Summary

Peg-in-Bench makes insertion evaluation reconfigurable with printable geometries, tolerances and machine-readable scenarios.

Modular pegs and bases can vary layouts, orientations and task structures while holding other physical conditions controlled. A scenario tool emits standardized configurations and descriptions, and the authors released the STL files and repository. The contribution is an evaluation apparatus, not a new insertion policy.

Why it matters
