In robotics you're only limited by your Imagination... well, it helps if you have several skills, money, and time!
It all starts with an idea.
Here's what we need... a "earth rover". A small track vehicle equipped with with search coil... for gold.
This little critter will look for gold nuggets in areas like the southwest... or even the Australian Outback.
We just take it out to a location, turn it on, come back a week later, or so.
The little bot is tracked on your home computer, current location, if moving, number of targets found and location of each.
You could also over-ride the automatic control to direct it in a different direction. Or use the on-board camera to look around.
The bot also downloads all data to memory chips so info can be recovered at the bot. It also marks the ground with fluorescent orange paint, target at one end of line marked. Makes it easier to find if your GPS is off some.
It could even phone home to tell you about any trouble or problems... "My batteries are 28%, my run time is 3 hours, 22.5 minutes."
... "I have been "BOT-NAPPED, I'm moving southeast on Hwy 38 at 52 mph, you can send two-way voice message at this time."
No Limits!!
