Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical testing is conducted to evaluate and compare robots, then accurate performance measurement is achieved, but time consumption increases, costs increase, and risk of damage increases
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the robot that replicates its physical properties, sensors, and behaviors. This virtual replica is then tested in simulated environments, eliminating the need for physical testing while maintaining measurement accuracy. The digital twin approach allows repeated testing without wear, damage, or time constraints associated with physical robots.
Solution Approach 2:
The patent introduces a simulation environment as an intermediary between the robot and the testing process. Instead of directly testing physical robots, the system uses a virtual environment that mimics real-world conditions, allowing performance evaluation without the drawbacks of physical testing including time consumption, cost, and risk of damage.
2Loss of information
If physical testing is conducted to evaluate and compare robots, then performance data is obtained, but cost increases due to purchasing multiple robots and risk of damage
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the robot that replicates its physical properties, sensors, and behaviors. This virtual replica is then tested in simulated environments, eliminating the need for physical testing while maintaining measurement accuracy. The digital twin approach allows repeated testing without wear, damage, or time constraints associated with physical robots.
3Ease of operation
If sensors are used in physical robots for navigation, then autonomous navigation is achieved, but malfunction risk increases causing mistakes and collisions
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the robot that replicates its physical properties, sensors, and behaviors. This virtual replica is then tested in simulated environments, eliminating the need for physical testing while maintaining measurement accuracy. The digital twin approach allows repeated testing without wear, damage, or time constraints associated with physical robots.
Solution Approach 2:
The patent uses simulation to pre-test and validate robot navigation algorithms in controlled virtual environments before deploying them to physical robots. This beforehand testing identifies and corrects potential sensor malfunction issues and navigation errors without risking damage to physical robots or their surroundings.

AI summary
A method for evaluating robots in simulation, when executed on a computing device, involves the following steps: obtaining a robot description file created based on the physical properties of a robot, obtaining an environment description file created based on an environment, and obtaining an obstacle description file. A physics simulation engine creates a virtual environment based on the environment description file and obstacle description file. A virtual robot is created based on the robot description file. When the virtual robot navigates from the starting area to the ending area within the virtual environment based on navigation information, the physics simulation engine outputs simulation information. The robot navigation program generates and sends navigation information to the physics simulation engine based on the simulation information. When the virtual robot reaches the ending area, the physics simulation engine outputs evaluation information.
