In this paper, we proposed a position-based control strategy for eliminating the vibration at the end of deformable linear objects (DLOs) during its manipulation. Using Schur decomposition of matrices and linear transform of variables, actuated and underactuated parts of the DLO dynamic model are separated. Based on the decoupled dynamic model of a DLO system, a sliding mode control with exponential approach law is designed to force the state variables to converge to an equilibrium and to allow vibration at the end of the DLO to be damped quickly. The DLO system, subjected to control input saturation, is further studied to solve the input saturation problem. An adaptive sliding mode control law is designed to suppress the damping at the end of the DLO. Proposed control strategies are verified by numerical simulations. The simulation results show that proposed methods can effectively damp the vibration at the end of the DLO.

Computed tomography (CT) fluoroscopy is a useful imaging modality for guiding various interventional procedures (e.g., ablation, biopsy, and drainage). However, radiation exposure is a major disadvantage of CT fluoroscopy guidance. Even if a physician uses 17-cm forceps, radiation exposure to their hand is 7.0 µGy/s (120 kV; 30 mA). The average activation time for CT fluoroscopy in a lung biopsy has been reported to be approximately 90 s. It is expected that the activation time would be longer for more complex procedures such as ablation for large tumors. Therefore, radiation exposure during CT fluoroscopy is a serious concern for physicians.<BR>Robotic surgery, which is the preferred surgical method for 80% of prostate cancer surgeries in the United States, has been shown to reduce procedural complications. We hypothesized that robotic technology might be more easily applied to CT-guided interventions. If physicians performed CT-guided interventions using a robot that they controlled from a location far from the CT gantry, radiation exposure to physicians could be minimized. However, issues such as metal artifacts and the limited workspace may hinder the development of a robot for CT-guided interventions. More specifically, the robot must be constructed of non-metal materials and it must fit in a small space within the CT gantry. Despite these limitations, we have developed a prototype model of the robot.<BR>The prototype has 5 degrees of freedom and can be remotely operated with a joystick controller. Phantom experiments using the prototype showed no radiation exposure to the operating physician during the procedure. In this article, we will provide an overview of the development of this prototype model, present the limitations of the prototype, and discuss future prospects.

Traffic problems such as pollution and congestion are becoming more and more serious in urban areas. A potential solution to these problems is to develop narrow vehicles that occupy less space and have lower emissions. There has been increasing interest in underactuated mechanical systems, i.e., mobile wheeled inverted pendulum (MWIP) models, which are widely used in the field of autonomous robotics and intelligent narrow vehicles. A novel narrow vehicle based on an MWIP and a movable seat, called UW-Car, is investigated in this paper. The dynamic model of the underactuated vehicle system running on flat ground is derived by Lagrange's equation of motion. Based on the dynamic model and terminal sliding mode control method, two terminal sliding mode controllers are designed to control velocity and braking of the UW-Car. The first one is used to control the forward speed to a desired value while keeping the body upright and the seat on some fixed position. The second one is a switching sliding mode controller, composed of three terminal sliding mode controllers that quickly brakes the system according to an optimal braking scheme. All the control algorithms are tested in both MATLAB simulation and a UW-Car experiment. The simulation and experimental results demonstrate the efficiency of the model and controllers.

This paper proposes a design method of extended self-tuning generalized predictive control (GPC) with computation reduction focused on closed-loop characteristics. The authors have extended GPC by coprime factorization and proposed the extended controller for constructing a strongly stable system. Moreover, the proposed controller is able to be designed to make the same steady state output as pre-designed system's steady state output even if feedback loop is cut. Although self-tuning controller is one of the control methods for systems with uncertainty, there is a problem that the computation of self-tuning GPC increases as design engineer takes long prediction horizon in the design parameters. Therefore this paper considers computation reduction for extended self-tuning GPC focused on closed-loop characteristics. The validity of the proposed method is shown by numerical simulation. © IFAC.

