I&#x27;m surprised that a chapter titled &quot;Intelligence and embodiment&quot; (ch.1) would not include even a reference to Rod Brooks (MIT Mobile Robot Lab).<p>Brooks&#x27; invention of &quot;subsumption architecture&quot; (augmented finite state machines) and layered control systems in which higher level behaviors suppress low-level behaviors has been demonstrated to lead to robust intelligent behavior without centralized control, internal mapping, and emergent behavior. In short, a biologically-inspired solution which had tremendous influence in the field. To my mind, such an omission is a bit like writing a book on computer graphics and not including a reference to Watt, Foley or vanDam. Not saying it&#x27;s wrong, just very surprising.
