Researchers propose ROSA, a robotics foundation model serving system designed for robot factories that moves beyond single-robot, edge-computing assumptions. The system utilizes shared GPU-pool serving to allow fleets of robots to access server-class GPUs over the network.

  • ROSA adopts shared GPU-pool serving to improve inference performance, battery duration, and GPU utilization across a fleet.
  • It provides a robotics-aware programming abstraction supporting multi-model pipelines, per-task performance requirements, and failure handling.
  • The system uses factory-objective-driven scheduling to maximize SLO-qualified factory productivity rather than minimizing individual request latency.
  • Implemented on Ray Serve with vLLM, PyTorch, and JAX backends, ROSA improves factory productivity by up to 12.06x over conventional dedicated serving systems.

ROSA addresses the limitations of existing systems by optimizing for collective factory outcomes instead of isolated robot latency.
