We've designed and printed molds for the actuating section of a pneumatic fish, pictured below. These are: the outer shell mould (white, center), the cavity mould (purple, left), and the restrictive interface mould (Purple, right).
in addition to the cavity mould shown above, we printed another, mirror image mold to compliment the existing half and for a full tail. The pneumatic actuators cast from these moulds, or "fish fillets" as we call them, are both done, and currently curing to the interface. Hopefully, we will be able to observe their functionality later tonight.
Today, we received some components crucial to the progress of our project. This includes such items as 1/16" ID tubing, and m5 sub-plates and connectors for our valves (pictured below).
Over the next couple days, we intend to determine a configuration of electronics that fits inside the fish form factor and provides adequate functionality. We will do this by experimenting with the current tail, interfacing through a connector plate (yellow, top in first picture) until a more permanent container can be designed.
