Make a wall avoiding Robot

Jan 01, 2013 Posted by Abhi Raj

Objective: To create from scratch a working robot that is able to avoid walls and obstacles.

Ever wanted to make a robot that could actually do something, but never had the time or knowledge to do it? Fear no more, this instructable is just for you! I will show you step by step how to make all the necessary parts, and programs to get your very own robot up and running. I was first inspired to build a robot when I was ten, and saw Lost in Space, with that famous B-9 robot, I wanted one! Well six years later I finally built a working robot.
