Nanomachines, son

Metal Gear RAY had a more organic design than previous models, both in appearance and in function. Its streamlined shape helped to deflect enemy fire and allowed for greater maneuverability both on land and in water. Its interior workings were also somewhat organic, as it had artificial fibers that contracted when electricity was applied, much like natural muscle, instead of typical hydraulics; this pseudo-muscle tissue made it very maneuverable. It also had a nervous-system-like network of conductive nanotubes, which connected the widely dispersed sensor systems and relay commands from the cockpit to the various parts of RAY's body, automatically bypassing damaged systems and rerouting to auxiliary systems when needed. Another feature was its blood-like armor-repair nanopaste, which was secreted from valves and coagulates wherever the exterior surface was damaged.
