| Summary: | Bio-Mimetic Vision System (BMVS) for Autonomous
Mobile Robot Navigation encompasses three major fields, namely
robotics, navigation and obstacle avoidance. Bio-mimetic vision is
based on stereo vision. Summation of Absolute Difference (SAD)
is applied on the images from the two cameras and disparity map
is generated which is then used to navigate and avoid obstacles.
Camera calibration and SAD is applied on Matlab software.
AT89C52 microcontroller, along with Matlab, is used to efficiently
control the DC motors mounted on the robot frame. It is observed
from experimental results that the developed system effectively
distinguishes objects at different distances and avoids them when
the path is blocked.
