Engineering Contradiction Analysis
1Reliability
If manual configuration of simulation environments is used, then the training process can be controlled and customized, but the time and effort required for training increases significantly
Solution Approach 1:
The system enables automated self-configuration of simulation environments through the HTN planner, which autonomously generates configuration files based on domain information and user-defined criteria without requiring manual human intervention for each simulation setup
Solution Approach 2:
The HTN planner performs preliminary decomposition of training activities into sub-activities and pre-generates configuration files before actual training begins, allowing simulations to be set up in advance and executed efficiently without manual configuration during the training process
2Adaptability or versatility
If numerous simulations are performed for successful robot training, then the machine learning algorithm can adapt effectively, but the computational resources and time required increase
Solution Approach 1:
The HTN planner decomposes complex training activities into hierarchical sub-activities, organizing simulations into structured sequences that target specific skills and behaviors, making the training process more efficient and manageable while maintaining comprehensive coverage
Solution Approach 2:
The system dynamically adjusts simulation parameters and configuration based on the decomposed sub-activities and user-defined criteria, varying environmental conditions, robot capabilities, and task requirements to create diverse training scenarios that improve robot adaptability without requiring exhaustive simulation sets
3Adaptability or versatility
If manual configuration files are generated for each simulation, then specific training scenarios can be created, but the complexity and effort of configuration increases
Solution Approach 1:
The HTN planner automatically generates configuration files by itself based on domain information and user-defined criteria, eliminating the need for manual configuration and reducing the complexity of setting up diverse simulation scenarios
Solution Approach 2:
The system pre-processes domain information and user criteria to generate configuration files in advance, organizing training scenarios hierarchically through activity decomposition, which simplifies the configuration process and reduces manual effort required for each simulation
