1Reliability
If manual configuration of simulation environments is performed, then the training process can be controlled and customized, but the time and labor required for training increase significantly
Solution Approach 1:
The system enables self-service by allowing the robot to automatically generate its own simulation training configurations based on its actual task requirements, eliminating the need for manual human configuration and significantly reducing time and labor投入 while maintaining training effectiveness
Solution Approach 2:
The system performs preliminary action by pre-generating multiple simulation configuration files with different environmental parameters, obstacle distributions, and task scenarios before actual training begins, allowing the robot to undergo extensive training across diverse conditions without requiring manual setup for each scenario
2Adaptability or versatility
If numerous simulations are performed to train the machine learning algorithm, then the robot's adaptability improves, but the computational resources and time required increase
Solution Approach 1:
The system segments the training process by decomposing complex tasks into multiple sub-activities and generating specialized simulation configurations for each sub-task, allowing parallel processing and more efficient utilization of computational resources while maintaining comprehensive adaptability training
Solution Approach 2:
The system employs parameter changes by automatically varying simulation environment parameters such as obstacle positions, task locations, and environmental conditions across multiple configuration files, enabling the robot to learn diverse scenarios through systematic parameter variation rather than manual scenario design
3Manufacturing precision
If manual configuration data is generated to be highly correspondent to the domain, then the trained model is effective, but the complexity of the configuration process increases
Solution Approach 1:
The system eliminates configuration complexity by enabling the robot to self-generate accurate domain-correspondent configuration files automatically based on its task specifications, removing the need for manual expert configuration while maintaining high precision through algorithmic generation
Solution Approach 2:
The system introduces an intermediary automated planning component that translates the robot's task requirements into precise simulation configuration parameters, serving as a mediator between high-level task specifications and low-level simulation settings, thereby ensuring accuracy without requiring manual intervention
