Hi everyone, this is the improved version of my previous Differential Drive Robot. I didnít think about any name yet; but will figure out one soon. Anyway, this improved prototype has an IR Rangefinder attached to it which can detect distance of any object in front of it within a range of 10cm to 80cm. And an extra servo is added to this new version to rotate the sensor left or right. Letís take a closer look at the new prototype.
Whenever the robot faces an obstacle in front of it, it looks left and right, and thinks about which side has enough space to go for. Then it turns to that side and moves forward. Check out the following video to see how the robot moves.
