It has been recently reported that irregular objects sink irregularly when
released in a granular medium: a subtle lack of symmetry in the density or
shape of a macroscopic object may produce a large tilting and deviation from
the vertical path when released from the free surface of a granular bed. This
can be inconvenient -- even catastrophic -- in scenarios ranging from buildings
to space rovers. Here, we take advantage of the high sensitivity of granular
intruders to shape asymmetry: we introduce a granular intruder equipped with an
inflatable bladder that protrudes from the intruder's surface as an autonomous
response to an unwanted tilting. So, the intruder's symmetry is only slightly
manipulated, resulting in the rectification of the undesired tilting. Our smart
intruder is even able to rectify its settling path when perturbed by an
external element, like a vertical wall. The general concept introduced here can
be potentially expanded to real-life scenarios, such as ``smart foundations''
to mitigate the inclination of constructions on a partially fluidized soil.
