Objectives for this week
- Update the tentacle shape to prevent inflating and cause bending.
- Create new mold, and fabricate the new jellyfish
- Test the new jellyfish in the tank
- Stretch goal: test with pneumatic system
Summary of Week Results
We created a new jellyfish tentacle design that had smaller cavities and air channel so that when air flows, it pushes the top of the tentacle outward so that the overall tentacle bows. The jellyfish will be formed from a top piece with all the cavities/complicated geometry and a bottom thin and flat flap.
What worked well: using fabric to make the bottom flap stiffer, the 2 part mold for the top and the flap for the bottom, was able to get noticeable curvature change in each tentacle
What can be improved: middle ring should have thicker walls, attachment of tube to mold should be stronger
Objectives for next week
- Create a new jellyfish that uses the hydraulic pump
- Wire and test it in the fish tank
