Recently, industrial robots have engaged in various works. In the near future, robots will be required to work out some difficult assemblies instead of human. Even though high sensitivity of force sensor is needed for difficult assemblies, it is inferior to that of human. Therefore, a force sensor should be developed so that sensitivity can catch up with that of human. In conventional research, some researches concerned with force sensors are conducted. However, they do not have both wide range and high durability. In this paper, we propose a tuning fork structured piezoelectric vibration sensor. It is possible to realize both of high sensitivity and high durability due to multi vibration mode. Through the FEM results, we developed prototype sensor which has two feasible vibration modes. And it applied for robot control in order to confirm the availability. © 2011 IEEE.

Jian Huang, Pei Di, Toshio Fukuda, Takayuki Matsuno

IEEE TRANSACTIONS ON CONTROL SYSTEMS TECHNOLOGY 18 ( 5 ) 1207 - 1215 2010.9

Language：English Publishing type：Research paper (scientific journal) Publisher：IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC

Mating a pair of electric connectors is one of the most important steps in a robotic wiring harness assembly system, which can be modeled by static piecewise affine (PWA) systems. To design a fault detection system for this application, a set-membership approach for static PWA systems is proposed, in which parallelotopic approximation of feasible parameter sets is adopted. An online algorithm is obtained to estimate bounds of uncertain transition points of the PWA model. Based on the estimation, a robust online fault detection algorithm is proposed. The robustness and sensitivity of the algorithm are analyzed. The effectiveness of these methods is finally confirmed through experiments.

IEEE TRANSACTIONS ON ROBOTICS 26 ( 4 ) 750 - 758 2010.8

Language：English Publishing type：Research paper (scientific journal) Publisher：IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC

There has been increasing interest in a type of underactuated mechanical systems, mobile-wheeled inverted-pendulum (MWIP) models, which are widely used in the field of autonomous robotics and intelligent vehicles. Robust-velocity-tracking problem of the MWIP systems is investigated in this study. In the velocity-control problem, model uncertainties accompany uncertain equilibriums, which make the controller design become more difficult. Two sliding-mode-control (SMC) methods are proposed for the systems, both of which are capable of handling both parameter uncertainties and external disturbances. The asymptotical stabilities of the corresponding closed-loop systems are achieved through the selection of sliding-surface parameters, which are based on some rules. There is still a steady tracking error when the first SMC controller is used. By assuming a novel sliding surface, the second SMC controller is designed to solve this problem. The effectiveness of the proposed methods is finally confirmed by the numerical simulations.

Low-Ground-Pressure Vehicle for Landmine Detection : Characteristic of Low-Ground-Pressure Tire and Proposal of Position and Posture Control Technique

FUKUDA Toshio, SATO Shinsuke, HASEGAWA Yasuhisa, MATSUNO Takayuki, ZYADA Zakarya

Transactions of the Japan Society of Mechanical Engineers C 74 ( 744 ) 2038 - 2044 2008.8

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

This paper proposes a kinematic model of the vehicle with low-ground pressure tire that enables to enter a minefield in order to scan remaining landmines by a ground penetrating radar in level III survey. The low-ground-pressure tire makes low pressure contact with a ground by deforming its shape of the tire, but the deformation deteriorates position and steering control accuracy. Therefore this paper models the kinematics of the low-ground pressure vehicle based on experimental results. Besides we experimentally confirmed that the vehicle could precisely trace the target trajectory by considering its kinematics in simulated minefield.

Language：Japanese Publisher：公益社団法人精密工学会

On a two-dimensional jumping behavior by a multi-link mechanism, a mechanism that imitated a animal's leg and a mechanism of conventional robot were compared analytically. Each joint of a conventional robot is independently controlled. On the other hand, because animal's leg has bi-articular muscle, the adjoining joints are not independent. The animal's leg mechanism was imitated by using the closed link mechanism with the rod which connects two joints. For the mechanism which imitated animal's leg and the mechanism of conventional robot, under the ideal condition, each joint torque for stabilized jump ware deduced. On the conventional robot, it is necessary to detect the center of gravity, and to be feedback. By contrast, in the mechanism which imitated the animal's leg, it does not need to feedback the position of center of gravity. Furthermore, four-legged jump robot with the mechanism which imitated animal's leg was produced, and the effectiveness of that mechanism was confirmed by an experiment.

