A new design method of control module based on the concept of Agent is proposed, so that the intelligent wheelchair bed can always be ready for accepting control instruction from other objects around it, while itself is under independently operation. The command sequence for the motion choices that conform to the overall demand can be given by the perception fusion of the sensor groups information, the state machine information of the wheelchair bed, and the external collaborative information. After completing complex cross judgment and consultation, the coordinated operation of the external commands and the local autonomous control are collaborative executed, via the timely synthesis of the sensors group information, the external remote command information, and the accumulation of learning library information. To use the intelligent wheelchair bed, the control module based on the concept of Agent, can easily satisfy both independent intention and service obtained from other objects around it. At the same time, it is also very convenient for monitoring personnel to solve some special problems by remote control instruction. The test shows that the operation efficiency of the intelligent wheelchair bed is improved significantly.
