[0002] In many areas of human production and life, robotic arm technology has become a key supporting technology. It is widely used in industrial automation and environmental cleaning, enabling operators to complete complex tasks without having to be in dangerous environments or perform high-risk tasks, thus ensuring operational efficiency and personnel safety.
[0003] In existing technologies, teleoperation is the primary method for controlling robotic arms. Operators use specific control devices or interactive interfaces to send commands to the robotic arm and receive feedback environmental perception data and execution information, thereby constructing a closed-loop control system of "perception-decision-execution".
[0004] In the process of realizing this invention, the inventors discovered the following defects in the prior art: (1) Operators usually need to use complex interactive interfaces and cumbersome operation methods to control the robotic arm, which makes the operation interaction process complicated and seriously reduces the efficiency of the robotic arm; (2) In cluttered scenes, the target object is easily obscured or interfered with, making it difficult for the operator to accurately recognize and precisely locate it, which in turn causes a deviation between the operation intention and the actual action of the robotic arm, resulting in misoperation; (3) The prior art lacks understanding of some of the operator's operation postures, making it difficult to accurately capture subtle movement intentions, which further affects the accuracy and reliability of the robotic arm in performing complex operations.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0032] It should be noted that the terms "first," "second," and "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0033] Example 1
[0034] Figure 1 This is a flowchart of a robotic arm teleoperation method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the motion path and end-effector pose of the robotic arm are determined based on real-time visual information of the operation scenario. The method can be executed by a robotic arm teleoperation device, which can be implemented by software and / or hardware and is generally integrated into an electronic device, which can be a robotic arm control device.
[0035] Correspondingly, such as Figure 1 As shown, the method includes the following operations:
[0036] S110: Collect real-time visual information of the target operation scene.
[0037] The real-time visual information of the target operation scene can be visual data about the operation environment acquired in real time by an image acquisition device when the robotic arm performs the operation task. For example, the real-time visual information of the target operation scene may include, but is not limited to, the spatial geometric information of the target interactive object and the interactive posture information of the target user. This embodiment of the invention does not limit the specific content of the real-time visual information of the target operation scene.
[0038] In this embodiment of the invention, the robotic arm performing the operation task can be designated as the target robotic arm, and the operation scene in which the target robotic arm performs the operation task can be designated as the target operation scene. Before controlling the target robotic arm to perform the operation task, the robotic arm control device can first collect real-time visual information of the target operation scene based on a camera or a visual sensor such as an RGB-D (Red-Green-Blue-Depth) camera, so as to perform motion planning for the target robotic arm based on the real-time visual information of the target operation scene.
[0039] S120. Based on the real-time visual information of the target operation scenario, perform motion planning on the target robotic arm to determine the target path and target end-effector pose of the target robotic arm.
[0040] The target path can be the motion path of the target robotic arm when performing the operation task. The target end effector pose can be the position and orientation of the end effector in three-dimensional space when the target robotic arm performs the operation task.
[0041] Correspondingly, after collecting real-time visual information of the target operation scene, the robotic arm control device can analyze the real-time visual information of the target operation scene to determine the target path and target end pose of the target robotic arm when performing the operation task, thereby ensuring that the target robotic arm completes the operation task along the optimal path at the correct angle and position.
[0042] S130. Control the target robotic arm to interact with the target interactive object according to the target path and target end pose of the target robotic arm.
[0043] The target interaction object can be any object that the target robotic arm needs to physically contact, manipulate, or interact with during the execution of its tasks. For example, in the field of industrial automation, the target interaction object may include, but is not limited to, workpieces, tools, and materials; in the field of medical robotics, the target interaction object may include, but is not limited to, medical equipment and tools; in the field of construction, the target interaction object may include, but is not limited to, building materials such as bricks and beams. This embodiment of the invention does not limit the specific field in which the target robotic arm performs its tasks or the specific type of the target interaction object.
[0044] Accordingly, after performing motion planning on the target robotic arm based on the real-time visual information of the target operation scenario, and determining the target path and end-effector pose of the target robotic arm, the robotic arm control device can convert the target path and end-effector pose of the target robotic arm into corresponding control commands, and send the control commands to the target robotic arm to control the target robotic arm to interact with the target interactive object.
