Subject: [Pyro-users] current robot position
Message-ID: <138315cf0801071400m60e5130dwfcf0abbeeaf02e77@mail.gmail.com>

Hi friends,

I am wondering how can I got the robot current position, in a way the robot
moves taking this into account.
I want to try different brains (fuzzy logic, neural net, ga, etc) on just
one world at time, to compare which one drives more efficient (lest moves)
and fast (least time) the robot from one initial point to a final (goal)
point.
I think to try this as a project course to AI students.

Any suggestion will be welcome.

Thanks in advance.

Jaime,

You can ask any robot where it thinks it is by simply looking at robot.x 
and robot.y. But that is not where it actually is. Real robots have no 
way of knowing that, but you can ask a simulated robot through the 
simulation device:

 >>> robot.simulation[0].getPose("RedPioneer")
(4.9, 1.32, 6.28)

Hope that helps,

-Doug
