That's why I'm doing the experiment Monta, so *I* can be sure!

No we wouldn't, we'd have to distinguish between hard and soft surfaces.
This sensor isn't meant to be everything, it's one of perhaps many.

That's why I'm not. I suggest you review the results of positional work
related to robots to date. Pay close attention to the fact that the best
performers all required specialised environments.
What we have to produce is a robot that responds to the world, not a
disjointed fusion map of the world, not an uncertainty grid, not a cost
grid. This is a real-world project.
