Adjustable Buoyancy – Capsule-Based System

To improve the adjustable buoyancy system, we decided on a new design with an old, damaged camera capsule we had on hand. We want to create a piston-like system that allows the volume of air inside the capsule to be adjusted when needed. This principle is similar to a syringe: when the piston retracts, the volume of the capsule increases, increasing buoyancy. Conversely, if the piston were to extend, the overall buoyancy would decrease. This will allow for high-precision, on-demand buoyancy modification. Moreover, we would also be able to explore an automatically adjusting system in the future, where an actuator attached to the piston would compress or extend the piston based on a feedback loop.
