Video: Alex Shvonski A mass hangs from two identical springs. First, the springs are attached in series by a short string between them. The center string is cut, changing the system from series to parallel.PROBLEM: People who want to program robots have had to either write software from scratch or purchase proprietary software that is hard to modify. SOLUTION: Brian Gerkey has developed open-source platforms, called Player and ROS, that standardize the basic software used to control a robot. Both have been adopted by thousands of companies, universities, and governments around the world.
TR35: Brian Gerkey, 34 - Technology Review
Students at the University of Maryland’s Clark School of Engineering have turned to nature to create a flying device that can hover and perform surveillance duties, and that could lead to applications for military and emergency services. The enigmatic maple tree seeds (or samara fruit) - and the unique spiraling pattern with which they glide to the ground - have intrigued children and engineers for decades. Now aerospace engineering graduate students have applied the seeds’ design to airborne devices and created what they believe to be the world's smallest controllable single-winged rotocraft. Researchers first tried to create an unmanned aerial vehicle that could mimic a maple seed's spiraling fall in the 1950s.

These days, there are few things more valuable than finding your virtual doppelganger--a "friend" who shares many, if not most, of your tastes and traits. On Last.fm , his scrobbles reveal catchy new songs. On Twitter , her tweets reveal interesting new articles. And on personal-finance site Bundle , which launches today, his spending habits reveal invaluable savings tips. "We've all wondered what our co-workers make, and how in the world our constantly broke friend can afford those three-week vacations," explains founder and CEO Jaidev Shergill. "That's okay.
