Sorry for the delay, but we finally got the video clips from Monday's Onimaru demonstration processed, edited, and uploaded (see video below).
The demo started off with a short exhibition of a humanoid robot built by local college students that Yamaguchi-san has been mentoring and encouraging. Then Onimaru was put through his paces.
They also encouraged some of the children in the crowd to operate both of the robots. For example, the young boy and girl operating Onimaru towards the end of the video are Hikaru and Manaka Fukase. Both are elementary school students and are 9 and 6 years old respectively.
