Robot, know thyself; machines get more self-aware

Robot, know thyself; machines get more self-aware

NEW YORK: Forget dreaming of electric sheep. Robots first need to figure out how to imagine themselves.
One New York robot has done just that. It’s learned that it’s a robotic arm using a process of self-simulation.
Columbia University engineers have given the robot the ability to model itself without prior knowledge of physics or its own shape.
The robot starts out moving randomly, but over time learns enough about itself to be able to perform tasks and even detect if it’s been damaged.
Columbia mechanical engineering professor Hod Lipson says “self-awareness is the Holy Grail” of autonomy. He says there are ethical risks in gifting robots with self-awareness but also many benefits, including adaptability and resilience.
The research was published last week in Science Robotics.



SpaceX launch moving ahead, weather uncertain

SpaceX launch moving ahead, weather uncertain

  • NASA chief Jim Bridenstine: ‘We are moving forward with launch today’

KENNEDY SPACE CENTER: SpaceX’s historic first crewed mission to the International Space Station was set to proceed as scheduled on Saturday, NASA said, although uncertainty remained over weather conditions.
“We are moving forward with launch today,” NASA chief Jim Bridenstine said in a tweet. “Weather challenges remain with a 50 percent chance of cancelation.”
“Proceeding with countdown today,” said SpaceX founder Elon Musk.
Weather forced the postponement on Wednesday of what would have been the first launch of American astronauts from US soil in almost a decade, and the first crewed launch ever by a commercial company.
The Falcon 9 rocket with SpaceX’s Crew Dragon capsule is scheduled to launch at 3:22 p.m. Eastern Time (1922 GMT) on Saturday.
The next window, which is determined by the relative positions of the launch site to the space station, is Sunday at 3:00 p.m. (1900 GMT), and fair weather is predicted.
NASA astronauts Bob Behnken, 49, and Douglas Hurley, 53, former military test pilots who joined the space agency in 2000, are to blast off for the ISS from historic Launch Pad 39A on a two-stage SpaceX Falcon 9 rocket.
The same launch pad was used by Neil Armstrong and his Apollo 11 crewmates on their historic 1969 journey to the Moon, as NASA seeks to revive excitement around human space exploration ahead of a planned return to Earth’s satellite and then Mars.
The mission comes despite shutdowns caused by the coronavirus pandemic, with the crew in quarantine for more than two weeks.
NASA has urged crowds to stay away from Cocoa Beach, the traditional viewing spot — but that did not deter many space fans on Wednesday.
President Donald Trump, who flew in for the previous launch attempt, is expected to attend again.
