RoboJelly, The Unmanned Underwater Vehicle That Uses Water For Fuel A researcher watches RoboJelly, an unmanned underwater vehicle that swims like a jellyfish and uses hydrogen from water as fuel. These are the kinds of jellyfish you don’t need to be afraid of. They look and swim like jellyfish, but they’re actually water-dwelling fuel cells attached to an artificial muscle, and they might just be the answer to a powerful and cheap way to monitor the world’s oceans. RoboJelly is the creation of associate professor Shashank Priya and his team at Virginia Tech’s College of Engineering. This biomimetic robot has a bell-shaped, rubbery skin made of shape-memory alloys that return to their original shape after being bent. The bell’s dimensions are true to that of the Aurelia aurita jellyfish, and it propels itself through the water with the same slow, pulsatile mechanics of its biological counterpart.
Short List of RESTful API Frameworks for PHP Having a web API is an essential part of doing business online today. We wanted to help get you started. So we took some time to pull together a list of the RESTful or RESTish (however you choose to view it) API frameworks, that can help you deploy your API faster. New Video Of Army’s Alpha Dog Robot: “This Thing Is Awesome” No need to wait up. The speedier Alpha Dog now trots over flat terrain at 7 mph. For the last decade now Boston Dynamics has continuously provided some of the best two- and four-legged walking robots on the planet, and they’re continuing this trend with their latest version of Alpha Dog. Most articles about Alpha Dog go kind of like, “Impressive, but man, really loud.”

Meet the Amazing Robots That Will Compete in the DARPA Robotics Challenge Wow. I mean, seriously, wow. We've been incredibly excited to see the progress that Boston Dynamics has been making on ATLAS in preparation for the DARPA Robotics Challenge, but we had no idea what to expect from the challenge's Track A teams, each of whom will be designing and building their own robot with capabilities comparable to what we've seen ATLAS do. Today, October 24, is opening day for the DARPA Robotics Challenge, or DRC.
Drones russes peuvent voir les obstacles July 16th, 2012 defencetalk.com (Voice of Russia) Russia may equip its drones with the so-called “technical vision” device that enables them to see and avoid obstacles, detect small-size objects and assess their potential danger. The system was created by a team of engineers at the Luch designer bureau, who say that it has no analogues in the world. Installed onboard unmanned aircraft, it gives them capabilities that no other existing system can give, the bureau’s deputy chief designer Yevgeny Andriyevsky told the Voice of Russia: “Drones fitted with such a system can do what none of the existing analogues is able to do. They can fly at the lowest possible altitudes over zones with tall buildings and over rugged terrain of which there are no reliable maps and where a flight planning error might lead to the loss of the plane.” The Luch-designed Vozdukhoplavatel (Aeronaut) drone is the only unmanned plane so far to have the “technical vision” system installed on it.
XRobots.co.uk - Micro Helicopter Repair Fortunately there are two gears which are the same in this model of helicopter - one which drives the top rotor, and one which drives the bottom rotor. The plan is to make a mould from the good gear to cast a replacement for the other. Note that I've written to Revell to obtain replacement gears, which they have replied to say are available, although there doesn't appear to be an item to purchase on their website amongst the other spares for this model. I've put the good gear into a box made from clay which will have Silicone RTV poured into it. I'm using Repsil E30, but any bog standard moulding silicone will do: Silicone is poured into the box which makes a negative impression of the gear in the rubber.
Japanese Researchers Continue Quest To Build Life-Like Humanoid Robots In the graphic novel The Watchmen, the physicist Jon Osterman is vaporized in an experiment and comes back as the god-like Doctor Manhattan after meticulously putting himself together again one organ system at a time. In a way, Japanese researchers are doing their own version of this through efforts to create human-like robots, though it’s requiring a much longer time frame to make a person out of metal and plastics. In a recent effort to mimic the human musculoskeletal system, researchers at the University of Tokyo unveiled Kenshiro, a 50-kg robot that has the bones and muscles akin to a 12-year-old boy. The bones are made from aluminum, and the bot has individual ribs as well as floating knee cap (patella). Designing a Secure REST (Web) API without OAuth Situation You want to develop a RESTful web API for developers that is secure to use, but doesn’t require the complexity of OAuth and takes a simple “pass the credentials in the query” approach… or something equally-as-easy for people to use, but it needs to be secure. You are a smart guy, so you start to think… Problem
Researchers create robot exoskeleton that is controlled by a moth running on a trackball If you’re terrified of the possibility that humanity will be dismembered by an insectoid master race, equipped with robotic exoskeletons (or would that be exo-exoskeletons?), look away now. Researchers at the University of Tokyo have strapped a moth into a robotic exoskeleton, with the moth successfully controlling the robot to reach a specific location inside a wind tunnel. In all, fourteen male silkmoths were tested, and they all showed a scary aptitude for steering a robot. In the tests, the moths had to guide the robot towards a source of female sex pheromone. The researchers even introduced a turning bias — where one of the robot’s motors is stronger than the other, causing it to veer to one side — and yet the moths still reached the target.
RESTful API Design: Teach a Dog to REST UPDATED November 2011: Check out the second edition of the webinar - RESTful API Design. It's been 10 years since Roy Fielding first defined REST in his dissertation on Architectural Styles and the Design of Network-based Software Architectures. Since then, REST is often held as the standard for usable, well-designed, easy-to-integrate APIs. At the Cloudstock hackathon, I presented "Teach a Dog to REST," asking the question: where are all the elegant REST APIs we'd all hoped to see? While many claim REST has arrived, many APIs in the wild exhibit arbitrary, productivity-killing deviations from true REST. In this presentation, I start with a typical poorly-designed API and iterate it into a well-behaved RESTful API.
A Self-Folding Origami Robot That Can Walk, Climb, Dig, Carry, Swim and Dissolves into Nothing Scientists at MIT have pulled up a very tiny curtain on their newest invention: a 1.7cm square robot capable of assembling itself like a piece of origami. The Untethered Miniature Origami Robot is powered by a small neodymium magnet and four electromagnetic coils underneath the robot’s surface that create magnet fields necessary for it to operate. The small robot can walk on different surfaces, climb, carry objects twice its own weight, swim in shallow water, burrow, and it even completely dissolves in an acetone solution leaving behind just the magnet. So what can we do with super tiny self-folding robots?
iRobot yields impressive results for DARPA's ARM program DARPA's ARM program hand is flexible enough to pick up a basketball... Image Gallery (10 images) Back when DARPA first announced its Autonomous Robotic Manipulation (ARM) program in 2010, the average cost of a military-grade robot hand was around US$50,000.
