Highlights

  • A novel software workflow for exploration of the complex design space of pneumatic soft actuators

  • Prioritization of seamless connectivity between design and evaluation phases: geometry and material specification, visualization, simulation, and fabrication 

  • A graphical user interface for interactive exploration of computational network representations of implicit geometry functions

  • Automated generation of simulation input files for one-click execution of nonlinear FEA evaluation of candidate designs

A Seamless Workflow

  • Multimaterial soft actuators at progressive stages of development in our workflow. From left: signed distance function geometry description; surface triangulation and material assignment; simulated deformation during actuation; preparation for additive manufacturing; 3D-printed actuator.

An Interactive Design Tool

  • Our GUI-based, interactive design tool lowers barriers to multimaterial soft actuator design

  • Automatic generation of FEA studies using shell and volumetric elements. Shell element offer drastically reduced computation cost at the expense of lower resolution and accuracy.

Fabricated Actuators

  • Actuators designed in our workflow can be fabricated by additive manufacturing and actuated using pressurized fluid.
