Autonomous robots in human-robot interaction (HRI) recently are becoming part of human life as the number of services or personal robots increasingly used in our home. In order to fulfill the gap of HRI merit, we would like to propose a system of the autonomous robot motion and grasping creation for assisting the disabled person such as the blind people for handover tasks to help blind people in pick and place tasks. In this paper, we develop the robot motion to receive the object by handing over from the blindfold human to represent the blindness. To determine the target of the object and human hand, we implement the 6DOF pose detection using a point cloud and hand detection using the Single Shot Detection model in Deep learning for planning motion using 9DOF arm robot with hand. We finally experiment and evaluate the tasks from blindfold-robot handover tasks.

Makoto Sakamoto, Takahiro Ishizu, Kenji Sakoma, Takahiro Shinoda, Amane Takei, Takao Ito
Augmented reality (AR)technology is a technique of superimposing information generated by a computer on perceptual information that we receive from real space. Recently, much attention has been focused on interaction techniques between users and virtual objects, such as the user directlymanipulating virtual objects with his/her bare hands. On the other hand, in AR technology, since the 3-dimensional (3D) model is superimposed on the image of the real space afterwards, it is always displayed on the front side than the hand. Thus, it becomes an unnatural scene in some cases (occlusionproblem). In this study, this system considers the object-context relations between the user's hand and the virtual object by acquiring depth information of the user's finger.In the evaluation experiment, it is confirmed that the hidden surface removal in this study not only makes it possible to consider the object-context relations but also can distinguish between finger boundaries and to clarify and process finger contours.

1.Wheeled Mobile Robot Robust Control Based on Hybrid Controller Approach
In this paper, a novel trajectory following method based on hybrid control strategy is proposed for the trajectory following problem of mobile robots with nonholonomic constraints. The mobile robot controller is composed of threeparts: kinematics, dynamics equations and Cerebellar Model Articulation Controller. The control speed needed to realize the reference trajectory tracking is obtained from the motion equation under the position tracking error. The virtual control value of the control speed is obtained by using Lyapunov, and the controller is designed in the dynamic equation. The cerebellar model articulation controller (CMAC) is used to approximate the nonlinearity and uncertainty of the dynamic model of the mobile robot. At the same time, the torque controller is combined with the velocity error to form the torque controller. The influence of the uncertain disturbance on the system is compensated on-line. In the discussion in this paper, the nonlinear system is consider, and the Lyapunov stability criterion guarantees the global stability of the system and the asymptotical convergence of tracking error. The simulation results in Matlab/Simulink environment further verify the effectiveness and superiority of the proposed control algorithm.

Lingran An, Fengzhi Dai, Linghe An
The traditional super-resolution method has limited ability of feature extraction and feature expression, which cannot meet the requirements of high quality image in practical application. This paper mainly applies the relevant theories of deep learning to image super-resolution reconstruction technology. By comparing three classical network models used for image super-resolution (SR), finally a generative adversarial network (GAN) is selected to implement image super-resolution, which is called SRGAN. SRGAN consists of a generator and a discriminator that uses both perceived loss and counter loss to enhance the realism of the output image in detail. Compared with other algorithms, although the improvement of PSNR and SSIM values of the SGRAN network obtained by the final training is not obvious, the output high-resolution images are the best in the subjective feelings of human eyes, and the reconstruction effect in the image details is far higher than that of other networks.

The formation of successful corporate strategy among vertically integrated organizations is predicated upon a plethora of dynamic relationships among buyer-seller firms. Albeit growing in interest, there is a paucity of research that focuses on predicting the nature of interfirm relationships among Japanese keiretsu members. Discerning this knowledge can help formulate successful strategic decisions, such as whether to continue procuring parts or increasing future investments in partner firms. As studies on predicting interfirm relationships among keiretsu member firms has been scant, this research offers insights by illustrating a newer approach for making decisions regarding corporate strategy. Using data collected on transaction from Yokokai—parts suppliers of Mazda—in this study a new model is developed to predict the nature of interfirm relationships using the degree index and DEA model. The primary contribution of this research is that interfirm relationships not only depend on future trends, but are also determined by the interactions among member firms of a keiretsu.
