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.

I wanted to work on a new artbot design using Sketchup on my MacBookPro, but immediately ran into a hangup. Sketchup is the third program I've run into that has problems running under the Mac Lion OSX. Thankfully, the Google Sketchup website (link below) lists all the known issue and suggested work-arounds. Hopefully they will be resolved soon. Otherwise I'll have to power up my old WindDoze system, which I really don't want to do just for this one small project.
I've used Google Sketchup in the past to design robot parts and sometimes to create 3D graphics to illustrate articles and manuals. It's extremly handy, easy to use, and the price is right. From time to time I run across other robot builders using it, but I'm not aware of any forum, blog, or website specifically devoted to robot design using Sketchup.
A good example would be the 'Design. Click. Build' Blog that features all types of tips, tricks, and techniques for applying Sketchup for woodworking. If anyone knows, or publishes, a similar website for robotics, please let me know.
The Hasegawa Group located at the Tokyo Institute of technology has been able to integrate artificial intelligence into a semi-humanoid robot enabling it to think, learn, and act by itself. The robot uses a self-replicating neural network to learn in much the same way as its human counterparts. It is able to extrapolate based on its past experience and knowledge combined with observation of its surrounding environment, then make educated guesses. In that sense, it learns from its mistakes, just like a child, and consistently corrects and adjusts until it can successfully perform required tasks.

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.
The BBC recently visited the Cognitive Robotics lab at the University of Ulster, Intelligent Systems Research Center and broadcast a short news segment (see below) covering the advanced robotics research work underway in the lab. While it doesn't disclose anything dramatically new or exciting, the video does provide an additional views of the Willow Garage PR2 preparing coffee and solving a Rubik's cube along with a researching shaking hands with the one of the famous Shadow robotic hands.
That being said, the vintage footage that starts off the video makes it all worthwhile - classic robot camp stuff.
