2009 IEEE/RSJ International Conference on Intelligent Robots and systems

作者： Dapeng Yang Jingdong Zhao Yikun Gu Li Jiang Hong Liu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin Heilongjiang China

The multi-DOF prosthetic hand's myocontrol needs to recognize more hand gestures (or motions) based on myoelectric signals. This paper presents a classification method, which is based on the support vector machine (SVM), to classify 19 different hand gesture modes through electromyographic (EMG) signals acquired from six surface myoelectric electrodes. All hand gestures are based on a 3-DOF configuration, which makes the hand perform like three-fingered. The training performance is very high within each test session, but the cross-session validation is typically low. Acceptable cross-session performance can be achieved by training with more sessions or fewer gesture modes. A fast rhythm muscle contraction is suggested, which can make the training samples more resourceful and improve the prediction accuracy comparing with a relative slow muscle contraction method. For many precise grasp tasks, it is beneficial to the prosthetic hand's myocontrol if we can efficiently extract the grasp force directly from EMG signals. Through grasping a JR3 6 dimension force/torque sensor, the force signal applying to the sensor can be recorded synchronously with myoelectric signals. This paper uses three methods, local weighted projection regression (LWPR), artificial neural network (ANN) and SVM, to find the best regression relationship between these two kinds of signals. It reveals that the SVM method is better than ANN and LWPR, especially in the case of cross-session validation. Also, the performance of grasping force estimation based on specific hand gestures is superior to the performance of grasping with random fingers.

As the endeffectors of micromanipulation systems, microgrippers are crucial point of such systems for their efficiency and their reliability. So the steady and reliable performance of the microgripper is needed. In this work, a hybrid-type electrostatic silicon microgripper integrated vacuum tool is designed and fabricated to realize the steady gripping and reliable placing manipulations. This hybrid-type microgripper keeps the traditional functions of electrostatic comb drive microgripper and also combines the advantages of the vacuum tool. Vacuum tool integrated in this novel microgripper is used to improve its pick and place capability. Bulk micromachining technology is employed to fabricate the microgripper from single crystal silicon wafer. The vacuum control subsystem and electrostatic comb drive control subsystem are also designed for the microgripper controlling. At a driving voltage of 80V, a deflection of 25¿m at the arm tip of the gripper is achieved. The objects ranging from 100¿m to 200¿m are picked and placed successfully in the experiment, and the experiment results indicate that this microgripper can realize the steady manipulation.

Vision-based motion estimation is a key technique in autonomously mobile robot. This paper presents an integrated method for motion estimation of the mobile robot based on floor plane extraction. The whole processes include floor plane extraction, pose estimation of the onboard stereo vision system and motion estimation of the mobile robot. First, based on disparity map obtained from the onboard real-time stereo vision system, a two-stage method is used for fast floor plane extraction. Then all the points belong to the floor plane are transformed from disparity space to Euclidean space, and a simple least squares method is employed to fit the floor plane. The fitting parameters of the floor plane are used for the pose estimation of the onboard stereo vision system. Finally, the motion of the mobile robot is estimated with the tracking results of the points on floor plane. The proposed motion estimation method is intended to be used in the motion control of a wheeled mobile robot. Experimental results in real environments are presented. ©2009 IEEE.

The colonoscope is an important surgical tool to diagnose various colon diseases. However, the conventional colonoscope usually causes the patient a great deal of discomfort and pain. In order to develop a colonoscope for less discomfort of the patient and less demanding operation techniques of the doctor, a novel snake-like robotic colonoscope is proposed in this paper. This robotic colonoscope adopts a kind of continuum structure which features continuously deformable backbone as opposed to the traditional robot featuring rigid links and identifiable rotational joints. The robotic colonoscope is 600mm in total length and 12mm in diameter that is less than the average diameter of human colon. The robotic colonoscope is divided to five sections, and each driven remotely by two DC servo motors through cables. Thus, each section of the robotic colonoscope has 2 DOF (Degrees of Freedom) and the robotic colonoscope has a total of 10 DOF. The mechanical structure, kinematics and DSP-based control system are presented. The workspace simulation and prototype experiments are carried out to verify the kinematics and show the motion performance.

IEEE International Conference on Mechatronics and Automation

作者： Guoliang Zhang Bin Wang Jie Wang Hong Liu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin Heilongjiang Province China

This paper presents research and development for a hybrid visual servoing control method for a newly developed space robot. The hybrid scheme consists of an eye-in-hand camera and eye-to-hand camera configuration. The first one guarantees good accuracy and the ability to explore the workspace; the second one ensures a panoramic sight of the workspace. The motivation of this paper is to take advantage of both in a cooperation scheme to makes the execution of complex tasks easier and offers higher flexibility in the presence of a dynamic scenario. Compared with other multi-camera system, both global and local vision has the capability of determining pose of target independently. Moreover, this paper also addresses suitable object recognition and pose estimation algorithm based on polygonal approximation. To realize real-time visual servoing control, part of recognition module has been optimized to increase process speed. Finally, 3D visual servoing within a dynamic look and move scheme based on estimated object pose has been carried out. Experimental results demonstrate the feasibility and the effectiveness of the proposed method.

The paper deals with the motion of turning in place of a spherical robot for military reconnaissance and unknown environment exploration developed by us. The robot belongs to a nonholonomic and under-actuated system. The robot has 3 DOF and 2 inputs. The motion of turning in place can make a spherical robot with higher dexterity and environmental adaptability. The mathematical model of the turning motion is established by theory of moment of momentum. The relationship between the motion parameters is deduced, which is the basis of motion simulation and control system. Based on the analysis of mathematical model, a stick-slip principle is proposed for turning in place of the robot which is driven by double ballast masses. The stick-slip process is divided to three stages which are interpreted in theory. The principle is verified by numerical simulation and prototype experiment. The results confirm the effectiveness of the principle. The errors between theoretical analysis and experiment are analyzed at last.

A controllable flexible biomimetic fin actuated by Shape Memory Alloy (SMA) was presented to imitate the flexible bending of fin rays in bony fishes. Based on the bending experiment of the biomimetic fin, the kinematics model was set up. Then a two-dimensional numerical simulation on the oscillatory biomimetic fin was performed by computational fluid dynamic to investigate the interaction with the surrounding fluid and the propulsive force production. By solving the 2D, incompressible, laminar, unsteady Navier–Stokes equations, the computational results show that the biomimetic fin generates a vortex ring after a complete period in still water which can generate a thrust force. The dynamics performance of the vortex ring is achieved and then the average propulsive force is calculated on different oscillatory frequencies and maximum bending angles to find the change character. At last, an important parameter, the Strouhal number was discussed in this paper. Different Wake pattern were observed depending on different velocities of the background flow, which decide the Strouhal number. When the 0.2

A ring type standing wave USM using bending transducer is proposed. The transducer includes one exponential horn located on leading end,and the horn insect with the ring at tip end. The working principle of proposed motor is analyzed. The ring and transducer are designed with FEM. The bending vibration modals of ring and transducer are degenerated. Transient analysis is developed to gain the vibration characteristics of stator,and results indicate that the motion trajectories of nodes on the teeth are oblique lines. Results also indicate the proposed design enables the standing wave USM to operate with large vibration amplitude,which would improve the mechanical output characteristics. The results of this paper verify the theoretical feasibility and provide instructions for the development of proposed motor.
