An apparatus and method for detecting the presence of a slippery material, such as ice, on a surface and for taking action to mitigate the potential hazard presented by such material automatically with little or no human intervention. In accordance with an illustrative embodiment, a mobile machine, such as a robot, is controlled to move automatically across a surface along a path. The mobile machine automatically detects for the presence of a slippery material on the surface as it traverses the surface. The mobile machine automatically takes an action to mitigate the slippery material in response to the detection of the slippery material on the surface.
