well said ..
wow DWV actually can see exactly what im trying to do. i did think of ure idea DWV and other ppl have siad the same thing. i'm attaching a picture here to say y i cant do that. (i have no walls in my design) And i dunt think i can put the time i have left into making walls .. Also i'm using the only two pwm's on my 16F877A for my motors.
secondly, i thought the detection would be much more efficient if the transmitter was pointed at the detected instead bouncing of a wall? In the sense that outside interference etc wont affect as much.. someone correct me if im wrong. This is why i thought it was better to have the transmitter as a separate unit.
Also ive heard is setup where IR is used as the path .. so there is a whole stream of IR transmitters say for example along the cieling of a coridoor or on the floor, and the robot basically keeps tracking these emitters .. so im tring to incorporate that style .. of having one detector on the robot and having multiple transmitters external to the robot.
my concern now is when someone said the detector wont stay low the whole time its detecting an IR .. that it would stay low and come back high. i want it to stay long as long as an IR is hitting it .. or do i?
I want to place two detectors on the robot .. one on the right , one on the left. The transmitters will be placed at each turning point of the robots path. (see my attachment) I want the robot to come out of a "forward routine" and jump to a "turn routine" as soon it detects an IR. And yes i can use counters if i need it to make the second turn and so forth. Another concern is I'm gonn have to place the transmitters in such a way that they dunt interfere with each other. So that the robot does not detect the wrong trasnmitter.
Pls give my any input and experience you have with such setups. I have jsut 3 more days to complete this setup before final demo!!!! arggh ..
Thanks so much everyone who is responding to this thread!
