1. Preface<br />
Embedded Intelligent System Lab is a research laboratory in <strong>the</strong> Department of Electrical Engineering.<br />
The members consisting of mainly graduate students in electrical engineering, computer science <strong>and</strong><br />
engineering, optic-mechatronic engineering <strong>and</strong> undergraduates of electrical engineering belong to<br />
this lab <strong>and</strong> carry out research projects. Moreover, this lab works in cooperation with two contributing<br />
laboratories, High Speed Networking <strong>and</strong> 3D Vision in <strong>the</strong> Department <strong>and</strong> <strong>the</strong> total number of <strong>the</strong><br />
staff <strong>and</strong> students are more than 30.<br />
In this article, Cooperative Autonomous Agents Project, Museum Tour Guide, <strong>and</strong> Digital Home<br />
Center among <strong>the</strong> research <strong>the</strong>mes of EIS Lab are described.<br />
2. Cooperative Autonomous Agents with Reinforcement Learning<br />
Multiple agents learn how to cooperate with each o<strong>the</strong>r to achieve a good which needs more than one<br />
agent to perform. The <strong>the</strong>ory developed has been applied to robotics <strong>and</strong> networking congestion<br />
control.<br />
Cooperative robots<br />
Two robots connecting with a straight bar learn how to take action independently to achieve <strong>the</strong> goal<br />
where <strong>the</strong> robots is cooperating with each o<strong>the</strong>r to pass through a gate.<br />
Congestion control<br />
Cooperative agents learn networking environmental dynamics empirically without prior information<br />
to increase <strong>the</strong> utilization of available links’ capacity <strong>and</strong> decrease <strong>the</strong> ratio of packet loss.<br />

3. Museum Tour Guide Project<br />
The objective of this project is to develop a mobile device for museum touring by which <strong>the</strong> tourists<br />
can plan <strong>the</strong>ir own visit path around exhibitions. Therefore, manpower <strong>and</strong> related resources of tour<br />
guides can be saved. Besides, <strong>the</strong> tourists can get real-time <strong>and</strong> detailed information for <strong>the</strong> works <strong>the</strong>y<br />
are watching or interested in. The device is designed based on <strong>the</strong> following <strong>the</strong> technologies in<br />
networking <strong>and</strong> embedded systems.<br />
Wireless connections<br />
The mobile device has been equipped with a passive Radio Frequency Identifier (RFID) such that a<br />
visitor can retrieve <strong>the</strong> information of a work via wireless LAN by its index received by <strong>the</strong> RFID.<br />
Recently, a new version with an active RFID is being developed at <strong>the</strong> EIS lab. The h<strong>and</strong>-set device<br />
can, in addition to providing <strong>the</strong> information of <strong>the</strong> works to a visitor approaching his/her interests,<br />
pinpoint <strong>the</strong> visitor’s location <strong>and</strong> provide <strong>the</strong> information about <strong>the</strong> surroundings information<br />
actively.<br />
Open sources<br />
The development is under <strong>the</strong> open source platform <strong>and</strong> utility, such as Embedded Linux for <strong>the</strong><br />
computing power, Qt Embedded for GUI, YAFFS for Flash <strong>file</strong> systems, NFS <strong>and</strong> networking <strong>file</strong><br />
system Coda for connections between <strong>the</strong> stations.<br />
4. Digital Home Center Project<br />
This project aims at intelligent appliances integrating wireless (802.11 WLAN , Bluetooth, RFID) <strong>and</strong><br />
wired (RS-232, RS-485, Power Line Controller) networking technologies to realize an intelligent<br />
networking home system illustrated in <strong>the</strong> following figure.
Mobile control device<br />
The mobile device functions as a SIP Phone, data storage, IR remote controller, <strong>and</strong> video/audio<br />
player. In this modern age, <strong>the</strong> objective of this project is to serve human being for a better life.<br />
5. Conclusion<br />
Wide range of research <strong>and</strong> development on applications of real-time embedded systems, cooperative<br />
agents system, intelligent chip design, etc, based on machine learning <strong>the</strong>ory <strong>and</strong> SOC technology are<br />
carried out in this lab. Please refer to web site of <strong>the</strong> lab for fur<strong>the</strong>r information. URL:<br />
