A reconfigurable soft actuator

Transforming flat elastomers into 3D shapes

06-Feb-2019

Mechanical systems, such as engines and motors, rely on two principal types of motions of stiff components: linear motion, which involves an object moving from one point to another in a straight line; and rotational motion, which involves an object rotating on an axis. Nature has developed far ...

A fast, low-voltage actuator for soft and wearable robotics

23-May-2018

In the world of robotics, soft robots are the new kids on the block. The unique capabilities of these automata are to bend, deform, stretch, twist or squeeze in all the ways that conventional rigid robots cannot. Today, it is easy to envision a world in which humans and robots collaborate -- in ...
