For starters,i have planned to use a soft material such as silicone rubber for actuation.Fabrication of the material seems hard because its done using 3D printing.Is there any other way i could make the actuators without 3D printing ? I have posted the link below to get a clear idea of the soft fish being discussed here.
Thank U @admin ! What is the function of the electronic component in the fish ? Actuation is by soft silicone or plastic then,what other functions do we need the electronic component for ?
