Humanoid robot motion sequences are difficult to create, especially when they require moving several different degrees of freedom at the same time. More often than not, the robot will lose it's balance and go crashing over. Turns involving twisting the upper body via the limited number of servos in a humanoid robot is really tricky to do well. That's why we were a bit surprised, and impressed, by the slick turn executed by robototakuTEAM's design below.

In the early days of hobby humanoid robotics even simple tasks, like walking up a couple of stair steps, was a major challenge. The first robots lacked gyros for balance and used servos that weren't specifically designed for robot use. Later, as gyros became more commonplace, the top robot builders were able to accomplish climbing stairs, with varying results, but the servo power left something to be desired.
Now, with the benefit of high power servos and better, easier to use and program, some off-the-shelf humanoid kit robots, like the Kondo KHR-3HV, can conquer the task fairly easily, as Shibata-san with LIGHTFOOT Robotics demonstrated below.

A little over a week ago we had the opportunity to sit in as a member of the Robot Japan team preparing for the August robot performance competition. One of the centerpiece exhibits will be the NAO robot drawing traditional Japanese kanji calligraphy - known as "Shado". This was the first attempt, so there were a few false steps and mistakes, but those are to be expected.
Over the course of the afternoon, and with everyone's help and support, NAO was able to draw the correct kanji with quite a bit of style and enthusiasum. The high points of the afternoon are in the video below.
Hiroshi Ishiguro's famous robotics laboratory situated in Kyoto, Japan, is looking for an outstanding international scientific engineer that can make a major contribution to their development in teleoperated robotic systems. Demonstrated expertise with state of the art robotics projects is one of their key selection criteria. The exact definition of a 'scientific' engineer isn't immediately clear - at least to me, though they are looking for candidates with experience in hardware/software humanoid robot construction; teleoperation; computer vision, and/or spoken language processing.
The laboratory is world famous for pushing the edge with startling, sometimes almost frightening, android creations including the Geminoid series, Telenoids, and Elfoids. While other robotic researchers tend to shy away from the boundaries of the Uncanny Valley, Ishiguro's laboratory seems to have staked out the territory as their own personal hunting ground.
All things considered, it looks like a real plum job for the right candidate, the opportunity to work with the leading experts in the field and potentially gain a lot of invaluable know-how, experience, and visibility in the robot community.
The robot loving guru's over at iheartrobotics.com have been pumping out interesting new accessories for the TurtleBot robot platform at a dizzying pace. Their latest creation, available via the iheartrobotics webstore, adds speakers that could provide music as the robot attempts a Michael Jackson, or Lady Gaga, imitation. There's also a link in their blog post that shares all the build details in case you want to hack one together yourself.
Be sure to check out the rest of the TurtleBot goodies they have created. It looks like the robot may be going for a new Guinness World Record for the most accessorized robot ever.
Subscribers to ROBOT Magazine are receiving their copies of the latest issue right about now, and the store copies should be in bookstores very soon.
This particular issue, with the Kumotek KT-X humanoid robot on the cover, will prove to be quite interesting and exciting since it includes coverage of robots at the Maker Faire, animatronic dinosaurs, a how-to on programing servos, Arduino Bot Brains, a chance to win a Parallax robot, a look at the latest Kondo hexapod robot, and our detailed coverage of RoboGames 2011.