[0045] This invention collects real-time visual information of the target operation scene and performs motion planning for the target robotic arm based on this information. This determines the target path and end-effector pose of the robotic arm, allowing for interaction between the robotic arm and the target interactive object. By planning the motion path and end-effector pose using real-time visual information of the target operation scene, this solution provides precise navigation for the robotic arm's operation, reducing operational errors caused by path deviations or improper postures. It solves the problems of low operational accuracy in existing technologies due to complex and chaotic operation processes, insufficient understanding of user intent, and simplifies the robotic arm's operation process, enhancing its accuracy and reliability, and ultimately improving its utilization efficiency.
[0046] Example 2
[0047] Figure 2 This is a flowchart of a robotic arm teleoperation method provided in Embodiment 2 of the present invention. This embodiment is a specific implementation based on the above embodiment. In this embodiment, various specific optional implementation methods are given for motion planning of the target robotic arm based on real-time visual information of the target operation scene, determining the target path and target end-effector pose of the target robotic arm. Correspondingly, as... Figure 2 As shown, the method in this embodiment may include:
[0048] S210. Collect real-time visual information of the target operation scene.
[0049] S220. Generate a virtual model of the target interactive object based on the spatial geometric information of the target interactive object.
[0050] The spatial geometric information of the target interactive object can be data describing the geometric features of the target object in three-dimensional space, such as its shape, size, position, and depth. The virtual model of the target interactive object can be a digital representation used to describe the geometric features and physical properties of the target interactive object.
[0051] Specifically, after acquiring real-time visual information of the target operation scene, the robotic arm control device can accurately construct a virtual model of the target interactive object based on the spatial geometric information of the target interactive object using computer modeling technology. This virtual model can not only accurately reflect the appearance characteristics of the target interactive object, but also include its physical attributes and dynamic behavior information, thus providing a comprehensive and accurate reference for the subsequent operation of the robotic arm.
[0052] In an optional embodiment of the present invention, generating a virtual model of the target interactive object based on the spatial geometric information of the target interactive object may include: classifying the target interactive object based on the spatial geometric information of the target interactive object to obtain a classification result of the target interactive object; and generating a virtual model of the target interactive object based on the classification result of the target interactive object and the spatial geometric information.
[0053] The classification result of the target interactive object can be the final output of classifying the target interactive object into a specific category through a certain classification method or algorithm.
[0054] In this embodiment of the invention, during the process of generating a virtual model of the target interactive object based on its spatial geometric information, the spatial geometric information of the target interactive object can first be input into a machine learning model to classify the target interactive object, thereby obtaining a classification result. Further, the spatial geometric information, including the depth information of the target interactive object, can be converted into three-dimensional coordinates of the target interactive object in virtual space. Combined with the classification result of the target interactive object, a virtual model belonging to the same category and having the same physical properties as the target interactive object is generated in virtual space. This allows the target robotic arm to plan and adjust its operation strategy in advance based on the characteristics of the virtual model. Simultaneously, this virtual model can also provide a more accurate reference for the motion planning and collision detection of the target robotic arm.
[0055] Figure 3 This is a schematic diagram of the structure of a robotic arm teleoperation system provided in Embodiment 2 of the present invention. Figure 4 This is a specific flowchart of a robotic arm teleoperation process provided in Embodiment 2 of the present invention. In a specific example, the robotic arm teleoperation system can include two parts: a physical space and a digital space. The visual detection module in the physical space can use an RGB-D camera to acquire real-time visual information of the target operation scene. Furthermore, the 3D reconstruction module in the digital space can include an object recognition module and a model generation module. Specifically, the object recognition module can perform object recognition on the target interactive object based on the real-time visual information of the target operation scene to determine the classification of the target interactive object. Further, the model generation module can convert the depth information in the real-time visual information of the target operation scene into the 3D coordinates of the target interactive object in virtual space, and use the object recognition result to generate a virtual object in virtual space with the same category and physical properties as the target interactive object, thereby restoring the real 3D interactive scene.
