Although how to perform tasks at disaster sites has been actively discussed, there is little debate on important issues such as how to deliver robots to disaster sites. We propose to drop a humanoid robot with a parachute from an airplane as one of the methods of delivering robots. In this research, we aim to establish a method to absorb the shock at the time of landing by whole body motion for preventing the damage to the robot. As an early stage of this research, drop tests using a small one-legged robot were conducted. From the viewpoint obtained by these experiments, we designed a parachute landing motion for the small robot heuristically and succeeded in reducing the impact force to 40%.

This paper reports the potentiality of a semi-permanent integrated power source mounted on an insect. First, an insect biofuel cell(BFC) based on trehalase and glucose oxidase reactions which oxidize β-glucose obtained by hydrolyzing trehalose found in cockroach hemolymph(CHL) was developed and the maximum power density of 46 μW/cm^2 was obtained. Then, a self-circulation system of CHL powered by the dorsal vessel of a cockroach was developed for self-refueling of an insect-mountable BFC and connected to a cockroach with a flow channel. Finally, the electrochemical reaction of the anode was confirmed to take place when the chamber was mounted onto the cockroach. The results have enough potential to be applied for a micro battery of novel ubiquitous robots such as insect cyborgs in near future.

This study shows the possibility of plaque detection by near-infrared hyper spectrum imaging (NIR-HSI) and machine learning without plaque stain. While the plaque stain shows where the plaque is, the plaque stain leaves color and may cause anaphylaxis. Near-infrared images are obtained from the plaque cultured teeth by NIR-HSI. RGB images of stained teeth are obtained and superimposed on the near-infrared image. The G channel of the RGB image is corrected to label the spectral data plaque or no plaque. Learning and prediction were performed by Artificial Neural Network. The proposed method showed that plaque could be detected without staining about 70% accurate.

Several observational studies suggest that the infant vocalization towards language acquisition develops through interactions with caregivers. However, what kind of underlying mechanisms works and how caregiver's behavior affects on this process have not been made clear since it is very difficult to control the infant vocalization. In order to attack this issue, we built an infant-like vocal robot "Lingua" as a controllable vocal platform. Lingua has two features; infant-like voice and high articulation capability. The shape of its vocal tract resembles that of a 6-monthold infant based on the anatomical data, and this may contribute to the former. 7-DOFs for articulation in the tongue is realized by sophisticated design of linkage mechanisms inside miniaturized vocal tract for high capability of its articulation. Preliminary experiments showed that the robot succeeded in vocalizing almost the same fundamental frequency vowel-like utterances similar to that of an infant.

This paper describes a concept and implementation of cone-shaped scanning LIDAR for mobile robots. It makes laser lines to scan from the top of a mobile robot for covering the whole robot body and measuring the floor shape. This concept enable mobile robots to detect terrain shape with superior and constant density. In addition, it can be used for safety sensor because the laser beams cover the robot to detect upcoming obstacles or human beings. An implementation and evaluation with a cone shaped mirror are shown.

In this paper, we develop a three-legged robot without a brain. This tripedal walking robot generates gait patterns adaptively and autonomously with no sensor, or controller. The key of this adaptability is to utilize a “weakness” of low-torque motors in each leg. Each motor drives leg joint and adjusts its own phase in response to a reaction force from the ground. As a result of the dynamics of body–motor–environment interaction, the weak motors sync each other.

A large number of injuries were occurred in Japanese school environments. To prevent school injuries, it is important to understand accident situations and prioritize intervention targets. However, it is difficult for a risk manager of each school to do this since each school does not have data enough for statistical analysis. In this study, we developed the system that allows to grasp serious accident situations by integratively utilizing data distributed in multiple schools. The developed system finds serious accident situations that a school risk manager should know as follows. First, the system registers situational feature vectors for accident situations data by using a textmining technology. Second using the database, it searches accidents situations similar to the actually occurred situations. Finally it shows most expensive accidents using medical cost data. The effectiveness of the system was confirmed using 5,817 school injury data.

Robots are expected to play an important role in social welfare and service for older citizens. These robots are required to generate embodied interactions for greetings in order to be able to smoothly coexist and cooperate with humans. A hug motion is one of the important embodied interactions. Therefore, in this study, we develop a hug motion generation model based on analyses of human hug motions. In this model, a hug motion of a robot is generated by using a bell-shaped and a wave-shaped velocity pattern in which accelerations and velocities have smooth changes. As a result, this model can generate a hug motion similar to motions of humans.

