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:

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.
