What is Subsumption Architecture?

Subsumption architecture is the mechanism by which complex intellectual behaviors are divided into a number of simple behavioral modules, gives hierarchical structures to each module, and higher-level behaviors control lower-level behaviors in it.

Tell me more!

・Higher Controls Lower

The organism intelligence is estimated to have its own hierarchical structure. For example, organisms “go straight to the smell of food." However, it is necessary to “bypass the hole if there is it.” How do we implement such functions in AI? At this time, the "Subsumption Architecture" realizes the idea that "go straight" behavior at the bottom should be suppressed while "bypass" behavior is prioritized, as well as the higher is authorized to control the lower. (Subsumption Architecture – iCardbook | https://society-zero.com/icard/235382 )

・The History of Robot Development

Subsumption Architecture emerged in the history of robot development. Before this, robot read information from sensor, calculated the environment surrounding it, determined the best behavior, and ran motor. This method had a disadvantage: movement and reaction of robot were slow, while worked correctly.
The advantage of Subsumption Architecture is a quick response.

・Roomba

The cleaning robot, Roomba is also equipped with Subsumption Architecture. Thanks to this, Roomba shows "avoid when hitting" behavior quickly.

In contrast, former robot before Subsumption Architecture were made “not to hit.” First, it checked the surrounding environment of a room, and move after grasping obstacles in advance. To realize this, advanced systems, which looked around the entire space by sensor, created a virtual map, considered obstacles, and controlled its body, were aspired and under development with a huge amount of operation.

The idea of Subsumption Architecture is also responsible for the imitation of organism intelligence, to construct AI of game characters. Doing so, arguments of “Matter and Memory” by a philosopher, Bergson, and the idea of internal time of organism, should be referred.
