They have now been added to the links page. I've also added another
robot lawnmower site I found a few days ago.

A cheap mobile platform is the holy grail of amateur robotics, unless
you consider $300 cheap ;-) I'm seriously thinking about getting some of
those motors from All Electronics Corp and giving them a go. I was going
to use the drive system from my old Hero Jr (a stepper steered, DC
driven wheel, but there are some positional problems I don't want to
face yet.
The part I need to interface the Weed eater head to my motor is being
finished today, so I should have pictures of the experiments on the web
by Tuesday next week.
And the ultrasonic sensor system is working excellently, I have a few
more mods and experiments to make before I commit it to the site. I
found a cheap source for transducers here in Sydney that will allow me
to extend it significantly. The original transducers I bought cost $10 a
pair, I have found a source at $3 a pair.
I think I've found a good source for the inclinometer system also,
Servo-Gyros. They are used in RC helicopters to stop the chopper
spinning around in a circle. Two of these will provide 3D incline
information.
