Inspired by Festo's Aquajelly, I'm building a robot that will move in a similar way with a limited number of resources. I started this project a year ago in Fall of 2013 and am finally picking it back up again with the intention of finishing it (maybe even making a water safe version too!)
This weekend I started printing the newly redesigned pieces for my jellyfish robot. I got about 90% finished by Sunday, but not enough was intact to start testing out whether or not the design will move like it should.
About a year ago I started building a robotic jellyfish inspired by Festo's submergible AquaJelly. I was just beginning to figure out how to get the thing moving when I got sidetracked with the prospect of launching a Kickstarter campaign and dropped the project cold. During this whole long year while I've been fulfilling the said Kickstarter, this poor jelly prototype ("Boney") has watched silently from a distant shelf in the workroom, begging me to pick it up again. Finally this weekend I was able to spend some time giving the old parts a makeover… in yellow.
I added a nice gentle curve to the moving pieces, taking after the design of its cousins, the delta robots :
