        abstract = {The aim of the research is to present an algorithm of obstacle distance estimation and navigation of robot. Obstacle detecting robot is an aid for visually challenged people. The robot is equipped with camera, line laser and microcontroller to navigate and avoid an obstacle.  The line laser is projected horizontally on the objects in the path. The presence of any object leads to a distortion in the line laser. The camera is used to capture this distortion to check pathway condition. The red line laser projection is detected by image thresholding of the Red frame of the captured image. A simple algorithm based on pixel count is implemented to find the distance between the distorted horizontal laser projections. The distance between the distorted laser projections is used to calculate the distance of the object using other constant parameters and acknowledge the position with respect to the camera frame. The data from the images is fed to microcontroller using Bluetooth module which further guides the motion of the bot.},
