Subsumption architecture is a reactive robotic architecture heavily associated with behavior-based robotics which was very popular in the 1980s and 90s. The term was introduced by Rodney Brooks and colleagues in 1986. [1] [2] [3] Subsumption has been widely influential in autonomous robotics and elsewhere in real-time AI.
A behavior tree is graphically represented as a directed tree in which the nodes are classified as root, control flow nodes, or execution nodes (tasks). For each pair of connected nodes the outgoing node is called parent and the incoming node is called child.
Constituents in a node from James Albus's Reference Model Architecture. James Albus, while at NIST, developed a theory for intelligent system design named the Reference Model Architecture (RMA), [6] which is a hierarchical control system inspired by RCS. Albus defines each node to contain these components.

The main issue of MIBE architecture is the difficulty of modeling the optimal boundaries of the state-space by shaping the motivational structure (i.e.: tuning the drive-generation functions or their learning algorithms) so that the autonomous agent performs the best behavior for each robot+environment state (however the same difficulty also ...
Behavior-based robotics (BBR) or behavioral robotics is an approach in robotics that focuses on robots that are able to exhibit complex-appearing behaviors despite little internal variable state to model its immediate environment, mostly gradually correcting its actions via sensory-motor links.
However, upon Rodney Brooks' introduction of subsumption architecture, which enabled robots to perform "intelligent" behaviour without using symbolic knowledge or explicit reasoning, increasingly more researchers have viewed intelligent behaviour as an emergent property that arises from an agent's interaction with the environment, including ...
The following outline is provided as an overview of and topical guide to robotics: . Robotics is a branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.
