Find a place where there isn't anybody operating, or there are very few competitors, then do something better than all your competitors.

If you're going into military/police-use robots, you're looking at competing against Foster-Miller's Talon, along with iRobot's Packbot. You have to do something that they can't, or do what they do better than they do. If you can't do that, then you won't be successful with the business.

On the other hand, if you develop something that works with both, that neither has come up with...Well, I can see some success there, at least for a while.
