[0025] It should be noted that the key features of the plate are extracted in the grasping point planning mainly through the edge detection algorithm to calculate the grasping point, the grasping force is mainly calculated by the neural network algorithm, and the path optimization is mainly calculated by the genetic algorithm to calculate the robot's motion path.

[0026] The data acquisition method includes: N1: image acquisition, based on the sensor data, the sensor image of the plate shape and the position and shape information of the obstacle are acquired to obtain the initial plate shape data and the initial obstacle data; N2: data analysis, based on the initial plate shape data and the initial obstacle data, the target image is analyzed to identify the specific shape and size of the plate and the precise position and shape of the obstacle to obtain the analysis result; N3: data fusion, the initial plate shape data, the initial obstacle data and the analysis result are fused to obtain a comprehensive data set containing complete plate shape and obstacle information; N4: data matching, based on the comprehensive data set, the plate shape data and the initial obstacle data are matched to obtain the plate shape data and the obstacle data.

The specific shape and size of the plate and the precise position and shape of the obstacle are identified through the image recognition algorithm.

[0028] The matching method includes the following steps: B1, feature matching, matching based on the plate shape data with the template library, calculating the similarity between the plate feature and the grasping scheme in the template library, selecting the template with the highest similarity as the matching result, and obtaining the matching result; B2, dynamic grasping scheme generation, based on the matching result, extracting the corresponding grasping scheme from the template library, combining the specific shape data and environmental information of the current plate, dynamically adjusting the grasping scheme to obtain the initial dynamic grasping scheme; B3, optimization and verification, based on the initial dynamic grasping scheme, optimizing and verifying the generated dynamic grasping scheme to obtain the dynamic grasping scheme; B4, real-time update, based on the dynamic grasping scheme, monitoring the execution of the grasping action, and feeding back the monitoring data to the system. If the monitoring data does not meet the expectations, it will issue abnormal situations of grasping point offset and insufficient force, dynamically adjust the grasping scheme, and re-match and optimize.

[0029] It should be noted that the plate shape data is first matched with the template library, and the similarity between the plate features and the grasping solutions in the template library is calculated, and the template with the highest similarity is selected as the matching result, thereby obtaining a preliminary matching solution. After obtaining the matching result, the corresponding grasping solution is extracted from the template library, and the generated initial dynamic grasping solution is optimized and verified. Finally, the execution of the grasping action is continuously monitored, and the monitoring data is fed back to the system in real time.

[0030] The method for acquiring real-time monitoring data includes the following steps: A1, dynamic signal acquisition, through distributed sensors, real-time acquisition of various parameters in the process of grasping action performed by the robot, including grasping point, grasping force and grasping posture, to obtain original monitoring data; A2, noise filtering, based on the original monitoring data, denoising the original signal, extracting the effective frequency band signal related to the grasping point, grasping force and grasping posture, to obtain initial monitoring data; A3, feature extraction, based on the initial monitoring data, extracting key features from the initial monitoring data, including the position information of the grasping point, the change trend of the grasping force and the angle change of the grasping posture, to form a feature data set; A4, anomaly detection, based on the feature data set, analyzing the feature data set, identifying abnormal situations in which the grasping force in the grasping action is too large or too small, and the grasping posture deviates from the expected, to obtain an abnormal data set; A4, real-time feedback, based on the abnormal data set, adjusting the robot's grasping action parameters, grasping force and correcting the grasping posture, and finally obtaining real-time monitoring data.

[0031] It should be noted that various parameters of the robot when performing grasping actions are collected in real time through distributed sensors, and feature extraction is performed while the original monitoring data is subjected to noise filtering. The feature data set is then deeply analyzed to identify abnormal situations in the grasping action. These abnormal situations may include grasping force that is too large or too small, grasping posture that deviates from expectations, etc. The system adjusts the robot's grasping action parameters, grasping force, and corrects the grasping posture through the abnormal data set.

[0032] Embodiment 1: In a sheet processing workshop, an intelligent sheet grabbing robot needs to grab sheets from stacked sheets and move them to processing equipment for cutting or drilling. The sheet is a rectangular sheet with a length of 100 cm and a width of 60 cm. The outer surface of the sheet is provided with multiple groups of through holes and is uneven, and the four corners are right angles. The robot is equipped with a high-precision sensor at the execution end to collect shape data of the stacked sheets such as edge contour, hole position, surface convexity, etc. in real time, and match the collected sheet shape data with common sheet shape features in the template library. When the match is successful, a dynamic grabbing scheme suitable for the current sheet is generated. Finally, the grabbing action of the robot is monitored in real time and compared with the preset dynamic grabbing data. If there is a deviation between the monitoring data and the preset data, such as the grabbing point deviates from the target position or the grabbing force is insufficient, the grabbing point is recalculated, the grabbing force is adjusted, and the posture of the robotic arm is optimized. After the robot successfully grabs the sheet, it moves it to the processing equipment according to the optimized path.

[0033] Embodiment 2: In a sheet processing workshop, the intelligent sheet grabbing robot needs to grab sheets from the stacked sheets and transport them to the processing equipment for cutting or drilling. The sheet surface is arc-shaped, and the length is 1120cm, the width is 40cm, and the thickness is 20cm. The outer surface of the sheet is smooth, and the four corners are 60-degree corners. The robot is equipped with a high-precision sensor at the execution end to collect the shape data of the stacked sheets in real time, such as edge contour, hole position, surface convexity, etc., and compares the collected sheet shape data with the common ones in the template library. The shape features of the plate are matched. When the match is unsuccessful, the grasping point, grasping force and grasping posture are recalculated according to the plate shape data to form a new grasping plan, and the new plan is imported into the template library. Finally, the robot's grasping action is monitored in real time and compared with the preset dynamic grasping data. If there is a deviation between the monitoring data and the preset data, such as the grasping point deviates from the target position or the grasping force is insufficient, the grasping point is recalculated, the grasping force is adjusted, and the posture of the robotic arm is optimized. After the robot successfully grasps the plate, it is moved to the processing equipment according to the optimized path.
