Human-Systems Integration • Device Control: sensors/ instruments, tools, robots, systems (life, power, computing) • Data Flow: Queue, sample, store, associate, share, display Voice-Commanded Toolkit • Work Management: Monitor, advise (loc, time, activity), interpret, alert WILLIAM J. CLANCEY, PI & MAARTEN SIERHUIS, PROJECT MANAGER
Technical Features • Multi-Agent System – Functional & personal – Distributed control & dataprocessing • Wireless Computing – Platform independent – Tested over 5 km • Modular Configurations – Plug & play (Java API) – E. g. , 5 robots, 3 cameras, 5 biosensors, 2 computer sensors, d. GPS, headsets Astronaut Backpack System
Mobile Agents Utah Field Test 2005 Geologists Exploring with Mobile Agents • 50 Participants; 17 days; 2 NASA centers & several universities • Multi-robot, auto-recon, & freeform exploration scenarios • More proactive ERA design • More proactive RST • More robust, faster, reusable agent system (> 60) • Improved alerts, queries (> 90), & auto-associations • EVA crew less reliant on Hab. Com crew member
New MA’ 05 Operations • Interacting with the robots to determine their status: Whom are you following? Do you still have comms? • Establish dependence on robot relay: Boudreaux, join me. • Contextual robot move commands: Come here. Go there. • Directed photos: Take a picture of work site 5. • Astronaut naming of “work stations" (default 1 m areas) within work sites: Call this location 9 with a radius of 5 m. • Astronauts can refer to names teammates create. • Requesting locations and navigation information: Where is work site 5? Where am I? List all the locations near work site 6. Where is the next activity?

Experiment Observations (Day 5 EVA 2 Beyond Pooh’s Corner) • Enables independent, simultaneous work, which geologists prefer • But agents talk over astro conversations – Astro cannot hear that partner is listening to agent – Astro interleaves response with conversation – Results in “What did you say? ” Overall: System Responsive and processed data appropriately • Ready for next level: Voice loop management, alternative feedback, protocol personalization
Example Good Results Where is Boudreaux? Boudreaux, stop. How much time is left? What is the current activity? (Astro 2) Where is Astronaut 1? Where am I? Warning: Time exceeded. Sorry: Can’t do that. Warning: Battery is low.
Some Not So Good Results Misunderstood “okay” as volume change command. Boudreaux is 1. 1794857 E 7 meters North-East from you. Thibodeaux, join me (OK) Astro 2 remarks to partner that join command worked; Astro 1 is listening to his agent and didn’t understand; Astro 2 repeats what she said, but agent hears this as the command itself!
