  • In this paper, we propose a method for simplifying the modeling of 'walk' for various instances of quadruped and easily extending the model of 'walk' for the instance of new subordinate class which is not defined in the original class hierarchy by using the sophisticatedly modeled 'walk' of quadruped. To achieve this method, we apply the analyzed pattern of walk and classification according to the structural similarity of quadruped studied in the previous researches to the class hierarchy and propose a method for inheriting the actions of super class. This paper model the 'walk' of quadruped by concertizing the characteristics of quadruped and defining the necessary factors and appropriate domains in terms of parameters of 'walk' and apply the model to the horse and cow, typical instances of quadruped.

  • Most of the existing multiped walking robots are biomimetic, i.e. they are designed to have the shapes of living things such as animals or insects. Even though those robots are familiar to us, they have some drawbacks in the view point of walking efficiency such as stability and walking speed. In this paper, we introduce a quadruped walking robot that can perform fast and stable walking by virtue of its distinctive leg positions. The proposed quadruped robot has a foreleg, a hindleg, a left leg, and a right leg. In the conventional robots, dynamic walking is needed to increase walking speed. Dynamic walking is difficult to be accomplished and is apt to be unstable. The proposed robot can move its legs in a manner that its center of gravity is always laid in the supporting polygon, so it can perform fast and stable walking without dynamic walking.

  • Research on high-performance walking robots is being actively conducted, and quadruped walking robots are receiving a lot of attention due to their excellent mobility and adaptability on uneven terrain, but they are difficult to introduce and utilize due to high cost. In this paper, to increase utilization by applying intelligent functions to a low-cost quadruped robot, we present a method of improving uneven terrain overcoming ability by mounting IMU and reinforcement learning on embedded board and automatically detecting objects using camera and deep learning. The robot consists of the legs of a quadruped mammal, and each leg has three degrees of freedom. We train complex terrain in simulation environments with designed 3D model and apply it to real robot. Through the application of this research method, it was confirmed that there was no significant difference in walking ability between flat and non-flat terrain, and the behavior of performing person detection in real time under limited experimental conditions was confirmed.

  • Commonly eaten fish, meat and other protein-containing foods show some level of mutagenic activity following normal cooking such as broiling, frying, grilling, roasting etc. The main food mutagens found in cooked products are“heterocyclic aromatic amines”. Several of them have been shown to be carcinogenic in rodent and suggested to be relevant for human cancer etiology. This review summarizes the chemistry, formation, occurrence and toxicity of food-borne heterocyclic aromatic amines. Factors that influence the formation of them are also discussed with special emphasis on dietary factors. From a health safety point of view, it is desirable to estimate the intake of heterocyclic amines via foods, and reduce or prevent the formation of food mutagens.
