Williams and Robert Morris (guest lect.) 16.412J/6.834J March 2 nd , 2005 based on: “Application of Mapgen to MER,” by Kanna Rajan “Handling Time: Constraint-based Interval Planning,” by David E. Smith Outline Based on slides by Dave Smith, NASA Ames • Operational Planning for the Mars Exploration Rovers • Review of Least Commitment Planning • Constraint-based Interval Planning • Temporal Constraint Networks • Temporal Constraints with Preference Mars Exploration Rovers – Jan. 2004 - ?
