- Description: ATHLETE (All-Terrain Hex-Legged Extra-Terrestrial Explorer) is a
large six-legged robotic lunar rover under development by
NASA.
The first prototype is greater than 4 meters in diameter
with more than 6 m reach, and is designed to be able to both roll
and walk for maximum efficiency over a wide range of terrains. The
ultimate goal of the project is to develop a multi-purpose system
capable of docking or mating with special-purpose devices, including
a launchable/releasable grappling hook, refueling stations,
excavation implements, and/or special end effectors. The legs have 6
degrees of freedom for generalized robotic manipulation. Each
ATHLETE is intended to have a payload capacity of 450 kg, with the
capability of docking multiple ATHLETE vehicles together to support
larger loads.
The projects goals are
* Able to move at 10 km/h
over terrain similar to that found at the Apollo landing sites
*
Climb vertical steps of at least 70% of the maximum stowed dimension
of the vehicle
* Climb slopes of 35° on rock and 25° on soft
sand
* Be stowed and docked compactly for launch into an annular
ring so that many vehicles can be efficiently stacked around a main
payload on a single lander
* Self-deploy from compact storage on
lunar landers
* Traverse almost any terrain, including vertical
rock faces or sandy slopes at the angle of repose by using a
launchable/releasable grappling hook
ATHLETEs purpose is to
support lunar exploration operations. One hypothetical mission
scenario features a mobile manned base supported by ATHLETEs,
capable of traversing thousands of kilometers and setting down
temporarily to study interesting features along the way.
