In recent years, introduction of autonomous mobile robots which support humans in environments close to our life is expected. Examples are shopping support robots and porter robots carrying the luggage while accompanying the person. To utilize these robots, real time motion control of the robots is important. In this paper, we propose a mobile robot system which performs the actions by recogniz...

ÐThis paper describes a framework for developing mobile software robots by using the PLANET mobile object system, which is characterized by language-neutral layered architecture, the native code execution of mobile objects, and asynchronous object passing. We propose an approach to implementing mobile Web search robots that takes full advantage of these characteristics, and we base our discussi...

A decentralised large-scale network of mobile robots for multitarget tracking is addressed in this paper. The decentralised control is originally built up by behavioural control but upgraded with connectivity maintenance and hierarchical connectivity removal. The multi-target tracking algorithm guarantees that the mobile robots can reach the targets at the very high success rate while at least ...

Introductory AI courses present students with difcult theoretical issues related to the intelligence and behavior of agents operating in the world. We believe that mobile robot projects, when integrated with readings and discussions, help students bridge the gap between abstract AI theory and implementation. In this article we describe an introductory AI class designed around readings, discussi...

In this paper, we propose a method of an object manipulation by multiple mobile robots using sticks as tools. In the conventional cooperative work by multiple mobile robots, manipulation technique based on force-control has been proposed. However, mobile robots are moving by position-control, and motion errors can easily arise. Then, we build the manipulation technique, which is suitable for mo...
