ANKLE JOINT MOTION RECOGNITION SYSTEM AND ALGORITHM OPTIMIZATION BASED ON PLANTAR PRESSURE SCIE
期刊论文 | 2024 | JOURNAL OF MECHANICS IN MEDICINE AND BIOLOGY
Abstract&Keyword Cite

Abstract :

Due to the current focus of research on ankle rehabilitation robots on structural design, there is still limited research on ankle human-machine interaction technology. In order to enable rehabilitation robots to conduct personalized rehabilitation training based on patients' ankle movement intentions, we propose a new ankle motion recognition method based on plantar pressure. First, we designed a plantar pressure collection system based on array sensors. Then, we collected nine types of ankle joint motion pressure data from five volunteers and conducted algorithm selection, data processing, and algorithm optimization. Finally, we proposed a small sample optimization algorithm based on support vector machine, with an average recognition rate of 93.16%. The recognition method proposed in this paper can be combined with ankle rehabilitation robots to achieve active rehabilitation functions, laying the foundation for the clinical application of active rehabilitation technology.

Abstract :

为了研究一个典型的风力机塔筒在风-地震耦合作用下的结构性能。通过有限元软件ABAQUS建立塔筒的精细模型,并对其进行非线性时程分析。其中,风载荷基于IECKaimal谱,根据叶素动量理论(BEM),由风力机载荷计算软件Ashes输出叶片载荷;且将运行状态分为正常运行与故障运行。同时,为了研究不同周期地震波作用下塔筒的结构响应以及失效形式,将地震运动分为两组,一组为短周期地震,另一组为长周期地震。研究发现在风-地震耦合作用下塑性铰首先出现在风力机塔分段连接处,这与风单独作用时失效位置相同;且在短周期地震作用下一旦形成塑性铰将很快导致塔筒整体倒塌;当地震波峰值加速度(PGA)相近时,长周期地震对运行中风力机塔的结构性能影响较大。

Abstract :

In this paper, we propose a pneumatic double-joint soft actuator based on fiber winding and build a dexterous hand with 11 degrees of freedom. Firstly, soft actuator structural design is carried out according to the actuator driving principle and gives the specific manufacturing process. Then, an experimental analysis of the bending performance of a single soft actuator, including bending angle, speed, and force magnitude, is carried out by building a pneumatic control experimental platform. Finally, a series of dexterous robotic hand-grasping experiments is conducted. Different grasping methods are used to catch the objects and measure the objects' change in height, length, and rotation angle during the experiment. The results show that the proposed soft actuator is more consistent with the bending rule of human fingers, and that the gestures of the dexterous hand are more imaginable and flexible when grasping objects. The soft actuator can carry out horizontal and vertical movements, and rotation of the object in the dexterous hand, thus achieving better human-computer interaction.

Abstract :

Cabinet wiring is a crucial process in the field of electrical engineering. Traditional wiring methods are labor-intensive, time-consuming, and prone to safety hazards. Consequently, robot wiring technology has emerged as a promising solution. This paper investigates how to simulate the cabinet wiring robot using Robot Studio software. The rise of robot wiring technology has brought about novel automation solutions to the field of electrical engineering, improving work efficiency and reducing safety risks. In this automated wiring process, we achieve cabinet automation through the control of upper and lower computers and validate the wiring effectiveness and feasibility of the robot through simulation. During the simulation process, we analyze the relevant parameters of setting reasonable robot offline programming to achieve optimal automation wiring results.

Abstract&Keyword Cite

Abstract :

As one of the important health indicators of the body, plantar pressure distribution has great reference value in clinical medicine, sports and fitness training, and rehabilitation fields. The purpose of plantar pressure collection is to identify the movement patterns and pressure distribution information of the human lower limbs. This article focuses on introducing the design of plantar pressure detection and motion detection systems from the aspects of array plantar pressure sensors, STM32 acquisition circuits, acquisition programs, and gait segmentation recognition algorithms. During the process of human body state recognition, the collection system sequentially scans 16 plantar pressure sensors and transmits the collected data to the pressure measurement recognition software for real-time graphic display and motion recognition. Wireless communication is carried out using WiFi transmission, and repetitive action segmentation and different pose recognition are achieved using gait segmentation algorithm and SVM algorithm. And a detection system experimental platform was built to recognize 8 daily movements such as sitting, standing, and going up and down stairs, with a recognition rate of 93.65%, laying the experimental foundation for motion parameter analysis and foot rehabilitation evaluation. © 2023 IEEE.

Abstract :

Researchers are investigating how to make machines read our body language to make human-machine interaction (HMI) more intelligent and efficient. The lower limbs contain a variety of gestures, and it is also one of the most effective ways to express body information. Therefore, foot gesture recognition (FGR) has become a popular technology for human-machine interface with simple, fast, and accurate features. To give the reader a quick overview of the current state of FGR research, this review takes the sensing methods used in the FGR technology as an entry point, introduces different sensing methods, machine learning algorithms, and applications, and discusses the limitations and future work on FGR systems. The results show that the mainstream sensing methods for FGR are plantar pressure, inertial, visual, surface electromyography (sEMG), and ultrasound (US). Current applications of FGR are simplified control, medical rehabilitation, virtual reality (VR), and smart prosthetics. Research on hybrid sensing methods and deep learning algorithms has gradually increased in recent years. Future research will focus on designing sensor hardware that can respond to environmental changes, using multimodal sensing for interaction, and designing more comfortable and portable FGR systems.
