Swarm robots form landing pad for quadrotor. I love swarm robots, especially when they pull off tricks that you can easily imagine a robot army doing.
Researchers at the Georgia Robotics and Intelligent Systems Lab have been having fun with small Khepera robots and a quadrotor. Ted Macdonald and colleagues previously taught the rolling bots to spell the lab's acronym, GRITS, as seen in this video. Now they've made the bots form a mobile landing platform for the quadrotor. The vid below shows how the Khepera robots can be told to follow a leader bot and assemble into various formations.

College students amassing piles of money to pay for textbooks this fall may get a reprieve with a new Amazon rental program that gets them up to 80 percent off list prices.
Kindle Textbook Rental allows students to rent textbooks and read them via the free Kindle reading apps, with book annotations preserved in the cloud storage after the rental period is up. With Kindle apps available on several platforms—PC, Mac, iOS, Android, Windows Phone, and Blackberry—students who rent from Kindle Textbook Rental will have a number of offline viewing options. Students can choose their rental period as well, from 30 to 360 days. As rental periods get longer, the price goes up, almost prohibitively so. While the rental price of books in the $100-120 range start at around $40, that cost can more than double for a semester-long rental to $80. Gen Y’s Luxury Buys: Young People Crave Designer Brands.

Saturday's New York Times contained an interesting op-ed piece by Charles Blow, titled "American Shame.
" The main item was a table listing the 33 countries designated as "advanced economies" by the International Monetary Fund and comparing them on various social and educational characteristics. Specifically, Blow charted income inequality, unemployment rates, level of democracy, the "percentage thriving" (according to the Gallup Global Well-Being Index), food insecurity, prison population, and student performance in math and science.
The bottom line: The United States is at the bottom of the heap on most of these measures, and at or near the top in none. It's a sobering collection of data, to be sure, but I wish Blow had added two more columns to his chart: 1) percentage of GDP devoted to defense, and 2) defense spending per capita.
