Researchers at the University of Pennsylvania's GRASP Lab have taught Willow Garage's PR2 robot to identify feces based on color, confront the offending substances, and dispose of them in a state-of-the-art plastic bucket. And judging from this video, UPenn gave GRASP a blank check for their fake excrement budget.
Those plucky quadrotors at UPenn's GRASP laboratory never cease to amaze. In this latest video, watch them autonomously build a structure. In the future, construction workers will be a buzzing, mildly disturbing haze of mechanical diligence.
