Does the sensor in 7 detect the beacon type and 1,2,3, and 4 home in on it?
Thank you in advance.

The default tracker code is actualy very dumb. First it locates the beacon by scanning. The way it finds it is when both sensors on an "eye" finds it, it assumes its dead ahead. When both "eyes" find it, it assumes its there, turns the robot to face it and drives. If it looses it, it stops then scans again. This is actualy a very poor way to do things. If you have good enough programers, you can make it constantly scan and compare and have a more accurate possition. The only problem is that the default code includes no trig functions and you will have to program your on.
On the subject of possitioning, if you use the default tracker code, you could put them pretty much anywhere, though you may need to do some tweaking of speed and sensitivity. The code has comments that tell you where to plug in the sensors too. Its actualy ports 3-6 by default. Seven is actualy defaulted to a switch that chooses what beacon to home in on. The way it works is both beacons emit a different signal (I cant remember what one is which) and the port 7 toggel chooses what one to follow and what one to ignore.
Calling the refs "zebras" is just fine. Just don't call 'em late for dinner (or visually impaired). - EricH [more]
