Its a 100mb video located on a server in Asia, so I was only getting about 15kbps. They were too lazy to put it on youtube . . . sorry!
A team of 13 students from Chulalongkorn University, in the Engineering Innovator Club, made it for a USAR competition. These guys tend to win the competitions in their area, really impressive stuff
I asked them about how they controlled the robot arm . . . they said by dragging a mouse around.
