Configurational forces explain echelon cracks in soft materials
Angel Santarossa, Nydia Roxana Varela-Rosales, Paul Steinmann +1
Soft fracture in highly deformable solids involves both geometric and constitutive nonlinearities, necessitating advanced theoretical and computational frameworks for its accurate…
Enhanced Interlocking in Granular Jamming Grippers through Hard and Soft Particle Mixtures
Angel Santarossa, Thorsten Pöschel
We investigate the influence of particle stiffness on the grasping performance of granular grippers, a class of soft robotic effectors that utilize granular jamming for object mani…
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…
Granular binary mixtures improve energy dissipation efficiency of granular dampers
Nydia Roxana Varela-Rosales, Angel Santarossa, Michael Engel +1
Granular dampers are systems used to attenuate undesired vibrations produced by mechanical devices. They consist of cavities filled by granular particles. In this work, we consider…
Effect of Particle Size on the Suction Mechanism in Granular Grippers
Angel Santarossa, Olfa D'Angelo, Achim Sack +1
Granular grippers are highly adaptable end-effectors that exploit the reversible jamming transition of granular materials to hold and manipulate objects. Their holding force comes…
Soft particles reinforce robotic grippers: Robotic grippers based on granular jamming of soft particles
Holger Götz, Angel Santarossa, Achim Sack +2
Granular jamming has been identified as a fundamental mechanism for the operation of robotic grippers. In this work, we show, that soft particles like expanded polystyrene beads le…
Effect of the granular material on the maximum holding force of a granular gripper
Julián M. Gómez--Paccapelo, Angel A. Santarossa, H. Daniel Bustos +1
A granular gripper is a device used to hold objects by taking advantage of the phenomenon of Reynold's dilatancy. A membrane containing a granular sample is allowed to deform aroun…
