The problem of automatically generating the possible 3-D sensor locations for observing a scene is defined, and an approach to its solution is presented. The approach taken assumes that the sensor characteristics are well understood and that objects expected in the scene are known and modeled. Then, given a set of constraints, a set of actions is specified directing a robot arm to position itself in such a manner that an attached 3-D sensor located in the robot gripper yields the maximum information content with minimum effort with respect to the constraints. Techniques that yield solutions for placement of a triangulation-type 3-D laser range finder are presented.< >

A structure for sensory information organization and robot task planning is introduced, and HMP, a hierarchical multiprocessor computer architecture, is developed to support the real-time execution of the defined information structure. Queuing network analysis indicates that this hierarchical multiprocessor computer architecture, at least for the sets of loads defined, performs better than currently proposed systems based on single buses. All classes of data, except for large video data that have longer interarrival times, are transferred within 10 milliseconds, and most data are transferred at rates that are very close to their theoretical maximum speed. The gates, used for partitioning the buses, have also been successful; data transfers among processors inside the segment isolated by the gate have been speeded up while the transfer between clusters has either stayed the same or has been reduced slightly, compared to a system without gates.< >

A robotic system that can visually track and intercept an arbitrary object which is traveling at an unknown velocity on a conveyor has been presented. A fiber-optic eye-in-hand vision system developed at NCSU is used as an integral part of the entire tracking system. The eye-in-hand system is used to characterize the object trajectory in real time, using a modified optical flow approach. A control strategy has been developed which utilizes the kinematic data that are extracted by the tracking algorithm to intercept the moving object. An overall system configuration and its basic principles are described. The demonstration of the initial results is presented.< >
