Plan Execution Engine
Real-Time Plan Execution and Monitoring System
Engine executing planned actions while monitoring for deviations and triggering replanning
Purpose
Engine executing planned actions while monitoring for deviations and triggering replanning
Context
Child of L2-CDH-AUTO
Principles
- ▸Execution monitoring compares actual vs expected outcomes at each plan step
- ▸Exception handling triggers replanning when execution deviates from plan
- ▸Resource tracking ensures actions don't exceed available power, time, or materials
- ▸Parallel execution of independent actions maximizes throughput
Typical implementations
- ▸NASA Timeliner automated procedure execution on ISS
- ▸JPL IDEA executive for autonomous spacecraft
- ▸ROS actionlib for robotic task execution
Lunar considerations
- ▸Must handle uncertain action outcomes in novel lunar environment
- ▸Execution latency must be low enough for time-critical responses (seconds)
- ▸Must coordinate multiple robotic agents executing concurrent tasks
