In this paper, two basic problems are addressed: the selection of the inverse kinematics solution and the generation of the path during the process. An algorithm is proposed to find the appropriate solution of the IK problem. In the proposed algorithm, the continuity and periodicity of joint angles are considered and the final solution is selected by minimizing the Euclidean distance from the current state. The path is generated under the kinematics constraints of the door and the limitation of the work space of the manipulator. The experiments are carried out on a real robot with a 6DoF manipulator and a mobile platform. The experimental results showed that the robot system was able to twisting door handles and pull open doors which also proved the correctness of the proposed algorithm and the path generating method.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116757334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High adaptability and smooth actuation can be realized with compliant materials. In this research, we developed a prototype soft robotic hand using shape memory alloy (SMA) and woven type smart soft composite (SSC). First, the main components and actuation of hand are defined from the anatomy to build soft robotic hand. Then, woven type SSC based actuator is fabricated and tested as an artificial muscle.

Then Random Forest algorithm is employed to be trained as the classifier, by which the weight parameters of the composite feature are obtained simultaneously. Experimental results on 20 different kinds of objects demonstrate that our approach achieves high recognition accuracy with 99.33%.

Considering the issues of the inefficiency, inflexibility and large capability required for motor driver of the traditional inverted pendulum system, the feature of the new inverted pendulum system possesses the advantages of simple structure, quick response, and high efficiency in control. The gyroscopic precession effect of high-speed gyroscopic rotor effectively provides a large torque to realize stable equilibrium of the new inverted pendulum system.

Chemoattractant loaded microsource beads are employed to release the drug to generate gradient field, which induces cell polarization. A new geometric model that formulates the cell to confine within the high motility area while maintaining the microsource bead near the optical trap is established.

By using automatic selection of the control points, performance and precision of motion tracking is improved and it leads to a robust tracking. In addition to increase accuracy and facilitate selection of control points, in proposed method, surgical instruments and specular reflection are detected and eliminated from the image. Finally, a modified version of 3D tracking algorithm based on a Thin-Plate Spline (TPS) deformable model is developed to improve the motion tracking.

This paper investigates human motion recognition based on feature-selected sequential Kinect skeleton data. We extract features from the Cartesian coordinates of human body joints for machine learning and recognition. As there are errors associated with the sensor, in addition to other uncertain factors, human motion sequential sensor data usually includes some irrelative and error features. To improve the recognition rate, an effective method is to reduce the amount of irrelative and error features from original sequential data. Feature selection methods for static situations, such as photo images, are widely used. However, very few investigations in the literature discuss this with regards to sequential data models, such as HMM (Hidden Markov Model), CRF (Conditional Random Field), DBN (Dynamic Bayesian Network), and so on. Here, we propose a novel method which combines a Markov blanket with the wrapper method for sequential data feature selection. The proposed algorithm is assessed using four sets of human motion data and two types of learners (HMM and DBN), and the results show that it yields better recognition accuracy than traditional methods and non-feature selection models.","PeriodicalId":325536,"journal":{"name":"2015 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124240374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
