Robotic Installation (Industrial Manipulator, Humanoid Agent),
Real-time Simulation, Orbital Debris Data

Stardust Yu Gong critiques the "innovation delusion" of constant novelty. By binding technical capacity to inheritable obligation, it asks: How do we design systems that survive political cycles and technological obsolescence? The work transforms the robot from a machine of simple labor into a vessel for intergenerational care, arguing that to survive the deep future, we must design for lineage rather than ownership.

Concept: The Steward Regime

Stardust Yu Gong is a robotic art installation that reimagines our relationship with deep-time hazards, specifically the accumulation of orbital debris. It proposes a shift away from traditional robotic roles—the obedient Slave, the detached Judge, or the charming Butler—toward a new modality: the Steward.

The work draws its title and philosophical core from the Chinese fable of Yu Gong (The Foolish Old Man). Unlike the myth of Sisyphus, who is condemned to futile, repetitive labor that resets every day, Yu Gong attempts to move a mountain with the knowledge that the task exceeds his lifespan. His solution is lineage: the obligation is passed down, ensuring that while the mountain is finite, the effort to remove it is infinite and cumulative.

The Installation: Suspended Labor

Visually, the work presents a "kinetic umbilical." A massive industrial robotic arm acts as an infrastructure layer, suspending a life-size humanoid robot in mid-air.

Using active admittance control, the industrial arm provides buoyancy-like support, canceling gravity to simulate the physics of an extravehicular spacewalk. The humanoid is not a puppet but an agent; it floats in a microgravity drift, oriented not toward the audience, but toward a projection of the "invisual" hazard of space debris.


The System: A Rolling Risk Corridor

The environment is not a pre-rendered loop. It is a live simulation driven by the Continuity Criterion.
  • Real Data: The system ingests Two-Line Element (TLE) sets from CelesTrak archives, creating a scientifically grounded representation of current orbital pollution.
  • The Corridor: Instead of trying to visualize all debris at once, the system calculates a "Rolling Risk Corridor"—a time-windowed set of high-probability collision risks that the robot must address.
  • Sedimentation: When the humanoid acts to "clear" a path, the system does not simply play an animation. It records the intervention, the energy expended (motor torque), and the risk reduction.

The Anti-Reset Logic

The defining feature of Stardust Yu Gong is that it refuses to reset.

In a standard video game or art installation, restarting the system wipes the slate clean. Here, the system implements sedimentation. Every intervention made during the exhibition is written into a permanent "world-state." When the system reboots or a new operator takes over, the installation "rehydrates" the previous state. The new session inherits the progress, the wear-and-tear, and the data of the previous generation.
