1,, when adding or delete sensor and auxiliary function module, need the analysis-by-synthesis algorithm in the redesign main control module.This makes the existing robot system of renewal become of a high price.
2, service robot is mainly used to receives user's and carries out, and without the need for very strong capacity of will, but requires good real-time.Yet along with the continuous increase of robot sensor and auxiliary function module, the analysis-by-synthesis algorithm of main control module can become very complicated, will affect the real-time of service robot.
3, complicated main control module can be very high to processor requirement, and the hardware cost that this will improve service robot, affect the popularization of service robot.
The Brooks of MIT once proposed a kind of containment type level framework (subsumption) and overcame " perception → plan → action "
The shortcoming of (" Sense → Plan → Act ") framework.In containment type level framework (subsumption), robot control system is divided level by the Task-decomposing parallel processing, between level, use the simple mechanism (suppression and inhibition) that suppresses to be coordinated, there is no main control module.Use the robot of containment type level framework that Myrmix etc. is arranged, have very high real-time performance.
But there are two major defects in containment type level framework (subsumption):
1,, when system level increases, be difficult to design inhibition mechanism and decompose well parallel by task.
2, from circuit aspect control, so robot control system does not possess portability.
In recent years, company of many robots is (as Japanese Vstone Co., Ltd., Beijing Universal Pioneering Technology Co., Ltd. etc.) by the abstract interface that becomes the C/C++ language of the control of hardware view, this separates with robot hardware's platform for robot control system, realizes that the portability of robot system provides technical support.
