Creepy Two-Legged Robot Walks Like a Human

It's not going to win any foot races, but a new robot being developed for the U.S. Army still has a leg (or two) up on its competition. The "Petman" prototype is a bipedal robot that simulates human walking (video after the break) more realistically than any other robot we've seen. According to Wired, the robot, which is being developed by Boston Dynamics, will be used to test how protective clothing responds during chemical warfare. It walks with a heel-to-toe motion at 3.2 mph and can maintain balance if pushed or bumped. Plus, the robot simulates human environmental and physiological factors -- like temperature, humidity, and "sweating" -- to provide even more realistic testing conditions.

There's a slew of walking robots out there, but "Petman" stands out in the crowd. It's hard to pinpoint what's most amazing -- the 'bot's balance or the walking motion. Just as long as the Army is really using "Petman" to test clothing, and creating a plethora of robot super soldiers. [From: Wired]

Who Needs Teachers When You've Got Robots to Grade Essays?

Britain to Start Marking English Exams with Robots
Automated test scoring is nothing new. Most of us are quite familiar with the act of filling in little #2 pencil marks on a Scantron, and having it fed through a machine that puts a depressing little red dash next to each wrong answer. That's all well and good for tests with simple multiple choice answers, but what about tests with written answers and essay questions, like an English test? Well, Pearson, an America-based education company, will be debuting a new English proficiency exam given to students seeking admission to British universities.

The Times Educational Supplement (TES) reported that Pearson had developed an artificial intelligence program that can assess the use of grammar and vocabulary in essays. A representative from Pearson told TES that the system was just as accurate as a human marker, but removed variables like fatigue and changes in mood. The program was created by analyzing how human scorers marked tests, but academics, teachers, and common sense says that a machine will never be able to pick up on the small quirks that make for quality writing.

Denmark to Allow Internet Use During Exams


Politiken is reporting that several high schools in Denmark will be allowing 'A' level students to have Internet access during their written exams. If the experiment goes well, the system will be implemented across the country for the 2011 high school exams.

According to Politiken, the Ministry of Education will require that papers be handed in digitally, and administrators will carry out random site checks to curb plagiarism and cheating.

We love this idea. Before you cry foul, remember that there was a time when calculators weren't allowed to be used in tests. School is about preparing students for the real world, and these days the Internet allows information to be obtained at the blink of an eye. Plus, we think this is excellent training for an entirely new generation of bloggers. Long live the hyperlink! [From: Politiken]

Southwest Details In-flight Wi-Fi Plans, Yahoo! Partnership


Southwest got official with its Wi-Fi plans late last month, but avid travelers who favor the only airline worth flying anymore (okay, Virgin America and JetBlue aren't bad either) were left wondering about most of the details. Today, the company has fired up a single Row 44-equipped flight, and it has announced plans to equip three more airplanes with in-flight WiFi by early next month. Furthermore, it has nailed down a partnership with Yahoo! in order to offer an in-flight homepage with "destination-relevant content." The service, which has yet to receive final FCC approval, will be tested over the next few months, and if all goes well, we're left to hope, pray and beg that the airline rolls it out fleet-wide. There's no mention of an actual price here, but it would totally rule if it bucked the trend and provided it to everyone for free. Right, everyone? [Via Gadling]
