cameras, so a virtual representation of the scene. the first look we have gotten, by the way, this last sunday, the first look inside of the fukushima plant comes via the i-robot packbottoms. and i know we have seen your roomba vacuum. is that sort of the same science between this packbot concept? i-rebottom is a spin-out of m.i.t., a 20-year-old company. we laugh about it being the world s overnight success. but the autonomy, the integration of electro mechanical capability is very similar. but very advanced in our military robots, and very cost effective in our consumer robots that serve in the home. and you mentioned also that these were these have been used for a while now in afghanistan and iraq. so these are the same robots that would, what, detect bombs and dispose of bombs?
