A robotic system which includes a fluid controller, an arm portion, and a soft end effector apparatus coupled with the fluid controller and the arm portion. The soft end effector apparatus includes a base constructed and arranged to mount to the arm portion, a set of wrist assemblies coupled with the base, and a set of finger assemblies coupled with the set of wrist assemblies. Each wrist assembly of the set of wrist assemblies (i) couples with a respective finger assembly and (ii) provides movement to that respective finger assembly relative to the base during actuation of that wrist assembly and during independent actuation of that respective finger assembly in response to control from the fluid controller. Along these lines, the fluid controller may individually provide pressurized fluid to each wrist assembly and each finger assembly when controlling interaction between the soft end effector apparatus and an external object.

A variable buoyancy device has an inner region and an outer cavity. The outer cavity extends at least partially around the inner region and is adapted to contain fluids, such as a liquid and a gas, the relative proportions of which can be varied to vary buoyancy. The inner region provides an advantageous location for equipment, while the outer cavity provides a significant volume for achieving a wide range of buoyancy adjustments.

Changing buoyancy based on combining a liquid with a substrate
A technique for varying buoyancy of an apparatus includes providing a substrate configured to produce gas on demand when exposed to a liquid, exposing the substrate to such liquid, and capturing the gas produced by the substrate to increase the buoyancy of the apparatus within a fluid. In some examples, the liquid and the fluid contain the same material, such that gas may be produced using fluid already in the environment.
