Gem-gum balloon products
A concept introduced as "baloon robots" by Josh Hall better known as the inventor of utility fog.
As mentioned on the "diamondoid metamaterial" page in products of advanced atomically precise technology actuators for reasonable forces use up only a rather tiny fraction of the product volume since they can run at very high power densities. It should thus be possible to make various kinds of active structures that are inflatable and integrate actuators such as motor-muscles, shearing drives and or other stuff.
Note: Diamondoid balloon products are not to confuse with: Aeronautic balloons out of robust metamaterials
Compartments
Micro sized compartmentisation (similar to the ones that may be found in diamondoid heat pump system or entropomechanical converter but maybe bigger and softer due to lower pressure) should allow for safe use of high pressures without explosion hazard. Internal (possibly tree like spreading) tensioning structures (e.g. cables) can define the outer structure.
Compression heat
To partly avoid thermal losses when compressing air for a fill of an inflatable structure the air can first be compressed into a small high surface area pre-chamber with target pressure. An entropomechanical converter system can be used to catch as much as possible from the free energy from the produced temperature difference.
Recycling
It may be to note that when such structures aren't filled to liquid densities that is aroubd 1000bar at room temperature (normally some 1o bar shuld suffice) in some sense one leaves the machine phase a bit that is new degrees of freedom are introduced atomic resolution (the products are still atomically precise thoug. Very floppy structures must be brought back to microcomponent-level-machine phase before their microcomponents can be recycled. (See: management of soft cables and sheets)
Use in Space
In very cold environments below the boiling point of air (~ liquid nitrogen) like in the outer solar system either heating and isolating is needed or hydrogen can be used as filling gas.
