thinker sends in an MSNBC report on the development of ethical guidelines for battlefield robots. The article notes that such robots won't go autonomous for a while yet, and that the guidelines are being drawn up for relatively uncomplicated situations — such as a war zone from which all non-combatents have already fled, so that anybody who shoots at you is a legitimate target. "Smart missiles, rolling robots, and flying drones currently controlled by humans, are being used on the battlefield more every day. But what happens when humans are taken out of the loop, and robots are left to make decisions, like who to kill or what to bomb, on their own? Ronald Arkin, a professor of computer science at Georgia Tech, is in the first stages of developing an 'ethical governor,' a package of software and hardware that tells robots when and what to fire. His book on the subject, Governing Lethal Behavior in Autonomous Robots, comes out this month."

CNETNate writes "To advance its Street View service this summer, Google is poised to unleash the unstoppable power of human legs. Google will deploy pedal-powered tricycles — the company calls them 'Google Trikes' — mounted with 360 degree Street View cameras to map areas inaccessible by its fleet of Street View cars." The article indicates that the trikes will first see use in the UK, to map out public walking paths, but one anonymous commenter said: "This must be bogus — you are not allowed to cycle on public footpaths in the UK, I can't believe Google would have overlooked such a fundamental fact. Not to mention that the vehicle pictured wouldn't fit down most paths." PC World features the trikes in Rome.

Kelson writes "Google's Mountain View headquarters has fields that need to be kept clear of fire hazards. This year instead of mowing them, they took a low-carbon approach: they hired a herd of goats to eat the grass for a week. 'It costs us about the same as mowing, and goats are a lot cuter to watch than lawn mowers,' wrote Dan Hoffman."
