Passive Vibration-Driven Locomotion
Anna Zigelman, Gilad Israel, Yizhar Or +1
We investigate a concept of passive, vibration-driven locomotion, in which a mechanical system achieves horizontal self-propulsion by resonantly harvesting energy from vertical env…

Dynamics and multi-stability of a rotor-actuated Twistcar robot with passive steering joint
Anna Zigelman, Zitao Yu, Rom Levy +1
The nonlinear dynamics of many under-actuated wheeled platforms are governed by nonholonomic constraints of no-skid for passively rolling wheels, coupled with momentum balance. In…

Magnetic control of metafluids for fluid-like applications of metamaterials
Ezra Ben-Abu, Anna Zigelman, Sefi Givli +1
Metamaterials are structures composed of repeating unit-cells which enable macro-scale properties not found in nature. Since metamaterials are typically solid structures with prede…
