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...

Research in Progress in Robotics at Stanford University

The Robotics Project (the ‘Hand-Eye Project’) evolved within the Stanford Artificial Intelligence Laboratory under the guidance of John McCarthy, Les Earnest, Jerry Feldman, and Tom Rinford. Major efforts have been undertaken to isolate and solve fundamental problems in computer vision, manipulation, and autonomous vehicles. Generalised cones were introduced for modelling the geometry of 3-dime...

Optical Navigation by the Method of Differences

The method of differences refers to a technique for image matching that uses the intensity gradient of the image to iteratively improve the match between the two images. Used in an iterative scheme combined with image smoothing, the method exhibits good accuracy and a wide convergence range. In this paper we show how the technique ran be used to directly solve for the parameters relating two ca...

A Q-learning Based Continuous Tuning of Fuzzy Wall Tracking

A simple easy to implement algorithm is proposed to address wall tracking task of an autonomous robot. The robot should navigate in unknown environments, find the nearest wall, and track it solely based on locally sensed data. The proposed method benefits from coupling fuzzy logic and Q-learning to meet requirements of autonomous navigations. Fuzzy if-then rules provide a reliable decision maki...

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 ...
