I would think a robot would only get in trouble if it had a green stripe of approx the same height and width as the tetra and the same altitude and texture. What I am saying is test like crazy to be sure.
Excellent point.

It will be difficult to test like that when you're concerned about other robots, though.

Think about it--that robot followed Dave around, and it also followed the green tetra, if I'm not mistaken. Those were wildly different greens.
