Inside the WIPP storage facility at the transitional dressing area prior to the boundary between "clean" and "unclean" areas.
U.S. DOE WIPP Site
Mock-up of the Exhaust Shaft Inspection by Dexterous Hexrotor at the DOE WIPP SiteDr. Richard Voyles, Collaborative Robotics Lab, Purdue University
• Nuclear waste storage facility in Carlsbad, New Mexico, USA,
• Deep geological repository licensed to permanently dispose of transuranic radioactive waste
• Radioactive waste packed in individual storage containers.
• Energetic incident occurred on Feb. 14, 2014.
• Demos with Dave Cappelleri (ME), Shoushuai Mou (AAE), Howie Choset (CMU)

Spatial layout of the U.S. DOE WIPP site indicating surface buildings with four shafts connecting the main work surface 660 meters below
ground. (reprinted from www.wipp.energy.gov)
WIPP: Structure
• Sub-surface storage facility in deep salt deposits approximately 660 meters (2150 feet) below the surface.
• Radioactive waste is packed in individual storage containers and lowered by elevator to "panels“
• An improperly loaded container experienced a chemical reaction and burst, spewing radioactive smoke through a large area of the WIPP

Definition of Frames
Earth Frame: Cylindrical coordinates
Body Frame: Cartesian coordinates ( x, y )
• Pilot gives targets coordinates in earth frame
• Transform targets coordinates to Cartesian coordinates in body frame
• UAV always keeps its heading along shaft radius, toward shaft surface
• Simplified fit of LIDAR points to a circle on sample of data points
• Pressure fused with small number of vidual data points for altitude
