Re: Reflected Signal Problem

[Joyce Poon <poonj@ecf.utoronto.ca>]

Yes... but the problem I was referring to was how we can tell whether the
signal we are reading is actually a reflection of the signal emitted by
the enemy beacon placed on top of our robot.

Ie
	mirror
	---------------------
		|
		|
		|

		|
		0
	0 = our robot
	| = IR beam emitted from the enemy beacon

If we are in the pursue mode, we will be trying to chase ourselves.
If we are in the evade mode, we will be trying to run away from ourselves.

Again, this reflected beam problem can be partially resolved
algorithmically (as Tim pointed out at breakfast).

The problem that Cindy described is neglects the fact that we may be
picking up the signal emitted by the enemy beacon as well.  It will be all
good if we can just read 1 signal... but the question now is... whose
signal is it?
