Autonomous quadrotor flight
21 Sep 2010
Quote From TheDmel “Control of precise aggressive maneuvers with an autonomous quadrotor helicopter. This is a small autonomous Unmanned Aerial Vehicle (UAV). Demonstrations of flips, flight through windows, and quadrotor perching are shown. Work done at the GRASP Lab, University of Pennsylvania.”
Quote From frankerssj “We designed a system that is capable of autonomous navigation with real-time performance on a mobile processor using only onboard sensors. Specifically, we address multi-floor mapping with loop closure, localization, planning, and autonomous control, including adaptation to aerodynamic effects during traversal through spaces with low vertical clearance or strong external disturbances. All of the computation is done onboard the 1.6Ghz Intel Atom processor and uses ROS for interprocess communication. Human interaction is limited to provide high-level goals to the robot.”
This work was done by Daniel Mellinger, Dr. Nathan Michael, and Professor Vijay Kumar.

Bill Murray Talks About Gostbusters 3
21 Sep 2010
Excerpt From gq.com : Interview by Dan Fierman
DAN—Is the third Ghostbusters movie happening? What’s the story with that?
BILL—It’s all a bunch of crock. It’s a crock. There was a story—and I gotta be careful here, I don’t want to hurt someone’s feelings. When I hurt someone’s feelings, I really want to hurt them. [laughs] Harold Ramis said, Oh, I’ve got these guys, they write on The Office, and they’re really funny. They’re going to write the next Ghostbusters. And they had just written this movie that he had directed. more »

DIY-Portable 1.25kJ Coilgun by Larsplatoon
21 Sep 2010
Quote From Larsplatoon “After 2 long years of on-and-off work my coilgun project is finally completed. For anyone who doesn’t know what a coilgun is, it’s a gun that fires a projectile with magnetic force instead of gunpowder. The projectile from this gun won’t kill a person, but the electrical energy stored in the capacitors is 78 times the lethal amount for human beings so this is no toy.
To answer a question that’s been asked quite frequently:
1.25kJ is the electrical energy stored in the capacitors, according to the equation E = 0.5*C*V^2. For this gun, C=15600uF and V=400V, thus E = 1248J. One of the main drawbacks for coilguns is EFFICIENCY, which, for single-stage hobbyist designs (like mine) is limited to about 3%. So if we assume a 3% efficiency, the kinetic energy (delivered to target by projectile) is in the area of 37J, which is much more than a bb gun but much less than a real gun. I don’t have the equipment to measure the kinetic energy (scale and chronometer), but as soon as I do I will report it.”
