Unobot 1–My First Bot


My first obstacle avoiding bot based on the tutorial by Community of robots.

This is my first one and helped me learn a bit about sensors, feedback and servo operations. One difference in mine is the use of IR proximity sensor which I had lying around instead of the Sharp distance sensor.

This one does not measure distance and just detects the obstruction. That is why if it has a obstruction on both left and right it turns right. Idealy it should turn towards the farther one.

This one has been made from simple L293D based driver on a breadboard and DC motors on a half chassis of a line follower bot Smile

The code is the exact copy paste from the tutorial just to see if this thing works and it did, you can see in the vdo below. Would be making some changes to the structure and the software and post soon.
