As virtual human of agriculture intelligent about operating environment and target of complexity and uncertainty, Virtual human operator is not an effective access to navigation knowledge to conduct its decision making .To solve these problems, the put use Congolog to action planning of virtual human. Virtual human found a high level of uncertainty from some of the legal procedure of formation of the implementation of the mandate of action sequences, replaced the virtual human from the initial state to the target state for the action sequences. So as to take virtual human encountered by the complexity and uncertainty. Finally, JAVA and Congolog take for virtual human of intelligent agriculture to picking fruit.
