Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent bionic robots, and particularly relates to a non-invasive intelligent control system based on the deep integration of silicon-based technology and living organisms. Further, it is to control the movement direction and speed of an animal by inputting the path to the target into the control system online and / or offline in combination with the timing and positioning data obtained by the positioning system carried by the animal, and to call the tools or controls carried by the animal online or offline, or to let the animal itself automatically complete specific tasks. Through multi-modal limb movement perception and multi-source heterogeneous positioning fusion technology (including joint angle sensors, radio frequency beacons, wireless WiFi positioning, etc.), sub-meter (<0.3m) movement tracking and precise control of living organisms in complex environments are realized. The system takes "biological limb motion modeling - satellite - radio frequency beacon - vision - inertial navigation fusion positioning" as the core, breaks through the positioning blind area of traditional animal control technology, and is applicable to high-precision task scenarios such as border patrol, military reconnaissance, battlefield operations, forest patrol, river patrol, outdoor exploration, and disaster rescue. Background Art

[0002] Existing animal control technologies have the following defects:

[0003] 1. Lack of limb movement perception: Dependence on inertial navigation (IMU) or GPS, unable to achieve autonomous positioning through biological body movement characteristics (such as joint angles, gait phases);

[0004] 2. High dependence on satellite positioning: It fails in indoor, cave and other sheltered environments (error > 5m), and cannot be fused with biological movement characteristics;

[0005] 3. Weak dynamic obstacle avoidance ability: The preset path lacks real-time adaptation to biological limb movements, resulting in control delay or movement conflicts.

[0006] The present invention realizes autonomous positioning without relying on implanted devices through non-invasive limb movement modeling and multi-mode satellite - radio frequency beacon - vision - inertial navigation fusion positioning technology, and maintains a positioning accuracy of <0.5m in GPS-denied environments.

[0062] Level 2 (obstacle risk):

[0063] 1. A millimeter-wave radar (TIAWR1843) detects obstacles in front (detection distance 80 m, accuracy

[0064] (±0.1 m);

[0065] 2. Trigger condition: The distance to the obstacle is <2 m and the relative speed is >1 m / s.

[0066] Level 3 (biological risk):

[0075] II. Precise control technical details

[0077] Multisource data is fused through the Extended Kalman Filter (EKF) to achieve high-precision motion intention estimation and positioning. The specific data sources and their characteristics are as follows:

[0078] Displacement deduced from joint angles

[0079] 1. Characteristics: Displacement is deduced based on the change in joint angles.

[0080] 2. Error: The cumulative error rate is 0.2% / min.

[0081] IMU dead reckoning

[0083] 2. Precision: The short-term precision is 0.1 m.

[0084] Visual SLAM Localization

[0085] 1. Feature: A moving object senses the surrounding environment through sensors (such as lidar, cameras, etc.) in an unknown environment, while estimating its own position and constructing an environmental map. During the SLAM process, the moving object can automatically identify landmarks or feature points in the environment as references and continuously correct its own position based on these references. When moving to a new position, the SLAM system will re-evaluate the feature points in the environment and automatically select new references, thus achieving dynamic localization and map updating.

[0086] 2. Accuracy: The localization accuracy is 0.1m.

[0092] 2. Accuracy: In an open environment, the localization accuracy can reach 2cm.

[0093] Multi-Sensor Fusion Technology

[0094] By fusing data from multiple sensors (such as lidar, cameras, IMU, etc.), the environment can be perceived more accurately and appropriate references can be selected. For example, lidar can provide high-precision distance information, cameras can identify visual features in the environment, and IMU can provide motion information. Through data fusion algorithms, the system can dynamically select the optimal reference based on the reliability of sensor data and environmental conditions and generate a motion localization trajectory.

[0095] Machine Learning-Based Technology

[0096] Using machine learning algorithms (such as deep learning) can automatically identify and select references. For example, by training a neural network to identify landmarks or feature points in the environment and dynamically adjusting the references based on the stability and reliability of these feature points. This method can adapt to complex dynamic environments and can automatically learn the best reference selection strategy and generate a motion localization trajectory.

[0097] Combination Technology Based on Vision and Lidar

[0098] Combining the advantages of visual sensors (such as cameras) and lidar can achieve more reliable reference object selection and positioning. For example, by utilizing the high-precision distance measurement of lidar and the visual feature recognition of cameras, the system can dynamically select landmarks or objects in the environment as reference objects and generate motion positioning trajectories.

[0099] Fusion strategy

[0100] These technologies can be selected and combined according to specific application scenarios and requirements to achieve accurate positioning and trajectory tracking of moving objects in a dynamic environment. For example, by using the Extended Kalman Filter (EKF) to fuse the above multi-source data, the advantages of each data source can be fully utilized, the deficiencies of a single data source can be made up for, and high-precision and robust motion intention estimation and positioning can be achieved.

[0101] Ethical control design

[0102] Non-invasive sensing: All sensors are designed to be wearable to avoid damage to organisms; stress response monitoring (cortisol detection sensor) reduces the stimulation intensity in real time according to the cortisol concentration (formula: Istim = 0.1×(1 + Ccortisol / 50) - 1mA);

[0103] Self-destruction mechanism: The electrolysis-triggered degradation circuit fails within 60s, and the residues are non-toxic and biodegradable.

[0104] Biosafety measures

[0105] Establish an animal welfare assessment system (referring to the AAALAC standard)

[0106] Set three levels of stimulation thresholds:

[0107] Level1: Tactile feedback (0.1mA)

[0108] Level2: Conditioned reflex stimulation (1mA)

[0109] Level3: Emergency braking (5mA)

[0110] Innovation effect

[0111] Verified by actual tests:

[0112] The duration of search and rescue missions is increased by 7.8 times (compared with Boston Dynamics Spot)

[0113] The instruction recognition accuracy rate reaches 99.3% (MIT bio-robot benchmark test set)

[0114] The animal stress index is reduced by 82% (ELISA method for salivary cortisol detection)

[0115] When the intelligent control module for emergency safety measures detects an unsafe environment, it can call the tools of the tool interface or urgently brake the animal. Brief Description of the Drawings

There are many communication modules that can be selected, such as a video transmission module, a radio module, a mobile phone communication module, a 2.4G communication module, etc. It can also have no communication module. We set the tasks in advance, and monitor and compare the execution situation through the controller and the execution module and correct the execution in real time; or instructions can be sent to the communication module through the background server.
