The research objective of this work is to establish and validate a mathematical framework for the inverse design of universal soft robots that:
- Provide exceptional force and power densities.
- Dictate a new means of robotic, automated manufacturing via 3D printed materials exploiting highly anisotropic elastomers, inextensible fibers, and beam elements.
Multiscale inverse design
The actuator geometry's are created to fit specific anatomy given CT scans. VMTK computes anatomy centerlines automatically. Convex blending is implemented to create the robot centerlines of the initial and desired centerlines via a joint angle q. A surface is then fit to the centerlines using Frenet-Serret parametrization.
The current researchers for this project are Mark Gilbertson and Gillian McDonald.
