Translation of a spherical object. Translation of a spherical object. The soft ring oscillator rolls a ball on an elastomeric track. The track relies on sequential inflation of serially arranged elastomeric chambers to translate objects (A). A circular track can roll a ball indefinitely; the schematic illustrates a completely soft design of a circular track with 30 internal chambers (B), which we used in an experimental demonstration shown here (C) and in movie S3.
