Graphite has been known as a typical diamagnetic material and can be levitated in the strong magnetic field. Here we show that the magnetically levitating pyrolytic graphite can be moved in the arbitrary place by simple photoirradiation. It is notable that the optical motion control system described in this paper requires only NdFeB permanent magnets and light source.
The optical movement is driven by photothermally induced changes in the… read more

CRNS-AIST Joint Robotics Laboratory researchers are developing a brain-controlled interface (BCI) that would allow tetraplegics or paraplegics to remotely control robots via thought alone.
Using a cap with electroencephalogram (EEG) electrodes, a computer program would interpret the user’s brainwave signals and transform them into robot actions to control movement and interaction.

The new Parrot MiniDrone is a miniaturized version of the AR.Drone quadcopter, at about a tenth the size.
An optical flow camera, sonar rangefinder, and computer allows it to sense how high it is off of the ground, and using optical flow, sense its own motion relative to the ground. This, with the assistance of a barometer, accelerometer, and gyro, enables the MiniDrone to self-stabilize.
It… read more

PBS Newshour | Teaching computers how to play Atari better than humans.
This version of Atari’s “Space Invaders” isn’t being played by a person, but a system of computer algorithms that is learning how to play it just by looking at the pixels on the screen.
PBS NewsHour | Science correspondent Miles O’Brien goes head-to-circuit board with IBM’s computer Watson on the game show Jeopardy! to explore the limits of language and artificial intelligence for machines. Interviewed in this segment: Ray Kurzweil (author, inventor), David Ferrucci (IBM), Marvin Minksy (MIT, AI expert). In the second video, Miles O’Brien takes on Watson, and loses. In the third video, he tells Hari Sreenivasan about how the supercomputer works… read more
