The 6th International Symposium on Distributed Autonomous Robotic
Systems (DARS 2002) was held in June 2002 in Fukuoka, Japan, a
decade after the first DARS symposium was convened. This book,
containing the proceedings of the symposium, provides broad
coverage of the technical issues in the current state of the art in
distributed autonomous systems composed of multiple robots, robotic
modules, or robotic agents. DARS 2002 dealt with new strategies for
realizing complex, modular, robust, and fault-tolerant robotic
systems, and this volume covers the technical areas of system
design, modeling, simulation, operation, sensing, planning, and
control. The papers that are included here were contributed by
leading researchers from Asia, Oceania, Europe, and the Americas,
and make up an invaluable resource for researchers and students in
the field of distributed autonomous robotic systems.

In ten sections this book describes the principles and technology
of Micro Mechanical Systems. Section one is a general introduction
to the historical background and the parallels to microelectronics,
reviewing the motivation for microsystems, and discussing
microphysics and design and the evolution from microcomponents to
microsystems. Section two covers the areas of photolithographic
microfabrication, basic concepts of planar processing, materials,
and processes. Section three looks at micromachining by machine
tools, its history, basic principles and preparation methods.
Section four discusses tribological aspects of microsystems.
Section five covers fabrication, performance and examples of
silicon microsensors. Section six looks at electric and magnetic
micro-actuators for micro-robots. Section seven covers energy
source and power supply methods. Section eight covers controlling
principles and methods of micro mechanical systems and section nine
gives examples of microsystems and micromachines. The final section
discusses the future problems and outlook of micro mechanical
systems.
Why are students not motivated? English levels, culture, class
sizes, previous education get the blame in university classes.
However, most students come into that first class wanting to learn,
and in most cases the teacher causes demotivation. The key to
sustaining or enhancing motivation lies within a classroom
atmosphere built on respect and trust with a syllabus guiding
students towards autonomy. Classes should avoid being only 'fun',
and need to foster learners who can continue their learning. This
monograph introduces and reports the outcomes of a guided-autonomy
syllabus compared to the syllabus of textbook fragmentation. The
guided-autonomy syllabus is a goal-oriented syllabus with the
teacher acting as a facilitator in an authentic learning
environment built on respect and trust gradually creating the
autonomous learner. It increases internal motivation starting
teacher-centered and gradually moving towards student-centeredness
through autonomy enhancing activities, primers in second language
acquisition, in an encouraging classroom atmosphere. A student,
after a guided-autonomy class said, "it was a great atmosphere,
meaningful, and not a waste of time."
