Who we are
Team Overbot is an all-volunteer effort. We're a group of senior engineering
people in Silicon Valley. Many of us are Stanford alumni, though one of
us went to MIT. All of us have done previous robotics, navigation, or
related work. Most of us have been through a high-tech startup; some of
us have run them.
Why are we doing this? Our motives vary. But we all see that it's possible
to do this. We have the technology. It could be the next big thing. That's
how Silicon Valley makes things happen.
2682 Middlefield Road, Unit N
Redwood City, CA 94063
We're located in the Redwood Junction industrial park in Redwood
City, California, about 0.4 miles east of Woodside Road.
Take US 101 or I-280 to Woodside Road. Go to Middlefield Road.
Turn south. Turn into Redwood Junction at the railroad crossing.
We're in the first building in the industrial park, on the far side.

We're always glad to talk to
the working press.
How does it work?
The simplified version:
We bought the fastest available commercial 6 wheel drive ATV, and put
electric motors on the steering, throttle, shifter, and brake. We put
a scanning laser rangefinder and a TV camera on top, a radar on the
front, and a few other sensors around the vehicle. All these connect
to computers, five of them.
DARPA gives us a CD-ROM two hours before the race with about 1000 GPS
waypoints. Those give us a general idea of what the route is, but we
have to deal with the real world along the way. If the waypoints put
us on a road, the vehicle follows the road; if we're off-road, the laser
rangefinder profiles the ground ahead, and looks for reasonably flat
places to go. On tough terrain, the vehicle slows down, shifts to low,
engages six wheel drive, and grinds its way through. If there's an obstacle
or the terrain becomes impossible to drive over, the vehicle backs off
and looks for a better route.
The technical version:
In EE380, at Stanford,
on September 24, 2003, we gave a technical presentation.

Public technical documents
As time goes on, we'll open up more of our design documents and code
to public access. For now, we offer a small archive.