As one field of sports, there is a game of bike trial. Riders operate mountain bicycles with various advanced techniques. The purpose of this research is to create a bike trial robot that can operate a mountain bicycle and perform various maneuvers such as bike wheelie and etc. The bike-trial robot is able to clear level differences and ditches which other wheeled type robots cannot clear such obstacles and also cannot intrude into narrow spaces. Therefore, it is possible to use the bike-trial robot in the way of means of mobility for disaster sites. In this paper, in order to verify whether the robot can do Wheelie, it is studied that the robot model is created and simulated of wheelie in simulation soft. And, the prototype physical model of bike-trial robot for experiments is designed and constructed on a scale of two to five.

Recently, it becomes very important to make the environment of handicapped people in the daily life more comfortable and there are many rising movements and activities to fulfill the subject. As a result, the occasion and the field where handicapped people can exercise their ability are increasing. But it is very difficult for them to play such as the wind instruments freely, because such performance needs very skillful and delicate movements of their body parts. In this research, we assume that a professional sax player became unable to use his lips to make good embouchure because of the lack of the lip muscle force and unable to play the saxophone properly. The research object is that we should develop an easily controllable device to make artificial embouchure and the device should enable the player to play the saxophone as before.

This paper proposes a hierarchical model which is composed of a slow feature analysis (SFA) network to extract multi-modal representation of a humanoid robot. The experiment with humanoid robot shows that the network can integrate multi-modal information and detect semantic features by the extraction of the slowly varying features from the high-dimensional input sensory signal, and it shows that the multi-modal representation is useful as state representation for reinforcement learning compared with using state representation without the integration of the multi-modal information.

Recently, cleaning robots are becoming widely used. However, even if commercially-available cleaning robots can collect dust and small debris on the floor, they can not pick up trash such as PET bottles, cans, etc. We developed a cleaning robot intended for picking trash while dust collecting. This paper describes the architecture of the cleaning robot consisting of hardware such as an RGB-D sensor, a robot arm and a commercially-available cleaning robot, and also software for trash picking such as searching trash from RGB-D image, picking the trash via the robot arm and controlling the cleaning robot. We used commercially-available hardware and open source software such as Robot Operating System (ROS), Point Cloud Libraly (PCL) and so on.

Harvesting is a hard work among farm works. Although one of means to reduce time and effort is automation, there are very little examples of automation for crops which are harvested carefully and politely. In case of harvesting such crops, moving obstacles such as leaves out of the way or holding a branch is required. We propose a dual-arm harvesting robot which can do such tasks. Moreover, we focus on a cherry. Holding a branch is required while pulling a cherry's pedicels to harvest a cherry. This paper describes a dual-arm robot which can hold a cherry tree's branch while harvesting cherries.

3D printers are becoming popular and using in many scenes. They enable to make products simply and rapidly according to the design models. However, they can make only a single bulk parts at a time in general. If we can make a whole robot structure at once by 3d printer, it became possible to manufacture a desired robot on the spot in a minute. In this report, we propose a method for making a robot structure including joints at one time by a Fused Deposition Modeling (FDM) type 3D printer. It is unnecessary to assemble after printing. Further, we produced a wire-driven quadruped walking robot as an example of the proposed method.

It is difficult to obtain stable motion arm movement only using a feedback controller because this method must use high gain feedback to achieve accurate motion in early stage of learning. Therefore, motion learning mechanism of human being's arm is explained by both feed-forward controller using internal-error learning method and visco-elasticity adaptation mechanism. This study applies this assumption to both muscle potential and its frequency characteristics show possible verification of visco-elasticity adaptation mechanism.

In order to develop useful assistive devices, it is necessary to analyze and understand the function of human. In this study, the activities of daily living were recorded and the performance of dominant and non-dominant hand was classified according to ICF (International Classification of Functioning, Disability and Health) approved by WHO. As a result, it was revealed that the use of both hands makes a great difference. It will be reasonable to design assistive devices such as prosthetic hands for non-dominant hand to have less function (degree of freedoms, payloads etc.) than assistive devices for dominance hand.

Magic is a performance unique to humans that makes use of hand's skills to its maximum extent. It needs enormous efforts to acquire the skills of magic for a skillful man. In this study, a robot hand that can handle a small object in the palm and perform coin magic making full use of its palm and fingers. It is said that the coin magic is one of the most difficult kinds of magic. Therefore, we expect that a robot that can do coin magic may be able to do any magic successfully. In this paper, a mechanism of the robot hand is studied and the control methods of handling coins for the magic is discussed. The robot is assumed to use a Japanese 500 yen coin during the performance and it is assumed that the robot controls the hand by using only the information from the palm sensors. It is the problem how to design the skilful hand, how to construct a control algorithm, and what sensors should be used to sense the state variables of the coin.
