I'm working to build a mobile robot research platform and 
have thus far used dead reckoning (optical encoders on wheels)
to determine the robots global position. The results have been
good but the errors increase as time goes on.

Now, I wish to increase the position tracking accuracy because
the platform will soon need to support a vision platform.

Does any one have any idea where I can get some sort of
tracking device or how others have treated this problem?


Thanks in advance, please send any responses directly to me.
