Robot From Power Chair Follows Wall

This time I wanted to continue to use the controller I already had and add sensors.  To test my ideas, I made a pretty simple wall follower type algorithm and that made it happen like this:

So now I can keep a robot on the straight and narrow using IR in close quarters.   I expect a sonar would also be nice, so I guess I will have to add a sonar ping'er and give that a try.

Next time, though, I'm really thinking about making something really practical for wheelchair owners.  Not that it isn't practical to manage a wheelchair through narrow passages, but that can come later.
