IEEE International Conference on robotics and Biomimetics

作者： Rupeng Yuan Fuhai Zhang Ying Zhu Yili Fu The State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin China

Pose tracking is very crucial for robot's autonomous navigation. LIDAR based pose tracking algorithms are widely used due to its high cost-effective advantage. However these methods are likely to give back wrong result if the environment is blocked by the obstacles. In this paper, a visual odometer assisted pose tracking method is proposed to increase the robustness of pose tracking. Statistical index is introduced to evaluate the samples' score of LIDAR based pose tracking. If the result is not credible, the result of visual odometer will compensate the error along the maximum error direction. The experiment shows that the proposed method is able to track the robot correctly if the environment is blocked by obstacles.

作者： Zixin Wang Dapeng Yang Jiaming Li Hong Liu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin China

It is a question of great import for the dexterous prosthesis to realize its continuous, simultaneous and proportional control of multi-DOFs so that its rehabilitation function can be well achieved and its user acceptance rate can be improved. In this paper, we propose a new method, CNMF-HP, which integrates the constrained non-negative matrix factorization (NMF) and the Hadamard product, for estimating 2-DOF wrist movements (DOF-1, flexion/extension; DOF-2, adduction/abduction) from myoelectric signals. Based on this method, the simultaneous control of a multi-fingered prosthesis is verified in this paper. Through establishing the mapping relationship between the wrist movements and the finger movements of the dexterous prosthesis, two grasp control strategies (synchronous and asynchronous) are proposed and successfully applied in operating the dexterous prosthesis to grasp four kinds of objects of different grasping patterns (cylindrical, spherical, tripod and lateral). Then, the performance of different strategies (synchronous/asynchronous control) in the grasping process is compared in terms of the completion time and completion rate of the tasks, in this way the superiority of EMG control proposed in this paper is further verified.

This paper presents the force control strategies and a kind of compliance control strategies of the hydraulic- driven unit (HDU) in the legged robots. The model of HDU is established and the transfer function of the HDU force control system is given. The analysis of the force control strategies is introduced according to the characteristic of the HDU system. Based on the force control strategy called velocity feedback control strategy which performs the best, the virtual model control strategy which is a kind of compliance control strategy is presented to enhance the adaptability of the legged robot. Finally, the experiments are taken on the HDU experiment platform to test the performance of the force control strategies and the compliance control strategy. The landing buffer experiments are taken on the single leg robot to verify the effectiveness of the compliance control strategy. In the landing buffer experiments, the impact force of the single leg robot's knee HDU is about 0.33 time of what it is without the compliance control strategy while landing.

This paper studies the video of text with large field of view, solves the problem of text acquisition when a single frame cannot obtain complete text information. This paper proposes a method for acquiring video text panoramas, which automatically processes video text content by natural scene text positioning, text tracking, image stitching and other methods. First, the text is detected using the YOLO target detection framework. Second, use ECO tracking method to keep track of text. Finally, the local matching and global stitching method are used to obtain a text panorama. Experiments show that the proposed method can automatically process video and obtain high-resolution panoramic images with text parts, which greatly improves the text processing speed and effect of video content.

A Novel Method of Combining Computer Vision, Eye-Tracking, EMG, and IMU to Control Dexterous Prosthetic Hand

IEEE International Conference on robotics and Biomimetics

作者： Chunyuan Shi Le Qi Dapeng Yang Jingdong Zhao Hong Liu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin China

Due to poor robustness, instability, and the heavy burden of use, the traditional myoelectric control method is still powerless in the face of the control of the dexterous prosthetic hand. To solve this problem, a new method (CVEEI), that combines computer vision, eye tracking, electromyogram (EMG) and IMU was proposed in this paper. Firstly, through gazing (eye-tracking) in front of the screen, the grasping pattern of the objects can be fed back to the prosthetic hand controller; Then, the prosthetic hand can be controlled to transport the object to the position expected, on collaboration of both EMG and IMU. In this process, the grasping pattern of all objects can be recognized by computer vision in real-time. Importantly, through comparing the traditional EMG control method (co-contraction to switch) in the transport experiment of the objects, the superiority of this new method in operating the dexterous prosthetic hand was further verified (fast > 1s/single object) in this paper.

