steel spheres attached to a frame with x. y, and z arms, 2. The motion response of the robotic arm to the laser-assisted (by pinpointing laser) commands. 3.The entire sampling schedule that coordinates the sampling sequence: organics, heavy metals, and radionuclides.

Limitations

Not limitation was overcoming during the demonstration
