The interest in robotics has been steadily increasing during the last decades. This
concern has directly impacted the development of the novel theoretical research areas
and products. Some of the fundamental issues that have emerged in serial and
especially parallel robotics manipulators are kinematics & dynamics modeling,
optimization, control algorithms and design strategies. In this new book, we have
highlighted the latest topics about the serial and parallel robotic manipulators in the
sections of kinematics & dynamics, control and optimization.
Robotics is the applied science of motion control for multi-axis manipulators and is a large
subset of the field of "mechatronics" (Mechanical, Electronic and Software engineering for
product or systems development, particularly for motion control applications). Mechatronics
is a more general term that includes robotic arms, positioning systems, sensors and machines
that are controlled by electronics and/or software, such as automated machinery, mobile robots
and even your computer controlled washing machine and DVD movie player....
This book grew of a third year optional course taught to electrical engineering students at South Bank Polytechnic.A parallel course on robot dynamics and control was taught by a colleague.For completeness,I have added here my own treatment of robots is,however,a very large subject area,which really reqires a book of its own.Many such texts already
In recent years, parallel kinematics mechanisms have attracted a lot of attention from the
academic and industrial communities due to potential applications not only as robot manipulators
but also as machine tools. Generally, the criteria used to compare the performance
of traditional serial robots and parallel robots are the workspace, the ratio between the
payload and the robot mass, accuracy, and dynamic behaviour.
The time required to reach other planets makes planetary surface exploration
missions prime targets for automation. Sending rovers to other planets either
instead of or together with people can also significantly reduce the danger and
cost involved. Teams of rovers are both more fault tolerant (through redundancy)
and more efficient (through parallelism) than single rovers if the rovers
are coordinated well

This book is intended for both mechanical and electronics engineers (researchers and graduate students) who wish to get some training in smart electronics devices embedded in mechanical systems. The book is partly a textbook and partly a monograph. It is a textbook as it provides a focused interdisciplinary experience for undergraduates that encompass important elements from traditional courses as well as contemporary developments in Mechtronics.
The nonholonomic nature of the car-like robot is related to the assump-
tion that the robot wheels roll without slipping. This implies the presence of
a nonintegrable set of rst-order dierential constraints on the conguration
variables. While these nonholonomic constraints reduce the instantaneous mo-
tions that the robot can perform, they still allow global controllability in the
conguration space. This unique feature leads to some challenging problems
in the synthesis of feedback controllers, which parallel the new research issues
arising in nonholonomic motion planning.
