Wireless RF Remote for Power Chair Twenty USD

The latest video on CwhatIcanDo.com.  This one is for people with power chairs who would like to be able to have wireless control over their wheelchairs.  This one can allow freedom to move your chair aside when you plop down in a favorite chair or visit with people at the table.  Just move the power chair aside under remote control.

This is about as simple as you can make a thing.  Once I established the presence of a 3 volt power source, I knew I could run the whole unit on 12 volts directly from the power chair.  (Remember in another project, we use an H-bridge to robotically control things?)

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.
