This book is a collection of the "best" / most cited Brooks papers. Basically it covers what is considered the core of papers that got behaviour based robotics rolling. Almost all papers have appeared as journal papers earlier and this is merely a convenient collection of these.

For anyone working on mobile robotics these papers are a must. I.e. everyone ought to know these papers, both because they are thought provoking and widely referenced. For anyone with access to a library it might be an overkill to pay for this book. Go to the library and read the papers.

The real disappointment here is the lack of a historical perspective. These papers are all 5-15 years old. They strongly influenced the robotics world when they were published. The examples are interesting, but for REAL everyday robot systems the world is more complex than indicated by Brooks. It would have been interesting to see a final chapter that discussed lessons and limitations of the approach when seen in a historical perspective. Brooks is now building a humanoid system (Cog) and one wonders how many of the behaviour based ideas made it into Cog? Probably not as many as this book might indicate.

If you have a library, use you money on an upto date book! If not, you ought to acquire it for a view of the history.