Traffic problems such as pollution and congestion are becoming ever more serious in urban areas. A potential solution to these problems may be the development of narrow vehicles, which occupy less space and produce fewer gas emissions. There has been increasing interest in these types of underactuated mechanical systems, such as Mobile Wheeled Inverted Pendulum (MWIP) models, which are widely used in the field of autonomous robotics and intelligent narrow vehicles. A novel structure based on an MWIP and a movable seat above called the UW-Car is investigated in this study. Dynamic models of this underactuated vehicle running on flat ground and in rough terrain are derived using Lagrange's motion equation. Based on the models and the Terminal Sliding Mode Control (TSMC) method, two terminal sliding mode controllers were designed for the velocity and braking control of a UW-Car. The first one is for heading speed to a set-point while keeping the body upright and the seat in some fixed position. The second one is a switching sliding mode controller made up of three terminal sliding mode controllers. By using the proposed controller, a UW-Car can move at a desired velocity while keeping the seat always upright. To solve the problem of obtaining quick acceleration performance in a UW-Car, a control method combining trajectory generation and dynamics canceling inputs is proposed. Using this method, the UW-Car can achieve high acceleration while keeping its body upright at all times. All the proposed theoretical results are finally demonstrated through numerical simulations. © 2014 Elsevier Inc. All rights reserved.

Flying object used in our research is an experimental device like a helicopter. Helicopter, which has a special characteristics such as hovering, vertical ascent and vertical dive. Therefore, it is widely used at the time of disaster. For example, manned helicopter is used for rescue work, emergency transport and fire fighting. On the contrary, unmanned helicopter is used to get precious information in a danger area for human. But there are problems that the structure is complicated, it has a high nonlinearity. And it is difficult to keep the attitude, because it is influenced by wind in flight. An experimental device in our research has an underactuated system having 2-input and 3-output that has number of input less than number of output. So, this system is able to reduce cost, but to keep the posture is difficult. Therefore, in our research, a stabilization method called two degree-of-freedom PID control has been proposed. It is the system having three degree-of-freedom. Although the effectiveness has been confirmed through the simulation and experimental results in time-domain, the characteristics of the proposed method was just explored by the result of output for step-type reference signal. Therefore, this paper confirms the effectiveness of the proposed method through the simulation and experimental result in frequency-domain in order to check the characteristics of the proposed method.

A lot of researches on inverted pendulum cart are conducted in recent years. And it is attracted as a personal vehicle which realizes energy saving for many practical applications, such as the Segway and the P.U.M.A. The personal mobility has the advantage of energy efficiency for transportation because the cart is small and light. However, since most conventional personal vehicles require a certain level of physical ability from the driver, it is not suitable for elderly and disabled people to drive. Therefore, an inverted pendulum cart with a sliding mechanism for posture control is developed as a personal mobility available for anyone. And we aim for realization of acceleration and deceleration while keeping the angle of the cart perpendicular. In this research, proposed inverted pendulum cart with a sliding mechanism for posture control was designed and manufactured, and the posture control performance was verified through experiment.

Language：Japanese Publisher：The Robotics Society of Japan

Fault detection functions of a robotic manipulator are very useful for factory automation. All production has the possibility to fail due to unexpected accidents. To reduce the fatigue of human workers, small errors automatically should be corrected by a robot system. In this paper, an external thread fastening task by a robotic manipulator is investigated. To discriminate the four states of a task, linear support vector machine methods with two feature parameters are introduced. One is the estimated insertion length, and the other is the maximum reaction force. The effectiveness of the proposed algorithm is confirmed through an experiment and recognition examination.

In realizing a robotic assembly system of electronic products, recognizing the connectors with flexible cables as a single component is one of the most difficult problems, which prevents from automating the system. To overcome this problem, we used our proprietary 3-D range sensor and developed three component algorithms: one is to recognize randomly-stacked connectors; another is to automatically compensate rotational and positional errors by force sensor; the other is to set up visually-guided offline developing environments. In this paper, we introduce these component algorithms and their integration into an evaluation system in detail. © 2011 IEEE.
