چکیده

Mohammed Abdel Ghani Dept. ofEE, S. Illinois University, Carbondale, IL A circuit for fast, compact and low-power focal-plane motion centroid localization is presented. This chip, which uses mixed signal CMOS components to implement photodetection, edge detection, ON-set detection and centroid localization, models the retina and superior colliculus. The centroid localization circuit uses time-windowed asynchronously triggered row and column address events and two linear resistive grids to provide the analog coordinates of the motion centroid. This VLSI chip is used to realize fast lightweight autonavigating vehicles. The obstacle avoiding line-following algorithm is discussed.

Effective Mechatronic Models and Methods for Implementation an Autonomous Soccer Robot

  Omni directional mobile robots have been popularly employed in several applications especially in soccer player robots considered in Robocup competitions. However, Omni directional navigation system, Omni-vision system and solenoid kicking mechanism in such mobile robots have not ever been combined. This situation brings the idea of a robot with no head direction into existence, a comprehensi...

Real-Time Autonomous Robot Navigation Using VLSI Neural Networks

We describe a real time robot navigation system based on three VLSI neural network modules. These are a resistive grid for path planning, a nearest-neighbour classifier for localization using range data from a timeof-flight infra-red sensor and a sensory-motor associative network for dynamic obstacle avoidance .

Robot Motion Vision Part II: Implementation

The idea of Fixation introduced a direct method for general recovery of shape and motion from images without using either feature correspondence or optical flow [1,2]. There are some parameters which have important effects on the performance of fixation method. However, the theory of fixation does not say anything about the autonomous and correct choice of those parameters. This paper presents ...

Autonomous Navigation for Miniature Indoor Airships

In recent years, embedded systems have become popular, and, for example, consumer electronics, transportation, and robotics are hard to imagine without them. As mobile devices with embedded systems are often supposed to act intelligently, they are usually equipped with sensors and actuators for interaction with humans or for autonomous operation. However, cost pressure and miniaturization impos...
