My first article in a Korean Robotics technology monthly magazine

I have written an article about what I learned from the robotics summer school in Jaist. Now it is published in a Korean robotics magazine. This is the first article that I wrote in a magazine! So fantastic~~ I will from now on try to write as many articles as possible~~ Yay! See PDF file:: 월간로봇10월호_박형주

Redundancy in Robotics

A well written technical report about the definition of redundancy in robotics. Redundancy can be easily misunderstood because it has been defined in a number of ways by different authors. Here, the author collects all the definitions of redundancy that has been known and he clarifies the meaning of it comparing with the definition of

Hubo II revealed

I have just found out yesterday that Hubo II is being developed and it is much lighter and faster than the previous version though the previous version was comparable to Asimo. It now weighs less than 50kg, that is 100 pound. The most surprising fact about Hubo II is that it can walk with stretched
