Hasta La Gadget!

We’ve known little of the genetic sequences of our precursors, despite having found many examples of their remains: the requirement for two strands in traditional DNA sequencing isn’t much help when we’re usually thankful to get just one. The Max Planck Institute has devised a new, single-strand technique that may very well fill in the complete picture. Binding specific molecules to a strand, so enzymes can copy the sequence, has let researchers make at least one pass over 99.9 percent of the genome of a Siberian girl from roughly 80,000 years ago — giving science the most complete genetic picture of any human ancestor to date, all from the one bone you see above. The gene map tells us that the brown-skinned, brown-eyed, brown-haired girl was part of a splinter population known as the Denisovans that sat in between Neanderthals and ourselves, having forked the family tree hundreds of thousands of years before today. It also shows that there’s a small trace of Denisovans and their Neanderthal roots in modern East Asia, which we would never have known just by staring at fossils. Future discoveries could take years to leave an impact, but MPI may have just opened the floodgates of knowledge for our collective history.

If you’ve ever wanted your own little humanoid robot to do your bidding, there’s a new kid in town you might want to check out. It’s called the HOVIS Eco, and it comes from Korea’s Dongbu Robot company.

The medium-sized humanoid Eco robot measures about 16.4″ tall by about 7.6″ wide, weighs just under 4 pounds, and has 20 degrees of freedom thanks to a large number of servo actuators. Unlike some humanoid robots, Eco has a friendly, modern look about it that’s not freaky or intimidating in any way. In fact, the little robot looks like it would be at home in a science-fiction movie that doesn’t involve a dystopian future.

Under its hard and shiny shell, Eco is powered by an Atmega 128 controller, which can be programmed using using bundled graphical editing software, or via a variety of APIs, using C++, Java, Python or the Android SDK. It can also be controlled by wireless remote. It comes with distance and sound sensors, and can be upgraded with an optional gyro sensor as well. The robot even comes packaged in a handy tool case making it easy to maintain and store.

While I can’t find a video of the Hovis Eco in action, here’s some footage of the Hovis Lite, the Eco older, uglier brother pulling off some impressive moves:

Priced at $900 (USD), the Hovis Eco is no toy, but it’s a serious hobbyists robot. If you’re interested in getting your hands on one, you can find it over at RoadNarrows Robotics.

Robots can clean your pool and pick up after your lavish dinner parties, but what use is Mr. Nao when you’re ringing for a nightcap from the comfort of your second-floor bedroom? Okay, so we’ve seen the odd bot take a journey up some stairs, but how many cyborgs are prepared to scale flights that twist and turn? Researchers from the University of Freiburg’s Humanoid Robots Laboratory have demonstrated a Nao humanoid capable of climbing spiral staircases, which, of course, are more challenging to scale than their non-curving counterparts. A laser range scanner on the top of the robot’s head provides a global estimation of the bot’s position, and the humanoid uses a 3D model of the staircase to match up with the images it captures on each step. This system lets it get a good enough grip on its geography to successfully detect stair edges and make it to the top with nary a trip. Take a look for yourself in the video below.

For the first time, scientists have managed to use fMRI scans of a human to control the movements of a robot body. The link between man and machine allowed the researchers to control a robot in France from a brain scanner in Israel. More »
