A family of mem-models, including the mem-dashpots, mem-springs, and most recently, mem-inerters, is emerging as a new powerful way capturing complex nonlinear behaviors materials systems under various types dynamic loads involving different frequency, amplitude, loading histories (e.g., hysteresis). Under framework state-space representation hybrid dynamical systems, mem-springs may be formula...

This paper describes a system in which multiple robots cooperate to move multiple objects such as groups of boxes using a constrained prehensile manipulation mode, by wrapping ropes around them. The system consists of three manipulation skills: tieing ropes around objects, affecting rotations using a flossing manipulation gait, and affecting translations using a ratcheting manipulation gait. We...
