A hybrid control architecture using a reactive sequencing strategy for mobile robot navigation

摘要

Proposes a hybrid control architecture which combines the key features of the two well-known robot control architectures; hierarchical and behavioral-based. The overall control architecture consists of three layers, i.e. the high-level planner, the middle plan executor, and the lower level monitor and behavior-based controller. In the planned task, only one behavior module is chosen by the logical coordinator in the plan executor according to the way point bin. In the exceptional situation, the central controller in the plan executor issues an additional control command to reach the planned way point. Several simulations and experiments with an autonomous mobile robot show that the proposed architecture enables the robot controller to achieve the multiple sequential goals even in a dynamic and uncertain environment.
