Discrete-time multi-robot instability detection simulation

A simulation demonstrates early detection of cascading failures in a network of six robots arranged in a ring topology. When robot R2's efficiency suddenly drops to 0.3 at timestep 120, the remaining robots must absorb the redistributed workload, creating a cascade toward system overload. The detection system successfully identifies this instability by tracking variance patterns in robot loads and using statistical trend analysis to predict failure before any robot exceeds the critical overload threshold of 150.0.
