A component is a reusable and replaceable software module accessed through its interface. Component‐based development is expected to shorten the development period, reduce maintenance costs, and improve program reusability and the interoperability of components. This paper proposes a new robot software component platform in order to support the entire process of robot software development. It consists of specifications of a component model, component authoring tool, component composer, and component execution engine. To show its feasibility, this paper presents the analysis results of the component's communication overhead, a comparison with other robotic software platforms, and applications in commercial robots.

An approach to identifying a caller or callers by a perception field and introduce the Cognitive Robotic Engine service robot is presented for a natural interaction with people (CRE) that takes the best out of the human approach to in a home/office environment. The problem addressed reliable and dependable perception. specifically in this paper is how to successfully identify a caller A. Background in a cluttered environment with large uncertainties involved in Dautenhahn [10] has listed different social relationships the sensed audio-visual cues. The proposed approach is based on a proposition that the dependability of perceptual recognition between robots and humans based on animal-human may come unlikely from "the effort to make individual sensing relationship. In recent years there has been a great deal of perfect," but likely from "the effort to self-generate perceptual interest to develop algorithms and systems for human-robot behaviors of integrating individual sensing that lead to mission interface, for instance see [2][8]. Most of these researches accomplishment, no matter how imperfect and uncertain focused on the problem of proper response to the human individual sensing may be." We implement the above while the reliable and dependable recognition and perception proposition in terms of a novel robotic architecture, referred to remains of a critical issue. On the other hand, the robot's here as "Cognitive Robotic Engine (CRE)." CRE implemented hardware dependability has been under investigation for a for the case of a robot identifying a caller in a crowed and noisy ime, i.e. exet valid and safe commands, from the envlronmeit,ncungIS experimental results, are shown. lon t ecuin environment, including its experimental results, are shown. old industrial robots to the new mobile platforms.

Robot software components, which can be accessed through their interface, are reusable and replaceable software modules used in composing robotic services. Using robot software components in developing a robot, developers can expect shortening of developing times, reduction of maintenance cost and improvement of program reusability, because interoperability among components is guaranteed. We have developed a component framework assisting robot developers to make robot application with ease. The component framework consists of a specification of component model, a component authoring tool, a component composer, and a component container. In this paper, we will not only show the developed component framework, but also demonstrate its usability by applying to commercial robots.
