The picture on the right shows two mobile robots (black dots) searching for an intruder (target) in a polygonal environment. The three pictures on the right illustrate sensorless part orientation.

  • Topics
    - Principles of criticality-based planning
    - Application to finding an evasive target in a polygonal environment
    - Planning in a belief/information space
    - Application to automatic part orientation with a two-jaw gripper
    - Taking advantages of task mechanics
