Where Am I ?

Dave, Based on the size of my back yard/garden the angular resolution i would need is sub-Minute. The longest distance between a possible robot location and a stationary beacon is aprox 108 feet. To get a 0.1 foot location resolution from this distance, I would need about 19 seconds of resolution. A further and more practical problem with the beacon idea is that the garden is in raised beds and fully grown plants can get quite tall. I think the plants could easily reach higher than the scanner on the top of the robot.
You were wondering if this was a Gedanken experiment or other. I had to look up Gedanken, and now i've learned an new word. I suppose that it is a thought experiment leading into an actual want type of experiment. Clearly the easy path would be to get some garden hose, sprinklers and timers. If it is do-able, I am going to try the robot approach just to satisfy an itch.

Csaba, I will take another look at the last figure/diagram in the report.