[0056] S230. Generate the operation task of the target robotic arm based on the interaction posture information of the target user and the virtual model of the target interaction object.
[0057] The target user can be the user who remotely operates the target robotic arm. The target user's interaction posture information can include their body posture, gestures, body language, and other interaction-related bodily state information during human-computer interaction. For example, the target user's interaction posture information may include, but is not limited to, the posture of their arm and the degree of finger bending. The target robotic arm's operation task can be the specific work or action that the target robotic arm needs to perform in the target operation scenario.
[0058] Specifically, after generating a virtual model of the target interactive object based on its spatial geometric information, the robotic arm control device can comprehensively analyze the interactive posture information of the target user and the virtual model of the target interactive object to generate the target robotic arm's operation task.
[0059] In an optional embodiment of the present invention, the step of generating the operation task of the target robotic arm based on the interaction posture information of the target user and the virtual model of the target interaction object may include: performing intent recognition on the interaction posture information of the target user to determine the interaction operation intent of the target user; and generating the operation task of the target robotic arm based on the interaction operation intent of the target user and the virtual model of the target interaction object.
[0060] Among them, the interactive operation intent can be the target user's target or desired behavior conveyed to the target robotic arm through interactive posture information.
[0061] Specifically, when generating the target robotic arm's operational tasks based on the target user's interactive posture information and the virtual model of the target interaction object, the robotic arm control device first uses artificial intelligence to monitor and analyze the target user's interactive posture information in real time, understanding the target user's intentions and needs, thereby determining the target user's interactive operation intentions. Furthermore, the robotic arm control device can generate the target robotic arm's operational tasks based on the target user's interactive operation intentions and the virtual model of the target interaction object.
[0062] like Figure 3As shown, in a specific example, the digital space of the robotic arm teleoperation system can also include an intent understanding module. This intent understanding module includes a hand recognition module, a gesture understanding module, and a layout understanding module. Specifically, the hand recognition module can use a machine learning model to extract features such as the shape, contour, and key points of the hand from the target user's interactive posture information. Further, the gesture understanding module can classify the hand based on the features extracted by the hand recognition module to determine whether the target user is facing the RGB-D camera with their palm or the back of their hand. Further, combining the hand orientation, the extracted key points of the finger joints, finger direction, and curvature can be mapped to corresponding actions based on preset rules. For example, a palm facing outwards and fingers pointing downwards represents a pushing action; fingers pointing downwards and bent together represent a grasping action; fingers rotating left and right while maintaining the same curvature represents a twisting action. After obtaining the target user's corresponding actions based on the gesture understanding module, the layout understanding module can use the machine learning module to classify the real-time visual information of the RGB-D camera image input, i.e., the target operation scene, to determine the target user's interactive operation intent. The gesture-based control method described above makes operation more intuitive and natural, eliminating the need for complex control interfaces and cumbersome operation steps. Compared to traditional robotic arm teleoperation methods, it simplifies the operation process, reduces the learning curve, and improves the accuracy and efficiency of robotic arm operation.
[0063] Optionally, the layout understanding module can also embed prior knowledge of interactions into the classification model by introducing CAM (Class Activation Map) activation constraints. Specifically, firstly, a CNN (Convolutional Neural Network) classification model can be trained using training samples to enable the model to classify image inputs from an RGB-D camera. Further, the trained classification model can be used to perform global average pooling on the feature maps of the last convolutional layer to obtain channel weights, which can then be used to obtain CAM maps for specific categories through weighting operations. During training, for images from an RGB-D camera, i.e., real-time visual information of the target operation scene:
[0064] F k =∑ x,y f k (x, y)
[0065] Among them, F k f is the global average pooling result of the k-th channel on the last convolutional layer. k (x, y) is the activation value of the feature map at position (x, y) on the k-th channel of the last convolutional layer.
[0066] Therefore, for image category c, the input to the softmax activation layer is:
[0067]
[0068] Among them, S c For image category c, the input to the softmax activation layer, For F k For the weights of image category c. If F k As scores for different image categories, then:
[0069]
[0070] Furthermore, M c (x, y) is a CAM defined as class c:
[0071]
[0072] Sc=∑ x,y M c (x,y)
[0073] Among them, M c (x, y) represents the importance of the activation value at (x, y) to the image category c, M c The larger (x, y) is, the more important the feature at that position is to category c.
