13 2007 Haughton Crater Field Test 10 July – 3 August 2007Systematic site survey with two K10 robots3D scanning lidar for topographic mappingGround-penetrating radar for resource prospectingMultiple lunar analog sites at Haughton CraterRemote (habitat and ground control) robot operationsHaughton Crater(Devon Island, Canada)K10This field test is designed to examine: (1) multi-robot site survey, (2) IVA operations from a simulated habitat (Haughton-Mars Project base camp), (3) simulated ground operations (JSC Code ER “cockpit”) that is fundamentally different from MER (command-cycle based goal-directed traverses).Note: We are studying SURVEY OPERATIONS and ROBOTIC SOFTWARE. We are NOT testing robot mechatronics, nor locomotion performance. We use K10 robots (MER-class) because they are mature research systems that are well suited for terrestrial analog environments. Robotic site survey on the moon will LIKELY be performed with larger vehicles (e.g., a human-sized rover teleoperated from ground), but COULD be performed with MER-class robots (for more difficult terrain, permanently shadowed areas, far away from outpost).
14 Remote Operations “Pressurized Rover” ARC JSC “Lunar Outpost” NASA ARCNASA JSCDuring the test, two types of remote operations were conducted: (1) “Hab Ops”: shirtsleeved IVA from a lunar outpost (Haughton-Mars Project base camp) and a mobile habitat (a HMMWV) with no delay, high-bandwidth (54 Mb/sec) data networking, and (2) “Ground Control” at ARC and JSC (data carried by CSA satellite from Haughton to Toronto ground station, and then by Internet to ARC and JSC) with variable delay and lower (1 Mb/sec) bandwidth.“Pressurized Rover”ARCJSC“Lunar Outpost”Ground OpsIVA Ops
15 “Drill Hill” Survey 700 m Survey plan K10 robot on-site for 3 days One survey is of the “Drill Hill” region (location of previous ASTEP funded Mars drilling work), which is approximately 5km from base camp and requires a communications relay (provided by a HMMWV acting as a simulated pressurized rover). The surveyed region measures 700x700.This survey simulates lunar resource prospecting operations. GPR is one of two sensors (neutron spectrometer is the other) that is necessary for ground-truthing of buried water ice lateral and vertical distribution.Survey planK10 robot on-site for 3 daysHMMWV simulates pressurized rover (temporary habitat)Resource prospecting: subsurface ground-penetrating radar scans (parallel transects with 50 m spacing)
