Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a robot arm performs operations on a target object without changing hold positions, then the operation can be executed simply, but the precision of the operation deteriorates
Solution Approach 1:
The system performs preliminary actions by calculating the hand area and determining optimal hold points before the robot arm executes the operation. The region calculation unit computes the hand area based on operation information and object images, and the hold point calculation unit determines precise hold points within this area, enabling high-precision operations while maintaining ease of execution
Solution Approach 2:
The patent replaces mechanical trial-and-error adjustment with computational methods. Instead of physically adjusting hold positions through mechanical means, the system uses image processing and mathematical calculations to determine optimal hold points, achieving both precision and operational simplicity
2Manufacturing precision
If the robot arm calculates and adjusts hold points based on hand area, then the operation precision improves, but the device complexity increases
Solution Approach 1:
The patent introduces an information processing apparatus as an intermediary between the robot arm and the target object. This intermediary contains the region calculation unit and hold point calculation unit that process operation information and object images to determine optimal hold points, thereby achieving precision without directly complicating the robot arm's mechanical structure
Solution Approach 2:
The system creates a digital representation (copy) of the target object through image acquisition and processing. By working with this digital copy to calculate hand area and hold points, the system achieves precision planning without physical complexity, separating the computational complexity from the mechanical execution

AI summary
An information processing apparatus according to an embodiment of the present technology includes a region calculation unit. The region calculation unit calculates, on the basis of operation information regarding an operation performed on a target object and an image of the target object, a hand area when the operation is performed on the target object by using an image generator or a predictor. This enables a high-precision operation. Moreover, a dataset used for the image generator and the predictor can be collected more easily. Therefore, a massive amount of datasets can be built and can be applied to various target objects.
