PenSSCys
PenSSCys (Penetrating Subsurface Cyber Systems) is a fictional class of autonomous, modular devices designed to operate in challenging subsurface environments. In speculative engineering literature, PenSSCys units are described as compact, long-lived, and able to collect environmental data while maintaining a low detectability profile.
Each PenSSCys consists of a sensor payload suitable for chemical, seismic, thermal, and electromagnetic measurements, a
PenSSCys units are envisioned to perform subterranean reconnaissance, structural health monitoring of tunnels and mines, post-disaster
The term originated in speculative design discussions and has appeared in science fiction and thought-experiment papers
Autonomous robots, Cyber-physical systems, Subterranean robotics.
Note that PenSSCys is fictional; no official specifications or deployments exist.
