Abstract:

Heterogeneous legged robot fleets combine platforms that differ in body length, payload, locomotion mode, and sensor mounting, and these differences normally force each embodiment onto its own local planner. This fragmentation duplicates code, complicates validation, and allows planning behavior to drift between robots that share a mission. This paper extends the configuration-driven planning idea of AgniNav from a single robot to the fleet level. The proposed abstraction has three parts: a compact, typed configuration schema that separates collision geometry, kinematic and payload limits, locomotion class, and sensor rig; a configuration registry service that validates descriptors, issues content-addressed handles, and caches derived planning quantities; and a planner interface that accepts configuration handles instead of compiled-in robot parameters. One bit-identical planning binary was evaluated on a simulated fleet of four morphologies, namely Go2-class and B2-class quadrupeds, a 1.4 m humanoid, and a four-wheel-drive rover, each with a distinct sensor rig, across 15 mixed-fleet scenarios with 5 seeds each. Compared with four separate per-embodiment code paths, the shared planner raised shared module reuse from 83.2 to 87.2 percent, lowered configuration load latency from 1.9 to 1.8 ms and 95th-percentile replanning latency from 38 to 34 ms, and raised plan quality parity from 81.2 to 96.4 percent, whereas a shared planner driven by ad hoc configuration flags reached 88.2 percent. Ablations attribute the largest share of the gain to the sensor-rig abstraction. The remaining failures involve differential-drive behavior on steep slopes and registry cold starts under concurrent load.
