We have proposed a fast learning method that enables a mobile robot to acquires autonomous behaviors from interaction between human and robot. In this research we develop a behavior learning method ICS (Interactive Classifier System) using interactive evolutionary computation considering an operator's teaching cost. As a result, a mobile robot is able to quickly learn rules by directly teaching from an operator. ICS is a novel evolutionary robotics approach using classifier system. In this paper, we investigate teacher's physical and mental load and proposed a teaching method based on timing of instruction using ICS.

A hardware object is a capsule of circuits loaded into reconfigurable devices. It is dynamically constructed while an application run. Its driver is temporarily mounted on a real driver for a hardware module. The circuits axe suitable to preprocessing and postprocessing of robot systems. A commercial C++ compiler becomes an integrated design environment only attaching hardware object components and hardware object libraries.
This paper describes the development and the application of an object tracking algorithm from a sequence of images. The algorithm is based on window-matching techniques using the sum of squared differences (SSD) as a ...

Recently, various learning methods are adapted for experimental robot. We can make movement of a robot by giving teaching signals to a robot. But it is heavy for operator to define how to give teaching signals generally because operator must guess and think of a task and environment and define a function to do that. Here I aim to create teaching signals automatically for each task and environment. In this paper, I suggest a simple rule which is independent of information about any task and environment to create teaching signals for each task and environment. This rule is that a situation which is often happened is good situation. In this paper, I adopt reinforcement learning as learning method and a small-sized humanoid robot as application. I will show creating a reward by adapting a rule and show that a robot can learn and make movement.

This paper presents a global localization method based on map matching. A local map is built by successive splitting and merging scan points. A global map is built by merging all local maps. Local and global map are represented with line segments that are sorted counterclockwise. Complete line segments are selected to match between two maps. Matching is based on relative position relation of complete line segment. Localization algorithm based on ordinal map and based on relative position relation improves matching efficiency and lowers computational cost. All these techniques have been implemented on our mobile robot ATRVII equipped with 2D laser range scanner SICK.
A long-standing question in cognitive sciences and machine learning is how a system can develop high-level concepts and categories which are useful for motor and cognitive control. I propose an architecture which lear...

Physics-based animations executing on 3D game engines enabled with physics middleware libraries and coprocessors can be used to explore the suitability of potential robot behaviors in working environments and robot configurations that are ill-defined or difficult and time-consuming to model with traditional quantitative tools. We use an inexpensive game development engine and PC hardware to develop physics-based animations of potential biomimetic subterranean robot burrowing behaviors. Qualitative assessment of energy efficiency, burrowing time, and digging capabilities of several biomimetic robot designs are validated with data from physical prototypes operated in a range of soil types and models of soil using colored particles. Results suggest this methodology is applicable to rapid screening of potential robot designs intended to operate in a variety of domains.
