I've been playing with solar for power (the walkers don't have to move very fast) and the solar panels will also be the light sensors. The panel with the most light will be the direction the walker will take. Water is trickier. I've been thinking about using polarized light and an SLR. Take a picture using a polarized filter and one w/out. Find the dif. between the two. Water should reflect at a specific wave length some where in that dif. but its all theory. If you guys have any thoughts on water finding let me know. Remember, it has to be directional, hydrometers wont work.
I've been toying with the idea of having the rovers ask for water. Since they will be deployed in an urban setting, it is possible that people would water the garden when asked. Or, at worst, vandalism.

What will power your garden walkers to move?
How will they actively seek out light and water?
