Some people buy a humanoid robot kit, do the assembly, play around with it for a few days, then it gets put on the shelf. Others, like DirtyRoboto, see it as a challenge and long term learning experience. They realize that the initial assembly is only the beginning of the journey.
DirtyRoboto, his nickname on the Robosavvy Robot Forums, seems to be making real progress, and enjoying every minute of it. A few weeks ago he added some custom designed grippers to "Takeshi", his Robonova-1 humanoid robot, and now he apparently wants his robot to become a major league baseball pitcher!
