In this paper, the mobile robot equipped with a single ultrasonic sensor to measure the value of the distance between the mobile robot and the obstacle will be manipulated by a haptic joystick through the value of Force Feedback. Accordingly, the mobile robot will move based on the information of the ultrasonic sensor without colliding the obstacle to precise velocity control. Vibration part which is designed and installed at the bottom of the joystick implements Haptic features using the distance data from the ultrasonic sensor. Using the Bluetooth communication, the haptic joystick and the mobile robot give and receive the data mutually to control the mobile robot's velocity. In order to realize the precise velocity control, PD controller with the advantage of stabilization system is designed and the performances of two cases before or after PD control are evaluated and compared.

Generally, stray capacitance is unnecessary element of designing circuit, because it can not be predicted by a designer. But we propose LC Resonant Circuit using stray capacitance of transformer. This method proposes miniaturization of circuit, because LC Resonant Circuit can be make simply to using stray capacitance instead of capacitor and size of transformer is reduced. Finally, we research aspect of dielectric heating by change of frequency and output voltage using developed converter.

This paper investigates passivity-based pose control via an obstacle avoidance navigation function for three-dimensional (3-D) eye-in-hand visual feedback systems. Firstly, visual motion observer-based pose control for 3-D eye-in-hand visual feedback systems is presented. Next, a path planner to be appropriate for the visual motion error system is designed through an obstacle avoidance navigation function to keep collision-free during servoing. Finally, the effectiveness of the proposed method is verified through computer simulations.

This paper investigates stabilizing receding horizon control via an obstacle avoidance navigation function for three-dimensional (3-D) eye-to-hand visual feedback systems. Firstly, a visual motion observer for a controlled mobile robot is presented. Then, visual motion observer-based stabilizing receding horizon control for 3-D visual feedback systems, highly nonlinear and relatively fast systems, is proposed. Moreover, a path planner to be appropriate for the visual motion error system is designed through an obstacle avoidance navigation function to keep collision-free during servoing. Finally, the effectiveness of the proposed method is verified through computer simulations.

Data-driven fractional PID control: application to DC motors in flexible joints

IFAC Proceedings Volumes 2012年第3期45卷 709-714页

Recent advances in data-driven (or model-free) control have permitted to enhance the closed loop behavior of linear and especially nonlinear systems using very simple control structures. As a result, unknown or badly known dynamics are compensated and disturbances are rejected without any learning or on-line identification procedure. However, the ultra-local phenomenological models on which this control technique rely have not yet exploited the fractional nature of many processes and the nonlocal nature of the fractional integrodifferential operators. In this paper, fractional derivatives are used in the so called model free control structure in order to explore the advantages they provide in terms of robustness and dynamic response. Fractional and integer order data driven PIDs will be compared for a DC motor in a robot flexible joint control application in a simulation environment.

This paper evaluates existing taxonomies aimed at characterizing the interaction between robots and their users and modifies them for health care applications. The modifications are based on existing robot technologies and user acceptance of robotics. Characterization of the user, or in this case the patient, is a primary focus of the paper, as they present a unique new role as robot users. While therapeutic and monitoring-related applications for robots are still relatively uncommon, we believe they will begin to grow and thus it isimportant that the spurring relationship between robot and patient is well understood.

Micro Aerial Vehicles (MAVs) have gained a significant amount of research lately, with a number of universities and industry sponsors paving the way with micro flying robots to perform Intelligence, Surveillance and Reconnaissance (ISR) Missions. However, much of the work done in flapping wing MAVs till date has not shown performance improvements over their Vertical Take Off and Landing (VTOL), rotary-wing counterparts. Research and development over the years has shown that insects and birds have unmatched flying capabilities in the Low Reynolds Number Regime. Their phenomenal flight performance is attributed to among others the highly energy efficient actuation systems and their power to weight ratios. The paper proposes and illustrates new and energy-efficient actuation mechanisms and incorporating them into MAVs. The paper begins by elaborating on the background of our research and the need for energy efficiency in MAVs;followed by showcasing resonant, elastic/restorative actuation mechanisms and their control methodology to reduce flight-actuation energy requirements. In conclusion, the paper contrasts and compares all the actuation systems for power intake, scalability and mechanical complexity.

This paper investigates open-loop control, which does not need the joint angles and velocities, for two degree of freedom(2DOF) robot manipulators with antagonistic bi-articular muscles which are passing over adjacent two joints and acting the both joints simultaneously. The manipulator dynamics of three muscle torques, we call the bi-articular manipulator dynamics, is constructed in order to design the control input. Stability analysis with respect to our proposed control law is discussed based on the Lyapunov method. Our approach is inspired by the fact that humans do not measure the joint angles and velocities explicitly, Finally, simulation results are shown in order to confirm the proposed method and given a design procedure in order to assign the tuning parameter.

In this paper, PDR system's Improved performance and height estimation are introduced using a low-cost IMU. The personal navigation systems typically have used GPS. But the area where GPS signals are blocked should not be used such as indoor environments. To compensate for this, one of a technique is used PDR system. The location of a pedestrian estimates using only PDR system of the IMU. First of all, in order to estimate the location, a low-cost sensor corrected and manufactured the module. The step is detected using acceleration information by moving of the pedestrian through the module. A step length can be estimated using the detected step. The position estimation and heading will be estimated by the acceleration sensor and gyro sensor. Finally, information of the acceleration sensor and barometer applied to the KF (Kalman Filter) to estimate the height. This paper was tested in a real-environment based on the proposed algorithm. As the result, excellent performance was confirmed within the average distance error within 1% and the position error within 4% in the location estimate. And the results of height estimate, average standard error is confirmed improved performance as max 0.15m in case of using Kalman Filter.

As the number of mobile robot applications increases, research related to physical contact between humans and robots is becoming an important issues in the service robot domain. In this paper, a mobile robot platform based on spring loaded casters is proposed as solution to problems in the service robot domain. A simple dynamic equation in two dimensions was computed and the dynamic characteristics according to variation of the elastic coefficient were analyzed. In order to detect force from a human, a linear equation was formulated by regression of the driving data. With the estimated force, an impedance model is applied to the controller for compliance. Through this process, it is shown that the proposed mobile robot platform is capable of a compliant reaction to external force through of its posture, similar to unstable mobile platform, though the mobile platform has the static stability. © 2011 IEEE.
