ATOMI II - Framework for Easy Building of Object-oriented Embedded Systems

4th IEEE International Symposium on Electronic Design, Test and Applications (Delta 2008)

2008

Arbitration methods are needed to prevent conflicts when several processing units share a common resource. Despite of there being a plethora of different arbitration methods available, there is not an optimal solution for every case. Our case requires a distributed, modular, simple, fast, freely scalable, and inexpensive arbitration method. Emerged from our special need, we have developed a simple daisy chain type of arbitration that is modularly expandable and implements a geographical priority scheme with a possibility for dynamic priority. This arbitration can be implemented with two inexpensive 74-series logic gates or programmable logic. It can be used with systems that require arbitrary modular scalability, few IO-lines and low cost.

Low Cost Arbitration Method for Arbitrarily Scalable Multiprocessor Systems

4th IEEE International Symposium on Electronic Design, Test and Applications (Delta 2008)

2008

“…The telepresence robot is implemented with the second generation of embedded objects. The telepresence robot test case aims to validate some EOC-related issues: the suitability of the EOC for relatively complex systems, the functionality of the Atomi II -framework [3], object-oriented design, and incremental device development.…”

A telepresence robot system realized by embedded object concept

2006

SPIE Proceedings

This paper presents the Embedded Object Concept (EOC) and a telepresence robot system which is a test case for the EOC. The EOC utilizes common object-oriented methods used in software by applying them to combined Lego-like software-hardware entities. These entities represent objects in object-oriented design methods, and they are the building blocks of embedded systems. The goal of the EOC is to make the designing embedded systems faster and easier. This concept enables people without comprehensive knowledge in electronics design to create new embedded systems, and for experts it shortens the design time of new embedded systems. We present the current status of a telepresence robot created with second-generation Atomi-objects, which is the name for our implementation of the embedded objects. The telepresence robot is a relatively complex test case for the EOC. The robot has been constructed using incremental device development, which is made possible by the architecture of the EOC. The robot contains video and audio exchange capability and a controlling system for driving with two wheels. The robot is built in two versions, the first consisting of a PC device and Atomi-objects, and the second consisting of only Atomi-objects. The robot is currently incomplete, but most of it has been successfully tested.

“…This paper presents the latest implementation of the EOC and the telepresence robot test case. The latest implementation of the EOC is compiled as a set of specifications, which we refer to as the Atomi II framework [3]. The Atomi II framework consists of a set of techniques and physical measures for creating mutually compatible embedded objects.…”

The robot contains video and audio exchange capability and a controlling system for driving with two wheels. The robot consists of Atomi-objects, demonstrating the suitability of the EOC for prototyping and easy modifications, and proving the capabilities of the EOC by realizing a function that normally requires a computer. The computer counterpart is a regular PC with audio and video capabilities running with a robot control application. The robot is functional and successfully tested.
