Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Control of Actuators with Linearized Variable Stiffness
IFAC-PapersOnLine, 2019 Abstract In this paper, a new model of variable stiffness actuators (VSA) is presented. In the proposed model, the stiffness and deformation of the elastic element can be controlled independently. The structure of the model allows the use of optimal control methods, such as linear quadratic regulator, as is demonstrated in the paper. The model can be
