Look, this top ten celebrity child-rearing tips list of ours is gonna make it to the top, we just know it, and we're tired of hitting up family members to get stories out of the single digits. Luckily there's a better way. The robotic Digg arm -- which appears to be slightly or entirely fake -- refreshes a page, detects Digg badges on the screen, and then moves the cursor over them to "manually" Digg the stories. Apparently the bot can Digg 1500 stories a day, but we're gonna need some more evidence than this joke vid (embedded after the break) to be convinced of this bot's actual, welcomed existence.

While mind-control interfaces are all well and good, sometimes a simpler solution makes a bit more sense, and that's where this so-called Copycat Arm comes in. Developed by a group of researchers at the University of Tsukub, it makes use of a high-speed camera to monitor a person's movements, which are apparently instantly (and creepily) mimicked by the robot arm.Eventually, the researchers say the same system could be used as a computer interface, which they say could eliminate the need for a mouse and keyboard. Unfortunately, there doesn't appear to be a video of the arm in action, but those heading to SIGGRAPH 2008 will apparently be able to check it out first hand.

Oh yeah, we've seen our fair share of robotic arms, but it's not everyday that a craftsman posts an eight-page tutorial on how to construct one of your own for less than $60. The Wooden Menace was designed to show that an inexpensive robotic arm could indeed be constructed using household junk and a few store-bought parts, and while its utility is relatively limited, there's a certain level of cool to having such a device guarding your paperwork at the office. Aside from a cloned PS1 controller and a few hunks of wood, you'll only need a voltage regulator, microcontroller, five servos, a 20MHz oscillator and a few other parts to make it all come together. No need in giving you the run down here -- there's eight pages chock full of details (videos included) awaiting you in the read link below.

Thought-controlled appendages are far from new, but an international team of researchers have apparently created an apparatus that aims to make the lives of paralyzed individuals a tad easier. The Brain2Robot project utilizes electroencephalograph (EEG) signals in order to give patients the ability to control a robotic arm, which could eventually be used to do everything from hold periodicals to lift a cup of coffee. Reportedly, the arm could be ready for commercial use within just a few years, but there's no mention of an expected price range. Granted, we'd be a bit more excited about all of this if the technology were somehow made mobile, but it's hard to kvetch about a helping hand, regardless.

Yeah, we've seen some pretty fancy robotic arm work already this year, but Festo is out to show 'em all up with its fluidic muscle-packin' Airic's_arm. This robotic prosthesis sports a "bone structure" which mimics that found on a real live human, and can be moved via the 30 "muscles" built within. Essentially, Festo's approach to movement relies on "an elastomer tube reinforced by aramid fibers, which contract quickly and exert a pulling force when they're filled with a blast of compressed air or liquid." Of course, you'll notice it doesn't offer quite the same range as less bionic alternatives, but this thing's pretty accurate, indeed. Check it out for yourself, the video's right down there.

Researchers at the Johns Hopkins University Applied Physics Laboratory, no strangers to reaching for seemingly unattainable goals in medical science, have set their sights on what some consider to be the ultimate pursuit of modern prosthetics: a bionic arm that moves, looks and feels like its human counterpart. And they want to do it by 2009. An earlier prototype of the arm, the Proto 1, was shown in April of this year, and now the team of scientists is scrambling to ready the arm's second iteration, the Proto 2, in time to show it off this week at the 25th Darpa Systems and Technology Symposium (where it will likely be joined by Dean Kamen's Darpa funded bionic arm). Researchers hope that the prothesis, which is currently controlled by skin-surface-attached myoelectric sensors, can be made more intuitive by adding injectable sensors, which send increased amounts of signals (and have improved clarity) allowing for greater control of the arm. In time, the team hopes to move to nerve-attached electrodes, or electrode arrays implanted on the brain, which will eventually allow for full user dexterity.

Although the Sensei robot at St. Mary's Hospital in London may just be "one of four in the world," it certainly joins a packed crowd of mechanical colleagues that have been doing this whole "operation" bit for quite some time. As with most similar alternatives, this one operates (quite literally, actually) by responding to a human surgeon's input given via joystick, and the arm is then able to maneuver into more delicate and hard-to-reach locales in order to execute catheter ablation procedures. In the future, however, the Atari-lovin' doctor could be left out of the process entirely, as an automated edition could eventually be programmed to find its own way to the target without any human intervention. Med school graduates losing residency positions to metallic counterparts -- what is the world coming to?

While you'd heard the whispers of a robotic prosthetic arm being crafted by Dean Kamen and his engineering colleagues, very little details have since surfaced on the project. Thankfully, a video was captured during a recent conference in Honolulu, Hawaii where Dean was addressing the FIRST Robotics competition. During the speech, however, he segued (ahem) into a brief glimpse at what's been going on behind the scenes with the device. Shown as "Gen X - Separate Exo Control," the robotic arm was seen demonstrated by team members grasping a water bottle from a friend, picking up an ink pen and turning the wrist over in order to write, and even scratching his nose. Kamen explained that haptic response was paramount, and the "fully completed" prototype sports 14 degrees of freedom (and actuators) and weighs less than nine pounds.

Don't say we didn't warn you, as just days after ASTRO and NextSat successfully completed an autonomous fuel transfer whilst orbiting, the thoughtful duo is already looking forward to the next big challenge. As Scenario 0 operation trials continue, the ASTRO satellite will utilize its "ten-foot-long robotic arm to move objects to NextSat," the first of which will purportedly be a "spare battery transfer" that will be "snatched from ASTRO and plugged into NextSat." Reportedly, this very battery will be the focal point of a number of future handoffs, and a "secondary sensor processing computer" will eventually be offloaded to NextSat as well if the arm cooperates. Of course, these relatively minor exchanges don't mark the end of the work week for these two, as a number of future scenarios look to provide increasingly difficult challenges for "mating" the two machines. Hey, we've already got robotic rights in the works, so we're looking that way for guidance about handling these newfangled (and slightly awkward) mechanical relationships, cool?
