To operate in dynamic environments robots must be able to adapt their behaviour to meet the challenges that these pose while being constrained by their physical and computational limitation. In this paper we continue our study into using biologically inspired epigenetic adaptation through hormone modulation as a way to accommodate the needed flexibility in robots’ behaviour, focusing on problem...

in this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. to this end, the dynamics model of the considered wheeled mobile robot is derived using lagrange equations of motion. then, using adams multi-body simulation software, the obtained dynamics of the wheeled system in matlab software is verified. after that, ...

Theoretically the birth of the humanoid robot arises from the study of human characteristics of movement. However, following the human model does not mean copying it. It is still a big challenge to develop an advanced humanoid robot. Most researchers have shown an interest in developing an ideal theory to keep the balance in various grounds while walking since it is so important for the surviva...

According to the behaviour-based philosophy, the structure of an agent’s internal representations of the environment should not be explicitly imposed by the designer; they should be grounded in its sensor-action space. This paper presents a scheme in which the agent’s action selection mechanism gives rise to an integrated spatial and topological navigation and mapping capability. The navigation...

This paper presents an experimental study to validate a dynamic model of a six-axis industrial robot as part of an assembly system and to analyze its power consumption as well as its dynamic behavior. Furthermore, the effect of robot operating parameters (i.e., payload and speed) on the power consumption and the dynamic behavior are analyzed. The investigation shows that the comparative study b...

This paper describes a novel action selection method for multiple mobile robots box-pushing in a dynamic environment. The robots are designed to need no explicit communication, and be adaptive to a dynamic environments by changing modules of behaviors. Though it is a significant problem to deal with adaptive action selection for multiple mobile-robots in a dynamic environment, few studies have ...

We propose a Case-Based Reasoning approach for action selection in the robot soccer domain presented in the 8th European Conference on Case-Based Reasoning (2006). Based on the current state of a game, the robots retrieve the most similar past situation and then the team reproduces the sequence of actions performed in that occasion. In this domain we have to deal with all the difficulties that ...

Visual attention is one of the most important issues for a vision guided mobile robot not simply because visual information bring a huge amount of data but also because the visual field is limited, therefore gaze control is necessary. This paper proposes a method of sensor space segmentation for visual attention control that enables mobile robots to realize efficient observation. The efficiency...

A robot that is to assist humans in everyday activities should not only be efficient, but also choose actions that are understandable for a person. One characteristic of human task achievement is to recognize and exploit opportunities as they appear in dynamically changing environments. In this paper we explore opportunistic behavior for robots in the context of pick and place tasks with human ...

Due to the complexity and sophistication of the skills needed in real world tasks, the development of autonomous robot controllers requires an ever increasing application of learning techniques. To date, however, learning steps are mainly executed in isolation and only the learned code pieces become part of the controller. This approach has several drawbacks: the learning steps themselves are u...
