Robots to build Mars settlement

FOUR sister robots built by NASA could be pioneers in the colonisation of Mars, part of an advance construction team that sets up a habitat for more fragile human explorers. But first they’re finding new homes on Earth and engineers to hone their skills.

The space agency has kept one Valkyrie robot at its birthplace, the Johnson Space Center in Houston. It has loaned three others to universities in Massachusetts and Scotland so professors and students can tinker with the six-foot-tall, 150kg humanoids and make them more autonomous.

One of the robots, nicknamed Val, still hasn’t quite harmonised its 28 torque-controlled joints and nearly 200 sensors after arriving at a robotics centre at the University of Massachusetts-Lowell.

Engineering students let the electricity-powered robot down from a harness and tried to let it walk, only to watch as Val’s legs awkwardly lurched and locked into a ballet pose.

“That doesn’t look good,” said Taskin Padir, a professor at Northeastern University, noting Val’s $2 million price tag.

Northeastern and UMass-Lowell are partnering on a two-year project to improve the robot’s software and test its ability to manipulate tools, climb a ladder and perform high-level tasks.

NASA originally designed Valkyrie several years ago to compete in the disaster-relief robotics contest hosted by the US military’s Defense Advanced Research Projects Agency, but now it’s looking for outside expertise to craft her into a kind of space mechanic.

NASA shipped two other Valkyries to the Massachusetts Institute of Technology and the University of Edinburgh in Scotland.

This is not yet the stuff of The Martian, the Hollywood blockbuster about surviving on the Red Planet. For one thing, the tiny holes that prevent Val from overheating could get clogged up by spiralling Martian dust. But a sturdier exterior will come later.

There is still another two decades before NASA aims to land humans on Mars in the mid-2030s, said Johnson Space Center spokesman Jay Bolden. Now is the time, he said, to build the computer code that will make the robots useful in hostile environments. If not the Valkyries, it will be their descendants serving as the robot vanguard that could make human life possible on Mars.

“It needs to be able to communicate back to Earth, very clearly and concisely, what’s going on,” said Holly Yanco, a computer science professor who directs UMass-Lowell’s robotics centre and is an expert on human-robot interactions.

A time delay between communications from Earth to Mars means humans won’t be able to remotely control robots that will need to build structures and do emergency repair work.
