Reciprocal swimming in viscoelastic granular hydrogels
Hongyi Xiao, Jing Wang, Achim Sack +2
We experimentally study a scallop-like swimmer with reciprocally flapping wings in a nearly frictionless, cohesive granular medium consisting of hydrogel spheres. Significant locom…

Locomotion of a Scallop-Inspired Swimmer in Granular Matter
Hongyi Xiao, Harol Torres, Achim Sack +1
Understanding swimming in soft yielding media is challenging due to their complex deformation response to the swimmer's motion. We experimentally show that a scallop-inspired swimm…

Granular jamming gripper with integrated suction
Angel Santarossa, Olfa D'Angelo, Achim Sack +1
Granular grippers can manipulate a wide variety of objects, but need to be pressed on the object to conform to it. If the object is placed on unstable ground, e.g., on sand or wate…
