A robot 'architecture' primarily refers to the software and hardware
framework for controlling the robot. A VME board running C code to
turn motors doesn't really constitute an architecture by itself. The
development of code modules and the communication between them begins
to define the architecture.
Robotic systems are complex and tend to be difficult to develop. They
integrate multiple sensors with effectors, have many degrees of
freedom and must reconcile hard real-time systems with systems which
cannot meet real-time deadlines [Jones93]. System developers have
typically relied upon robotic architectures to guide the construction
of robotic devices and for providing computational services (e.g.,
communications, processing, etc.) to subsystems and components. These
architectures, however, have tended thus far to be task and domain
specific and have lacked suitability to a broad range of applications.
For example, an architecture well suited for direct teleoperation
tends not to be amenable for supervisory control or for autonomous
use.
One recent trend in robotic architectures has been a focus on
behavior-based or reactive systems. Behavior based refers to the fact
that these systems exhibit various behaviors, some of which are
emergent [Man92]. These systems are characterized by tight coupling
between sensors and actuators, minimal computation, and a
task-achieving "behavior" problem decomposition.
The other leading architectural trend is typified by a mixture of
asynchronous and synchronous control and data flow. Asychronous
processes are characterized as loosely coupled and event-driven
without strict execution deadlines. Synchronous processes, in
contrast, are tightly coupled, utilize a common clock and demand hard
real-time execution.
