Optical motion control of maglev graphite

December 31, 2012

maglev_graphite

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

SpaceX Grasshopper 12 story test flight

December 25, 2012

Grasshopper

SpaceX’s Grasshopper — a 10-story vertical takeoff and landing (VTVL) vehicle — took a 12-story leap towards full and rapid rocket reusability in a test flight conducted December 17, 2012 at SpaceX’s rocket development facility in McGregor, Texas.

Grasshopper rose 131 feet (40 meters), hovered, and landed safely on the pad, using closed-loop thrust vector and throttle control. The total test duration was 29 seconds.

Grasshopper consists of… read more

AIRobots: remotely controlled aerial robots

December 24, 2012

airobots_twente

The University of Twente AIRobots project is developing a new generation of remotely controlled “aerial service robots” (a.k.a. drones). The researchers plan to use virtual reality, augmented reality, and haptic (touch) devices to allow the operator to guide the robot while hiding the complexity of the vehicle dynamics.

lego_quadcopter

Nicholas and Joshua Scott, with help from their father Ed Scott, have designed “the world’s first flying robot made out of Lego.”

According to Gary Mortimer in sUAS News, the quadrocopter is equipped with a Go Pro camera, offering a first-person-view camera, and a transmitter sends back live video images to its pilot. It is kept on an even keel and able to navigate waypoints via GPS thanks to an APM 2.5 autopilot from… read more

Space bursts provide insight to Theory of Everything

December 11, 2012

space_bursts_video

Light from some of the universe’s most energetic explosions is allowing scientists to probe the nature of space-time, according to new observations of gamma-ray bursts from the Japanese Aerospace Exploration Agency’s Ikaros spacecraft. Photons released by these bursts help place limits on a unified model of all of the forces of nature — what scientists call a “theory of everything.”
