Typically Sharp IR sensors are used to get an analog reading for the distance to a wall and in turn use PID. So, in order to try and push the boundaries and/or be different than most I had an idea and I was wondering if someone more experienced could offer some insight into the feasibility of this idea.
So, I know that the QR sensors have a max readable range of about 1/2 inch so I thought about using the same idea but with much higher wattage IR sensor/detector pairs. I was looking at using the star styled 1W dissipation LEDs shown here. For the receiver I was looking at using the component here.
So, ultimately, my question is, if I have a four inch wide robot in a twelve inch wide “hallway” would my reflectance sensor be able to give a good variance in the reading from the receivers or would the walls be too far away?
A couple of other reasons I want to do this other than being different are:
[ul]*Sharp sensors are “slow”, the best rate is 16ms per reading and I want my robot to go at least 3 ft/s
*Sharp sensors are very focused and tend to be hard to detect objects like chair legs (my receivers have 80 degree visibility[/ul]
