The ATHLETE
(All-Terrain Hex-Legged Extra-Terrestrial Explorer) robot could play an essential
role in new lunar bases.
According to NASA, the 15 ton lunar habitat would be mounted
on top of the six-legged robot. The habitat could walk right off of the lunar
lander, and then proceed to any desired location. Wheeled locomotion would be
used for level ground; more challenging terrain could be negotiated with the
full use of the flexible legs.
The ATHLETE-based
habitat could then be controlled directly by astronauts; mission control could
also direct the habitat from Earth. My favorite alternative, an autonomous
robot habitat, is also slated for testing. It would use software developed for
the Mars
rovers Spirit and Opportunity.
The robot habitat would move around using power drawn from
solar arrays; the maximum speed is about 10 km/hour. Although this seems slow,
remember that the Moon's circumference is just 11,000 kilometers (compared to
Earth's circumference of 40,000 km). Astronauts would live a nomadic existence,
covering much more of the lunar surface.
NASA engineers are testing two prototypes of the robotic
lunar base in Pasadena, CA.
Abandoning the idea of a fixed lunar base would be a huge
shift for NASA (and maybe the rest of us). Instead, astronauts would lead a
nomadic existence; this would let them cover vastly more ground in exploration.
Even better, the robot habitat could even help out; take a
look at this video
of the ATHLETE robot attaching tools to its flexible legs Transformer-style.
The ATHLETE-based lunar habitat reminds me of two
science-fictional devices. Jack Vance wrote this about a walking fort in his
1964 novel The Killing Machine:
He wanted Patch to design and construct a walking fort in
the semblance of a monster centipede, seventy-six feet long and twelve feet
high. The mechanism was to consist of eighteen segments, each equiped with a
pair of legs...

Once NASA settles down and starts working on future designs,
perhaps a walking lunar base might resemble this "crab fort" drawn by
Daniel Dociu (see picture).
In terms of movement, it reminded me of the slow-but-steady steel tortoise,
from Robert Heinlein's 1940 novella Coventry; this vehicle was also
solar powered, and crawled along at a top speed of just six miles per hour.
This is a big change from the static location moon base;
this idea has been a staple of science-fictional Moon exploration since the moon domes of Ray
Cummings 1931 novel Brigands
of the Moon.
