Area of Science:

  • Robotics
  • Computational Neuroscience
  • Artificial Intelligence

Background:

  • Attentional processing is crucial for robots to interact with dynamic environments.
  • Existing robotic systems often lack sophisticated mechanisms for selective stimulus processing.

Purpose of the Study:

  • To introduce and evaluate a novel neural network architecture, the pointer map, for implementing attentional processing in robots.
  • To demonstrate the utility of pointer maps in enabling a robot to maneuver in relation to attended objects.

Main Methods:

  • Developed a controller using two pointer maps and a motor map.
  • The first pointer map processed one-dimensional distance data from infrared sensors to identify obstacle direction.
  • The second pointer map processed two-dimensional image data from a CCD camera for obstacle detection and direction.
