In planetary geology, a pedestal crater is a crater with its ejecta sitting above the surrounding terrain and thereby forming a raised platform (like a pedestal).They form when an impact crater ejects material which forms an erosion-resistant layer, thus causing the immediate area to erode more slowly than the rest of the region.
Pedestal craters and layers in Tikonravev Crater in Arabia, as seen by Mars Global Surveyor (MGS) with the Mars Orbiter Camera, under the MOC Public Targeting Program. Layers may form from volcanoes, the wind, or by deposition under water. Some researchers believe this crater once held a massive lake.
A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed by the action of wind erosion. At an average height of two to three feet (0.6 to 0.9 m) from the base, the material-carrying capacity of the wind is at its maximum, so abrasion (erosion by wind in which transported materials hit an exposed rock surface ...

The hardened layers are consequently more protected from erosion. This process may occur instead of layers forming under lakes. Some locations on the Red Planet show groups of layered rocks. [24] [25] Rock layers are present under the resistant caps of pedestal craters, on the floors of many large impact craters, and in the area called Arabia.

The Three-Layer Architecture is a hybrid reactive/deliberative robot architecture developed by R. James Firby [1] that consists of three layers: a reactive feedback control mechanism, a reactive plan execution mechanism, and a mechanism for performing time-consuming deliberative computations.
