摘要: An adaptive vision based controller for controlling a robot arm comprises a camera, a segmenter for analyzing images from the camera, a tracker, sketcher and ranger responsive to information from the segmenter for creating a three dimensional segmented data list, a recognizer for receiving the data list and comparing data in the list against a database of plausible objects, and a planner interactive with the recognizer and responsive to task definitions for developing control outputs. The recognizer uses scenic information such as feature maps produced by the segmenter in conjunction with a knowledge base to construct a world model. The planner uses the world model and the task definitions to construct a plan in the form of a set of actions for accomplishing the defined task. By way of the control system, information about how the robot arm is actually performing a task can be compared with the desired task and the task can be updated if necessary. Thus the controller provides visual feed back control of the task performed by the robot arm.
