- We use Denning robots and are faced with a similar nightmare. One of
- the things we're working on at the moment involves using visual homing
- techniques to essentially recalibrate the robot at various points in
- the environment, and coupling that with motion planning. I'd have to
- agree with the other posters in that the best we can hope for (at
- least in the case of the Denning) is some bound on the slippage, and
- to take advantage of that bound when we can.