Language：English Publishing type：Research paper (scientific journal) Publisher：IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC

Mating a pair of electric connectors is one of the most important steps in a robotic wiring harness assembly system. A class of piecewise linear force models is proposed to describe both the successful and the faulty mating processes of connectors via an elaborate analysis of forces during different phases. The corresponding parameter estimation method of this model is also presented by adapting regular least-square estimation methods. A hierarchical fuzzy pattern matching multidensity classifier is proposed to realize fault detection and diagnosis for the mating process. This classifier shows good performance in diagnosis. A tyical type of connectors is investigated in this paper. The results. p. P can easily be extended to other types. The effectiveness of proposed methods is finally confirmed through experiments.

Ground Penetrating Radar (GPR) is a promising sensor for landmine detection, however there are two major problems to overcome. One is the rough ground surface. The other problem is the distance between the antennas of GPR. It remains irremovable clutters on a sub-surface image output from GPR by first problem. Geography adaptive scanning is useful to image objects beneath rough ground surface. Second problem makes larger the nonlinearity of the relationship between the time for propagation and the depth of a buried object, imaging the small objects such as an antipersonnel landmine closer to the antennas. In this paper, we modify Kirchhoff migration so as to account for not only the variation of position of the sensor head, but also the antennas alignment of the vector radar. The validity of this method is discussed through application to the signals acquired in experiments.

We propose a brachiation robot named Brachiator. Brachiator is able to swing like a real gibbon. The limbs of Brachiatior are designed to be actuated through the wires. However, the elongation and slack of the wires often arise and make it difficult to estimate the joint angles accurately, which has to be resolved to attain more stable brachiation behavior. In this paper we indroduce a vision system to improve brachiation behavior in real time. A stereo vision system is mounted on Brachiator that looks like a gibbon's face. We estimate errors between a model based trajectory and a real trajectory in implementation world from the images which the vision system captures during the brachiation behavior. Based on the vision-based error estimation as to the grasping position on the target branch, the trajectory of the behavior is adjusted in real time in order to realize successful brachiation behaviors. Experimental results showed that the proposed system reduced deviation of the grasping position of brachiation behavior as much as 40% compared with previous methods.

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

Ground Penetrating Radar (GPR) is a promissing sensor for landmine detection, however there are two major problems to overcome. One is the non-planer (e.g. rough and/or undulating) ground surface. It remains unremovable clutters on a sub-surface image output from GPR. Geography adaptive scanning is useful to image objects beneath non-planer ground surface. The other problem is the distance between the antennas of GPR. When imaging the small objects such as an antipersonnel landmine buried in shallow depth, it increases the nonlinearity of the relationship between the time for propagation and the depth of a buried object. In this paper, we modify Kirchoff migration so as to account for not only the variation of height and pose of the sensor head, but also the antennas alignment of the vector radar. The validity of this method is discussed through application to the signals acquired in experiments.

Quadruped Walking by Joint-interlocking Control Based on the Assumption of Point-contact : Comparison between Pace Gait and Crawl Gait Based on the Energy Consumption

ASANO Yoshihiko, DOI Masahiro, HASEGAWA Yasuhisa, MATSUNO Takayuki, FUKUDA Toshio

Transactions of the Japan Society of Mechanical Engineers C 73 ( 725 ) 230 - 236 2007.1

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

This paper proposes a control algorithm for pace gait of a quadruped walking robot, using a passive dynamics autonomous control algorithm (PDAC). The PDAC realizes an efficient motion based on the intrinsic dynamics of a robot. This paper first calculates an energy consumption of the pace and a crawl gait at various walking parameters such as a stride length and a walking period. The optimal walking parameters are obtained for each gait at various walking speed in the simulation and their parameters are confirmed by applied to an experimental walking robot. The trend of the energy consumption transition measured in the experiments are similar to those in the simulation. For example the consumption energy of the pace gait becomes less than that of crawl gait when a walking speed becomes relatively high. As a result, quadruped walking parameters corresponding to the desired walking speed such as the type of gait, the stride length and the walking period are designed on the energy-consumption-basis.

