How to recognise dark places?
October 15, 2008
We're trying to create a robot that can "see" dark places and drive to it for our final project for school... One of the things it must be able to do is of course finding the dark places. Since we have nearly no experience with building robots we hope there are some people in here that could help us with some (easy?) questions.
One of our questions is how to recognise dark places. Our first idea was to use LDRs for it. But what do you guys think is the best to do, place 1 LDR on each side of the robot, or use a servo with LDRs mounted on it? Or perhaps there is another way to recognise dark places? Please mention.
We are thinking about buying a PICAXE 28X to make it all work because it looks like it's quite easy to program, it's cheap and that we can find a lot of feedback on the www.
Another thing the robot must be able to is to avoid objects. After looking around we think the best way is to use a Sharp GP2D120 IR Sensor.
Please let us know what you think about our ideas or if there are better ways to do it.
Thanks in advance,