作者： Zhiwei Wu Yongjun Sun Fenglei Ni Yiwei Liu Hong Liu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin China

In this paper, a novel spatial geometry of six-dimensional acceleration sensor(SDAS) is designed. And the sensor equation is calculated. The reliability of SDAS is improved by adding redundant line accelerometer. The GDOP(Geometric Dilution of Precision) index used in satellite navigation is introduced into SDAS for configuration evaluation. Compared with the classic cube configuration, the three indexes have improved significantly. The relationship between the output error of the SDAS and the installation error of the linear accelerometer is analyzed theoretically. Compared with the proposed layout structure using 12 accelerometers, it has obvious advantages.

The state-of-art dexterous prosthetic hand with multi-degree-of-freedom urgently requires a control method to match its dexterity. The purpose of this paper is to develop a method on rapid grasp control of prosthetic hand based on eye-tracking and verify its effectiveness by experiments. Firstly, an interactive experiment platform was established. Based on the platform, the operator can select the necessary grasping pattern from a graphic interface through eye movement and trigger the selected pattern by gazing the target for a short time (~300ms). The selected grasp pattern will be fed back to the operator during the hand prosthesis performing reach-and-grasp tasks. Finally, to verify the effectiveness of this method, experiments were conducted by an able-bodied participant wearing the prosthesis to grasp some daily-used objects. Our result shows that, by adopting the eye tracking technology in the human visual channel, the grasp control of the prosthesis can be supervised and regulated in real-time and thus an effective interaction between the dexterous prosthesis and the operator can be achieved.

International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI)

作者： Longzhi Zhang Dongmei Wu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin China

Visual tracking is a popular topic in computer vision, which has broad application prospects in military guidance, aerospace, video surveillance and analysis, medical diagnosis, intelligent robotics, human-computer interaction, and etc. Current tracking algorithms perform poorly in specific scenes, such as a target in condition of weak light. Thus, a pose tracking method based on visual information is put forward, to implement real-time visual tracking in weak light. More precisely, in proposed method, target pose parameters are known at the first frame in a given video sequence, additionally, edge features and point features are taken as visual features to improve the realtime of tracking. The experimental results demonstrate that our approach has better real-time performance of tracking in weak light.

In this paper, the servo system mechanical drive is analyzed, flexible beam vibration will cause end point trajectory distortion. Simplify the flexible beam load as a second-order system, which is a low frequency light damped vibration system, the ZVD input shaper which is very suitable for vibration suppression of low frequency light damping system is adopted. Due to the different vibration frequencies and damping coefficients of the X-Y platform flexible load, the X-axis and Y-axis input shapers cause different command lags, which can cause trajectory distortion. The adaptive feedforward controller based on phase angle error is used to solve trajectory distortion problem. Combined with the input shaper and adaptive feedforward control based on phase error, it can solve the vibration suppression of X-axis and Y-axis flexible load with different vibration characteristics, and can guarantee the track accuracy. Finally, the effectiveness of the algorithms is verified by simulation.

The bridge-type amplifier and the lever-type amplifier are the two frequently used displacement amplifiers in the precision engineering. However, to the knowledge of the authors, the analysis and the performance comparison between the two amplifiers was not frequently reported, which is instrumental in realizing and selecting the displacement amplifiers in the practice application. To this end, the two types mechanisms are analyzed and compared with a compliance matrix based model. Via the analysis and comparison, some interesting results which are significant for the amplifiers are founded: 1). The amplification ratio is related to the input displacement when the elastic load is applied; 2) The limited amplification ratio phenomenon is observed in the bridge-type mechanism but also the lever-type one; 3) The comparison of the flexure hinges design for the two amplifiers are presented; 4) The load capacity of the two amplifiers are first analyzed and compared in this paper. Finally, the accuracy of the modeling is verified by FEA simulation studies.
