Small-scale soft-bodied robot with multimodal locomotion.

Nature Jan 24, 2018
Untethered small-scale (from several millimetres down to a few micrometres in all dimensions) robots that can non-invasively access confined, enclosed spaces may enable applications in microfactories such as the construction of tissue scaffolds by ro...

Elastic network model of learned maintained contacts to predict protein motion.

PloS one Aug 30, 2017
We present a novel elastic network model, lmcENM, to determine protein motion even for localized functional motions that involve substantial changes in the protein's contact topology. Existing elastic network models assume that the contact topology r...

Robotic vertical jumping agility via series-elastic power modulation.

Science robotics Nov 16, 2016
Several arboreal mammals have the ability to rapidly and repeatedly jump vertical distances of 2 m, starting from rest. We characterize this performance by a metric we call vertical jumping agility. Through basic kinetic relations, we show that this ...
