Robotic Lunar 'MoonDigger' Bulldozers Planned By NASA

Lunar bulldozer robots may perform site preparation for moonbases. A NASA-sponsored study, prepared by Astrobotic Technology Inc. with technical assistance from Carnegie Mellon University’s Robotics Institute, was presented last Friday at a NASA Lunar Surface Systems conference.

“NASA faces a challenge in planning the layout for its outpost, which is expected to begin operations in 2020,” said Dr. William “Red” Whittaker, chairman and chief technical officer of Astrobotic and a Carnegie Mellon professor of robotics. “For efficient cargo transfer, the landing site needs to be close to the outpost’s crew quarters and laboratories. Each rocket landing and takeoff, however, will accelerate lunar grit outwards from the pad. With no atmosphere to slow it down, the dry soil would sandblast the outpost.”

Two potential solutions to the problem were examined: 1) creation of a berm around the landing site and 2) creation of a hard-surface landing pad using lunar materials.

The research team determined that 2 MoonDiggers weighing about 330 pounds apiece could work together in building a suitable berm in just six months. A berm 8.5 feet tall in a 160-foot semi-circle would require moving 2.6 million pounds of lunar 'dirt.'

Utilizing the second of the two alternatives mentioned above requires that the small robots comb the lunar surface for rocks, gathering them for a durable grit-free landing space.

The robotic lunar bulldozers would not be operated by astronauts; instead, the robotic 'dozers would be directed by a combination of direct teleoperation and supervised autonomy by workers on Earth.

This idea is old hat for Pournelle and Niven fans. In their 1981 novel Oath of Fealty, they describe a telepresence bulldozer for just this kind of work.

"Meet Rachel Lief," Lunan said. "Ms. Lief is a bulldozer driver." Lunan paused for effect. "As you see, Ms. Lief doesn't look like your typical tractor driver..."

"But then," Lunan said, "not every bulldozer operator works on the Moon." The cameras followed the trim woman into another room, where there was a replica of a large tractor. It was surrounded by TV screens. One screen showed an astronaut sitting in the driver's seat, staring impatiently into the screen. A bleak, nearly colorless pit showed over his left shoulder.

"About time you got here," the astronaut said.

"We were busy," Rachel sat down in the driver's seat and took hold of the controls. "I relieve you..."

The bulldozer moved through the lunar strip mine...
