Hi, want to know what is requirements to do application like this Enclosure Escape and Object Seeking there is a questions I hope to know

((1)) RoboEarth Recognition system use SIFT algorithm for object recognition so may use this ?!

((2)) How you query the robot to recognize object ?! do I have to build an interface for this ?!

((3)) Do I have to build an action plan or just do interrupt for event ?!

((4)) There is many nodes will run so how to give one node a priority over other to be executed in specific sequence ?!
