Cool.<br>

I think there was a DPRG guy back in the Science Place days who was
working on an agricultural robot. He had a very accurate GPS system
and made some benchmarks for us. Anyone remember who that was?<br>

<div> It will be interesting how the garden weeder robot pans
out. The $250 cost point would make it affordable enough for a
home owner. I am not so interested in gardening, however I
would be interested in a unit that kept my shrubbery beds
clean of weeds and secondary scrub suckers. It would have to
ride over mulch and eliminate non-scrub/flowers targets.
Keeping landscape beds clean is a major nuisance.</div>

<div> I have both of those books on my shelves. I found them
when I used to search Half Price books for interesting books.
Amazon has them available at reasonable cost. Both are very
good reads and excellent references. The Joesph Jones book
shows up in a lot of college lectures, but is also suitable
for the hobbyist roboticist. It is my favorite of the two.</div>

Joe Jones is starting a kick-starter campaign for a
roomba-style robot to weed your garden:<br>

You may remember Joesph Jones as the author of "Behavior
Based Robotics", which at one time we had in the DPRG
library, back when we had a library:<br>

<br>
as well as, with Anita Flynn, the classic "Mobile Robots"
<br>

which was my first introduction to subsumption. I still
have my original edition, (although my memory is that he
was very unhappy with the second edition, which was
published without his input or approval).<br>
