ABSTRACT This paper is presented a development of a mathematical model of mobile humanoid robot. It is following deductive principle, i.e. to start from a completely general model applicable to a set of tasks. Such a model is further adjusted according to need certain specific situations. The robot is wheeled humanoid robot as a structure composed by upper human-like body and cart mobile platform. The cart construction is supported by 4-wheels configuration, electric drive on the rear vehicles, and is directed from the front wheels. A general simulation system is realized at movement in a horizontal (2D) plane and the robot is modeled as a 3-DOF system (three degrees of freedom). We have considers a known environment where fixed potentials were assigned to the goal and the obstacles. It moves successfully within different obstacle configurations (closely spaced obstacles), and it solves the problem with a local minimum occurrence. Researches made in the paper are new opportunities and directions for new researches. As expected, the robot can easily handle low speed cart movements, and intuitively problems appear with an increase in speed. We restricted the consideration to cart motions which are relevant to the humanoid robot working in human-centred environments. A mobile robot is usually intended to work in services; so in homes, department stores, restaurants, museums, hospitals etc. The working conditions of humanoid and semi-humanoid robots directly determine the requirements related to the ability of robots to maintain balance, stay stable, remain accurate and provide the qualities to perform controlling tasks in the given circumstances of functioning. KEYWORDS Keywords: Mobile robots, Guidance and control, Obstacle avoidance. Robustness, Robot Posture. 1 Introduction This paper attempts to developed dynamic mathematical model of antropomimetric robot (driven robot) to real motions, particularly in posture stabilization for different situation. In principle, modeling may follow an inductive approach or a deductive one. We apply deductive one, and we use the term flier. This situation is not uncommon in reality; However, such motions are still less common than those where the system is in the contact with the ground or some other supporting object in its environment. The concept of the flier approach, derived for humanoid robots, is then applied [3,4]. It originally dealt with a full humanoid (pelvis, torso, arms, legs, head). ECCEROBOT1 applies only a part of it to the upper- body robot of Fig. 1. In a past few years a new expression has been established –anthropomimetic [2]. Anthropomimetics refers to a new kind of robotics which copies the human body as faithfully as possible with the aim of achieving a level of performances (diversity of motions, maneuverability, etc.) comparable with that of a human. ECCEROBOT has joints driven by antagonistically coupled DC motors. The two joint motors, the agonist and antagonist, working