[0074] Optionally, activation constraints can be set based on prior knowledge of the interactions. These constraints can be defined based on features such as the distribution, size, and shape of the CAM. For example, the classification model can be set to give higher attention to specific regions of a certain category. In grasping operations, this typically means the target robotic arm should grasp object A placed on object B, rather than object B itself, or it should place the object in a region of the same category as the object. Furthermore, activation constraints can be incorporated into the training of the classification model. By adding corresponding penalty terms to the loss function, the classification model can be optimized, allowing it to consider the influence of prior knowledge during training and try to satisfy the activation constraints. This controls the target robotic arm to perform specific actions and prevents collisions or erroneous operations.
[0075] S240. Based on the operation task of the target robotic arm, perform motion planning on the target robotic arm to determine the target path and target end-effector pose of the target robotic arm.
[0076] Specifically, after generating the target robotic arm's operation task based on the target user's interaction posture information and the virtual model of the target interactive object, the robotic arm control device can analyze the operation task to determine its specific content. Furthermore, based on the specific content of the operation task, the robotic arm control device can perform motion planning to determine the optimal path for the target robotic arm from its current position to the target position, and use this path as the target path. Simultaneously, based on the shape, size, and required operation type of the target interactive object, the robotic arm control device can accurately calculate the target end effector pose of the target robotic arm to ensure that the end effector can interact with the target interactive object in the correct posture and position.
[0077] In an optional embodiment of the present invention, the step of performing motion planning on the target robotic arm according to the operation task of the target robotic arm to determine the target path and target end-effector pose of the target robotic arm may include: determining the target path and a first end-effector pose of the target robotic arm according to the operation task of the target robotic arm; matching the operation task of the target robotic arm with the end-effector pose database of the target robotic arm to obtain a second end-effector pose of the target robotic arm; and determining the target end-effector pose of the target robotic arm according to the first end-effector pose and the second end-effector pose.
[0078] The first end-effector pose can be the pose of the end effector of the target robotic arm determined during the path planning process. The end-effector pose database can be a collection of data storing the poses required by the end effector of the robotic arm in different operational tasks. The second end-effector pose can be the pose of the end effector of the target robotic arm that matches the operational task of the target robotic arm in the end-effector pose database.
[0079] Specifically, when performing motion planning for the target robotic arm based on its operational tasks, and determining the target path and target end-effector pose, the target path and first end-effector pose of the target robotic arm can first be determined based on its operational tasks.
[0080] In a specific example, such as Figure 3 and Figure 4 As shown, the digital space of the robotic arm teleoperation system can also include a motion planning module. This motion planning module can include a trajectory planning module and an end-effector pose fusion module. Specifically, the trajectory planning module can first determine the current and target positions of the robotic arm based on real-time visual information of the target operation scene or by the target user. Furthermore, it can use heuristic methods based on Riemannian motion strategies to search for the optimal path from the current position to the target position, thereby improving the robotic arm's motion accuracy and efficiency, and enhancing its ability to adapt to complex motion planning problems.
[0081] For example, if the path of the target robotic arm from its current position to its target position is represented as q(t), then the Riemann metric of the path can be expressed as:
[0082]
[0083] Where g(i,j) is the Riemann metric matrix of the path. Let be the local metric function for the path, and q be the position vector of the end effector joint of the target robotic arm, i.e., the path of the target robotic arm from its current position to its target position. Let be the derivative of the joint velocity of the end effector of the target robotic arm, i.e., the joint acceleration.
[0084] Furthermore, the end-effector pose matching module can match the target robotic arm's operation task with the target robotic arm's end-effector pose database, thereby filtering out a second end-effector pose that matches the target robotic arm's operation task from the end-effector pose database. For example, if the target robotic arm's operation task is to unscrew a horizontal bottle cap, then the second end-effector pose could be horizontally holding a cylindrical object.
