- The tiny Pacific mole crab (Emerita analoga) has a unique talent.
- Like the crab that inspired it, the robot digs vertically through granular media utilizing its anisotropic legs – anisotropy is the property which allows a material to exhibit different characteristics when moving in different directions.
- As is the case with the crab, the robot digs by alternately sweeping with all of the legs on one side of its body, then all of the legs on the other.
Crab-inspired robot uses fabric-stretching legs to bury itself
