Subsumption architecture uses a layered design with multiple processors.

• A. True
• B. False
• C. Not sure
• D. Both

Answer: (A)

Subsumption architecture builds robot control from layers of behavior, each layer handling a different level of control and capable of running its own processing path. Lower layers take care of fast, reflexive motor actions, while higher layers implement more complex goals and can override or inhibit the actions of lower layers when necessary. Because these layers are designed to operate in parallel, they’re typically implemented as separate processors or processing streams. This parallel, modular setup lets a robot respond quickly and reliably to changes in its environment, with higher-level goals guiding behavior without a single centralized planner. So the statement is true, reflecting both the layered structure and the tendency toward multiple processing paths that enable concurrent operation.