[0085] Optionally, an end-effector pose database can be pre-established based on the target interaction object obtained by the intent understanding module and the recognized gestures. Understandably, if the gestures recognized by the intent understanding module do not match the target user's interaction posture information, the data can be manually removed.
[0086] The size of the end-effector pose database can be:
[0087] S = N ob *N op
[0088] Where S is the capacity of the end-effector pose data, and N ob N represents the number of target interaction objects. op The number of target end poses.
[0089] After obtaining the first and second end-effector poses, the end-effector pose fusion module can use these poses as input to a DQN (Deep Q Network) to obtain the fused target end-effector pose. This approach can effectively improve the success rate of the robotic arm in grasping objects while correctly understanding the target user's operational intent, and reduce the possibility of misoperation.
[0090] In an optional embodiment of the present invention, after performing motion planning on the target robotic arm according to the operation task of the target robotic arm and determining the target path and target end-effector pose of the target robotic arm, the method may further include: performing interactive operation simulation based on real-time visual information of the target operation scene, the target path of the target robotic arm, and the target end-effector pose to obtain interactive operation simulation results; if it is determined that there is a collision conflict in the interactive operation simulation results, the operation of performing motion planning on the target robotic arm according to the operation task of the target robotic arm and determining the target path and target end-effector pose of the target robotic arm is re-executed until it is determined that there is no collision conflict in the operation simulation results.
[0091] The interactive operation simulation results can be the output results obtained by simulating the execution process of the target robotic arm's operation task. Collision conflicts can be the situations where the target robotic arm collides with other objects while performing the operation task along the target path in the target end-effector pose.
[0092] During the execution of the target robotic arm's task, objects in the target operation scene may shift or new objects may be added. Therefore, after determining the target path and end-effector pose of the target robotic arm, interactive operation simulations can be performed based on real-time visual information of the target operation scene, the target path of the target robotic arm, and the end-effector pose to ensure that the target robotic arm does not collide with obstacles in the target operation environment while performing the task along the target path. If collision conflicts exist in the interactive operation simulation results, the motion planning of the target robotic arm can be re-executed according to the target robotic arm's task until no collision conflicts are found in the operation simulation results.
[0093] Optionally, after determining the target path for the robotic arm, optimization algorithms such as gradient descent can be used to optimize the searched path to improve its quality. Furthermore, paths can be evaluated and compared using metrics such as path length, time efficiency, and stability to select the optimal path as the target path for the robotic arm.
[0094] S250. Control the target robotic arm to interact with the target interactive object according to the target path and target end pose of the target robotic arm.
[0095] In a specific example, such as Figure 3 and Figure 4As shown, the digital space of the robotic arm teleoperation system can also include a virtual communication module, and the physical space can also include a robot operation module. Specifically, the virtual communication module can include, but is not limited to, wireless communication interfaces and wired communication interfaces, mainly including WIFI (Wireless Fidelity), Bluetooth, TCP / IP (Transmission Control Protocol / Internet Protocol), and UDP / IP (User Datagram Protocol / Internet Protocol), etc., which can ensure reliable real-time data communication between the digital space and the physical operation space, and convert the processed gestures and intentions into control commands and send them to the robot operation module to make the target robotic arm perform corresponding actions.
[0096] This invention collects real-time visual information of a target operation scene, including the spatial geometry of the target interactive object and the interactive posture information of the target user, and generates a virtual model of the target interactive object based on its spatial geometry. Further, it generates an operation task for the target robotic arm based on the interactive posture information of the target user and the virtual model of the target interactive object. Then, it performs motion planning on the target robotic arm based on the operation task, determining the target path and end-effector pose, and controlling the interaction between the target robotic arm and the target interactive object based on the target path and end-effector pose. This solution plans the motion path and end-effector pose of the target robotic arm using real-time visual information of the target operation scene, providing precise navigation for the robotic arm's operation. This reduces operational errors caused by path deviations or improper postures, solving the problems of low operational accuracy in existing technologies due to complex and chaotic operation processes, insufficient understanding of user intent, and other issues. It simplifies the robotic arm's operation process, enhances the accuracy and reliability of robotic arm operation, and ultimately improves the efficiency of robotic arm use.
