A simple technique to realize demodulator for linear variable differential transformer (LVDT) is presented in this paper. The proposed LVDT demodulator is based on sample and hold technique. The proposed scheme consists of peak detector, phase detector, monostable circuit, sample and hold circuit, and controllable unity-gain inverting/noninverting amplifier. The presented technique employs the simple and low-cost devices such as op-amp, and digital logic gate. Experimentation with the commercial LVDT model OP12.5G from Solartron metrology shows that the proposed LVDT demodulator provides the output voltage corresponding to the movement of LVDT core with satisfactory values and good linearity. The maximum error of the proposed demodulator is about 1.5%. In addition, the output magnitude of proposed LVDT demodulator can be adjusted by variable resistor (VR1) without the external circuit requirement.

Against recent cyber-attack strategies on networked control systems which commonly utilize information of control data, the notion of encrypted control system has been introduced, to protect private data in the network layer by encryption. However, even though the adversary cannot learn the information from the encrypted control signals or parameters, it is known that their values can be manipulated by the adversaries, based on homomorphic property of the cryptosystem. In this paper, we demonstrate that the injection of zero-dynamics attack is possible even for encrypted control systems. By injecting an attack signal, generated with knowledge of the plant model, directly on the encrypted controller output being transmitted to the actuator, we show that it disrupts the plant state while it is undetectable from the input and output of the controller. Simulation results are presented to demonstrate the effectiveness of the proposed attack.

In recent years, numerous studies have been conducted on the robot grasping using deep learning, which requires a lot of data and training time. This study proposes a grasping algorithm that does not require data collection and training. In addition, the hardware of the proposed system is simply configured for a quick application in industrial fields. This algorithm is performed through clustering and grasping analysis based on point clouds. First, the point cloud obtained from the 3D camera is clustered, and the cluster most similar to the 3D CAD model is selected. Next, using the selected cluster, the object pose and the grasping pose are estimated. Finally, the target object is grasped through the estimated grasping pose, and the grasped object is loaded with a predetermined pose in consideration of the object pose. In order to evaluate the performance of the proposed algorithm, the grasping and loading of the target object with a product used on the actual industrial site and the loading jig of the object were tested. The algorithm showed the success rate of 95% in grasping, transporting and loading experiments.

This paper presents a novel robotic stage for human balance disorder assessment. The proposed robot is composed of top and bottom plates which move perpendicular to each other in x- and y- directions. Both plates can be driven or controlled simultaneously or one at a time. Each of the drive systems for the plates utilize a BLDC motor, ball-screw, force sensor, and motor encoder, which enable various control strategies. Moreover, the force sensor is located between the ball-screw and the load, hence, the load reaction force can be directly measured. To conduct the balance assessment, a human (patient) stands on the top plate of the stage and the robot is driven by either force or position control, from which the force is measured directly by the force sensor. Then, the balance disorder assessment is done by observing the characteristics of the force measurements. This device provides a wider motion strokes which enable the examiner to obtain detailed balance disorder information as compared to the existing techniques. Experiments on both control and actual human balance test are carriedout to verify the effectiveness of the proposed device.

To perform a tidy-up task using a robot arm, it is necessary to estimate the pose of various objects. Generally, pose estimation requires the CAD model of an object, but these models of most objects in daily life are not available. Therefore, this study proposes an algorithm to estimate the pose of unknown objects without the help of CAD models. Furthermore, the strategies on grasping and object manipulation for robotic tidy-up are also proposed. First, the geometric and color information are considered together to segment the various objects in the aligned point cloud. Then, the principal component analysis (PCA) scheme is used to estimate the object frame and the placement state. Based on this estimation, the proposed strategies were introduced to make it possible to tidy up the objects. It was shown from various experiments that the proposed method can be effectively applied to the robotic tidy-up tasks.

This paper presents a simulation result of dynamic reaction forces on the slave-arm revolute joint of the mechanical master-slave manipulator for remote handling of radioactive materials and nuclear processing. The dynamic modeling of the manipulator is established in the multi-body dynamics(MBD) simulation S/W of RecurDyn to verify the gear tooth contact force and bearing reaction forces on the revolute joint of its slave-arm on condition of the maximum handling load. For modeling the detailed parts of the revolute joints , two stages gear transmission; one bevel gear-pair and the other spur gear pair, and two support rolling bearings are defined with mechanical properties. As results of the force analysis, the reaction forces on gearing and bearings which are used to address the improvement of the joint design are shown for the manipulator.

The application of robots to the agricultural sector has significantly improved productivity in the field. Studies investigating various forms of end-effectors are being carried out constantly, especially in relation to the harvests of fruits that require a lot of labor. However, the majority of studies focus on stably cutting the pedicel after accurately recognizing the target, while there is relatively little interest in the method and process of transferring agricultural produce after the harvest. The development of a dedicated end-effector is essential to reduce the duration of the entire procedure, which is a significant goal in harvest-related research. This entails comprehensive consideration of the transfer process. To address this issue, in this paper, we propose an integrated end-effector, which enables almost simultaneous execution of harvesting and transfer of tomatoes. Further, a modular mechanism is introduced to improve the performance of harvesting robots, and future directions of research are outlined.

This paper presents a local path planning algorithm for perpendicular parking of an autonomous vehicle. We propose an optimal path planning algorithm based on circle and line combination in the presence of predefined obstacles. We formulate collision avoidance conditions using equality and inequality constraints. We solve a generalized optimization problem with the constraints, which minimizes an arc-length of the parking path. We validate the performance of the perpendicular parking path generation algorithms for various parking spaces in MATLAB environments.

The use of robotic platforms for operations in harsh and high risk environments such as mining sites has become more popular with the advancements within the field of mobile robotics. In this paper, the designing of a hybrid locomotive mobile platform that utilizes both tracked locomotion and legged-like movements to achieve mobility is presented. The proposed track-leg mechanism and power transmission methodology are discussed in detail along with the overall design framework. The functionality validation and analysis of the legged locomotion was done in a simulation environment using MSC ADAMS with open-loop track-leg velocity control. The designed mobile robot demonstrated the ability to traverse a flat terrain and overcome a semi-cylindrical obstacle without tipping over in the simulations for the selected gait. The mobile robot also consists of 3 degrees of freedom (DOF) robotic arm which facilitates total human replacement by enabling the ability to perform any sample collecting, inspecting, pick and place tasks. The design of the robotic arm is also presented within this paper.
