Structured vs. Unstructured Environment

结构化 / 非结构化环境Common

In a structured environment, objects and workflow are fixed and predictable; an unstructured one is cluttered and cannot be specified in advance.

This is a pair of terms describing how predictable a robot's working environment is. A structured environment is a place like a factory production line: the position, orientation, and timing of each workpiece are all designed in advance, so the robot can simply repeat a fixed program — this is where traditional industrial robots mostly work. An unstructured environment is a home, a store, or the outdoors: objects are placed however people like and get moved around, lighting and ground conditions vary widely, and people are moving through the space, so no fixed sequence of actions can be hard-coded in advance. One of the central problems embodied AI wants to solve is moving robots from structured into unstructured environments, which requires perception, generalization, and real-time decision-making rather than relying purely on taught, programmed motions. In between the two sits the “semi-structured” setting, such as a warehouse's shelving area.

ExampleOn an auto welding line, every car body stops at exactly the same position — a structured environment; the dishes and utensils on a home kitchen counter are arranged differently every day, with people walking around nearby — an unstructured environment.