Transactions of the Japan Society of Mechanical Engineers C 72 ( 722 ) 3302 - 3309 2006.10

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

We propose tailor-made multilayer piezoelectric actuators (TAMPA) having large displacements and large forces. In existing piezoelectric actuators, production of small, low-cost actuators having large displacements and large forces is difficult to achieve. We solved this problem by combining two bimorph-type piezoelectric elements with both ends simply supported, and stacking several elements on top of each other. Moreover, TAMPA is a tailor-made actuator whose displacement to force ratio can be varied widely by adjusting the size of the bimorph-type piezoelectric elements even when the total size of the actuator is kept constant. In this study, the bimorph-type piezoelectric element was analyzed, and the relationship between the displacement and the force under fixed conditions was experimentally determined. The relationship between the displacement and the force of TAMPA was theoretically derived. The analytical results showed that a TAMPA having dimensions of approximately 10×10×10mm is capable of generating displacements of several hundred μm or the force of several N. A prototype was produced and its performance was evaluated. These results agreed well with the analytical results, confirming the validity of the analytical results. Finally, because the lead in PZT can cause environmental problems, a TAMPA was produced that used (K, Na) (Nb, Ta) O_3 piezoelectric ceramics instead of lead.

The essential challenge in the future ubiquitous networks is to make information available to people not only at any time, at any place, and in any form, but with the right thing at the right time in the right way by inferring the users' situations. Several psychological experiments show that there are some associations between each user's situations including the user's emotions and each user's task selection. Utilizing those results, this article presents a situation-based task selection mechanism that enables a life-supporting robot system to perform tasks based on the user's situation. Stimulated by interactions between the robot and the user, this mechanism constructs and updates the association between the user's situation and tasks so that the robot can adapt to the user's behaviors related to the robot's tasks effectively. For the user adaptation, Radial Basis Function Networks (RBFNs) and associative learning algorithms are used. The proposed mechanism is applied to the CRF3 (Character robot face 3) system to prove its feasibility and effectiveness. (c) 2006 Wiley Periodicals, Inc.

Language：English Publishing type：Research paper (scientific journal) Publisher：IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC

Using a topological model and knot theory, we propose a method for describing the condition of a rope. We also propose a recognition method based on the image information obtained from the charge-coupled device cameras to obtain the structure of the rope when manipulated by a robot. This method will help solve the difficulties of robots manipulating deformable objects by providing a theoretical framework of error recovery for deformable object manipulation. We confirm the effectiveness of the methods through experiments.

Control of the Lateral Motion in Biped Walking Based on the Assumption of Point-contact

DOI Masahiro, MATSUNO Takayuki, HASEGAWA Yasuhisa, FUKUDA Toshio

Transactions of the Japan Society of Mechanical Engineers C 72 ( 718 ) 1832 - 1839 2006.6

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

This paper proposes the novel control method named Passive Dynamic Autonomous Control (PDAC). PDAC is based on the following concept which Grizzle et al.^<(6)(9)> employed previously : 1) point-contact 2) Virtual constraint. Point contact means that the contact state between a robot and the ground is point. This makes it possible to generate the robot motion based on the robot inherent dynamics although it becomes difficult to control. Virtual constraint means that all robot joints are connected and interlocked. We present the new approach by means of these concepts to express the whole robot dynamics an an 1-dimensional autonomous system. Due to autonomy, this approach has two following notable points : 1) period from foot-contact to next foot contact can be obtained 2) there is a conservative quantity to make it possible to stabilize the motion. As the first step of realization of 3 D dynamic walking, this paper applies PDAC to the lateral motion and builds the controller. In addition, the stabilization and motion period control are reported. The validity of these control is confirmed by experiment and desired lateral motion is realized.

There are many deformable objects such as papers, clothes, and ropes in life space of a person. Robots need skills to manipulate deformable objects, in order to take active parts in such space. However, it is difficult for robots to manipulate deformable objects well and possibility of failure to operate deformable objects cannot be denied. Therefore, shape recognition method for deformabte object manipulation is required, that has hyper degrees of freedom structures. Thus in this paper, we propose a description method of conditions of rope using a topological model and knot theory. And, we also propose a recognition method to obtain the structure of rope from sensor information through the CCD cameras when a robot manipulates a rope. The effectiveness of recognition method against a method using three-demensional data is verified through an experiment.

In this paper, we propose a description method of conditions of rope using a topological model and knot theory. And, we also propose a recognition method to obtain the structure of rope from visual information obtained by the CCD cameras when a robot manipulates a rope. There are many deformable objects such as papers, clothes, and ropes in life space of a person. Robots need skills to manipulate deformable objects, in order to take active parts in such space. However, it is difficult for robots to manipulate deformable objects well and possibility of failure to operate deformable objects cannot be denied. Therefore theoretical framework of error recovery for deformable object manipulation is required. For error recovery system, it is necessary to abstract profitable data from deformable objects, which are hyper degrees of freedom structures. Finally, effectiveness of methods are confirmed by experiments. © 2005 IEEE.
