A Force-Position Control System Based on Soft Tissue under Large Deformation

A Force-Position Control System Based on Soft Tissue under Large Deformation

We introduce an extension of the mass-spring model applied to human tissue that can truly reflect the mechanical properties of a living person's tissue under large deformations under pressure by a massage head. The model is used in the force-position control system and helps us to control the m...
