Dear discuss-lfm members,
The connection between the Mars Rover, Sojourner, and this
robotic rover caught my eye as well as the NASA Ames involvement.

RELEASE: 97-136
NASA, CARNEGIE MELLON UNIVERSITY TO TEST
ADAPTABLE MOBILE ROBOT IN SOUTH AMERICAN DESERT
From laboratories and a science center in North America, a
group of NASA and Carnegie Mellon University scientists will
control a robotic rover this summer as it explores a desert in
South America to learn more about driving automated vehicles on
Mars and the Moon.
During the 45-day field experiment from June 15 to July 31,
scientists from NASA's Ames Research Center, Moffett Field, CA,
and Carnegie Mellon's Robotics Institute, Pittsburgh, PA, will
conduct an unprecedented 120-mile robotic trek in the Atacama
Desert in northern Chile. The scientists will test the ability
of the robot, nicknamed Nomad, to navigate, explore and perform
science tasks remotely.
"The primary objective of the Atacama Desert trek is to
develop, evaluate and demonstrate a robot capable of long
distance and long duration planetary exploration," said David
Wettergreen, NASA Ames project manager.
"During different phases of this test, we will configure
the robot to simulate wide-area exploration of the Moon, the
search for signs of past life on Mars and the gathering of
meteorite samples in the Antarctic, which makes for a really
unique and challenging experiment," said Dave Lavery,
Telerobotics Program Manager at NASA Headquarters, Washington, DC.
Chile's Atacama Desert, a cold, arid region located above
7,000 feet, was chosen for the field experiment because its
harsh terrain is analogous to that found on Mars and the Moon.
The desert's barren landscape features craters, rocks and loose
sand without any vegetation due to the lack of rain.
"This site is pretty much what we expect to find on Mars,"
said Nathalie Cabrol, the expedition's NASA science team
leader. "Our goal is to simulate several NASA planetary
exploration missions, and this will provide some good training
for future missions," Cabrol added. The desert trek also will
test and validate tools and techniques that NASA has been
developing for future planetary missions.
Nomad was designed and built by researchers at Carnegie
Mellon's Robotics Institute. About the size of a small car,
the robot weighs 1,600 pounds and features
four-wheel drive/four-wheel steering with a chassis that
expands to improve stability and travel over various terrain
conditions. Four aluminum wheels with cleats provide traction
in soft sand. Power is supplied by a gasoline generator and
enables the robot to travel at speeds up to 20 inches per
second. Nomad also contains onboard navigation sensors and
computers to enable it to avoid obstacles without relying on a
human operator.
Nomad's unique onboard panospheric camera provides live
360-degree, video-based still images of the robot's
surroundings. The images will be displayed on large screens at
Ames and Carnegie Science Center in Pittsburgh, where the
public will have an opportunity to control the rover every day
throughout the trek. The rover carries additional color video
cameras to provide stereo vision for detecting obstacles and
high-resolution color video cameras for experiments in remote
geology to be conducted by NASA.
The total cost of developing Nomad and conducting the
desert trek is $1.6 million. The project is funded by NASA
with in-kind support from corporate sponsors and educational
foundations. Information about the desert trek and live images
and data from Nomad will be available on the Internet at URL:
