Kari Love (@ikyotochan) spoke with us about creating soft robotics. You can see her edible soft robots talk from 33c3. Kari works at Super-Releaser. Her personal site (and blog) is Kari Makes.
Kari mentioned that the Super-Release intern Aidan had some picks for soft robotics on Instructables.
Super-Releaser created the Glaucus soft robot and Adafruit has an in-depth tutorial for how to make it.
Some videos of soft actuators and soft robots:
Soft Exoskeletons
Rat heart cell robot from Popular Mechanics
First Autonomous Entirely Soft Robot (Harvard Octobot)
VoxCad Tutorial for simulating soft robotics
Also, if you haven’t seen Big Hero 6, you should. Consider it computer science homework. If you just want to see Baymax, here is a short video.
