  1. NASA Remote Agent WPI CS534 Showcase Jeff Martin

  2. Computer Software on Deep Space 1 • Used to execute plans/mission objectives • Model based • Constraint based • Fault tolerant What is it?[1]

  3. Remote agent was a result of the New Millennium Program • This program was established to test technologies that would be used in Space [1] • Remote Agent was created from the join effort from [2]: • NASA's Ames Research Center • JPL (Cal Tech's Jet Propulsion Labratory • Was First tested on NewMaap [2] • New Millennium Autonomous Architecture Rapid Prototype • First Version was developed in 5 months. • Its goals where to plan and execute entry through Saturn's Rings and define an orbit • Was field tested on DS1 [3] History

  4. To perform decisions on a space craft without interaction from ground controllers • Will allow faster response time to environment conditions • To be used when communication to ground control is not possible Remote Agents Goal[1]

  5. RA Communication Architecture[1]

  6. "Planner/Scheduler” • Execution component: called "Smart Executive” • "Mode Identification and Recovery (MIR)" Main components of RA

  7. Database of mission objectives(goals) • Creates Plans for mission objectives for next timeline • Define the operations (activities) that are needed to meet the objectives • Ex: while one operation is performed another cannot be • New Plan requests • Normal conditions • Requests new plan based on horizon • Fault conditions • Requests new plan if detected issue will effect future execution • Decisions made based on potential outcomes • Running more equipment then available power Planner/Scheduler

  8. Makes initial request for a plan • executes operations that meet the objectives from the plan devised by the planner • Space craft component operations • Makes decisions on what to do in the event the outcome is not successful • taking a picture of an object • Attempts to recover (Retry, recovery from MIR, await replanning) Smart Executive

  9. Smart Executive Planning Cycle[1]

  10. Mode Identification and recovery • Monitors state of the systems on the Spacecraft • receives sensor data • compares to expected model • Recognizes problems • Requests actions to correct to Smart Executive • Reports Failures to Smart Executive MIR

  11. MIR Flow[1]

  12. The FAQ Site says no [1] • MEDIA Relations press release say "the first artificial Intelligence software in history to command a spacecraft" [2] • It is expected to handle situations that are unexpected, given current circumstances Is Remote Agent Intelligent?
