Muratagirl, the unicycling robot, is back at Japan’s Ceatec with improvements and some new tricks. The updated robot is used to promote science and technology to Japanese children. Muratagirl can go around a curve with a diameter of 75 centimeters and ride over a balance beam just two centimeters wide. The 2009 model can also cycle at 15 centimeters per second; triple the speed of the 2008 model.
