— In this paper, we propose an approach to the behavior acquisition required for humanoid robots to learn a cooperative transportation task. In case of object transportation with two humanoid robots, mutual position shifts may occur due to the body swinging of robots. Therefore, it is necessary to correct the position in a real-time manner. Many efforts are(More)
In this paper, we describe a field experiment of an autonomous mobile system to navigate users and to estimate the self-position indoors, where it is impossible to receive a GPS signal. Many users utilize positional information systems of GPS. However, because positional information computed using GPS signal is available only in the locations with satellite(More)
In this paper, we propose a wireless sensor network system called <i>ComPass System</i>, which uses low-power radio to provide services in everyday environments, such as indoor positioning services in public spaces. Although such environments present difficult hindrances such as dynamic changes of physical status, the ComPass System is designed to operate(More)
In this paper, we describe a cooperative transportation problem with two humanoid robots and introduce a machine learning approach to solving the problem. The difficulty of the task lies on the fact that each position shifts with the other's while they are moving. Therefore, it is necessary to correct the position in a real-time manner. However, it is(More)
Piperine (PP) is a pungent component in black pepper that possesses useful biological activities; however it is practically insoluble in water. The aim of the current study was to prepare a coground mixture (GM) of PP and β-cyclodextrin (βCD) (molar ratio of PP/βCD = 1/1) and subsequently evaluate the solubility of PP and physicochemical properties of the(More)
The aim of this study is to examine the physicochemical properties of the external preparation, the effect on the skin permeability and the human senses. Miconazole nitrate cream formulation (MCZ-A: bland name and MCZ-B, -C, -D: generics) to measure the physicochemical properties, was performed by the skin permeation test and human sensory test. The(More)
