Why isn't there a garden robot?
About the most we have today are drip watering systems with automatic timers.
There aren't even commonly available systems that measure and react to the
actual water content in the soil (see the "green thumb" below).
They can fly a camera on three winches over a football field, why can't we
rig up a hose, seed and rabbit pellet dispenser, micro weed eater, and camera?
How about a social web site that shows an overhead picture of your garden
and invites people to play a "game" of nuking your weeds, complete with CGI
explosions of the targets. The aggregate result, less protected areas where
you know there are plants, can direct the robot to weed the area.

the lighting cycle and reminds the user to add water and nutrients as needed.
The roots are held in air at 100% humidity (no dirt). Cost is about

gardens with the grow light in the center said to decrease growing time.
The "Telegarden" was a remote operation experiment over the internet.
Hanging planters with a wick style automatic watering system
Wicking beds turn standard raised bed gardens into self watering, super low
water use, huge earthboxes! Imagine a standard raised bed frame, then put
a plastic or rubber liner inside, making a sort of pool. Next, put "agi-pipe"
(used for building soil drains) along the bottom, connected to a plastic
elbo and a stand pipe. Fill in a few inches of gravel or "screening rock"
and cover with shade cloth or old sheets to keep the soil from invading the
space between the rocks. At one end, cut a "drain hole" in the liner so the
water can never rise above the rocks. Finally fill in soil, compost, and
mulch as always. Fill with water from the stand pipe until it starts to seep
from the drain hole. Now the bed will be watered for weeks on end, and no
water will touch the surface, preventing oportunistic seeds from rooting
and keeping the mulch and compost soft and easy to work. The water also will
not seep into the soil below the bed, so much less water is used.

A "wirebot" can hang above a garden on three poles and "fly" over the plants
taking pictures for remote review, probing the soil for moisture level, and
if fitted with a gripper or something like the "Awecome
could remove weeds, dig small holes to plant seeds, etc... The instability
of the wirebot head can be improved by running /two/ wires from the head
to each pole, one high and one low holding the head top and bottom.

A tip to take into consideration though is to tape or paint the outsides
opauqe to prevent algae growth and promote healthy root development.This
is because algae like light and suffocates the roots by covering them and
stealing nutrient etc. And the roots become stunted on some plants because
they strive to avoid the light and by doing this they bunch up in the middle
of the planter.
We made these from old laundry soap jugs (the really big ones) and sent kids
home from RE classes with tomato plants. The handle is a perfect place to
shove a small, dead bush for a latice. The kids don't have to remember to
water them more than once a week or so.
