- Map model, robot, operator, and site responsibilities
- Give the recommendation before the framework.

Design the deployment control plane for rolling a new policy to a heterogeneous robot fleet.
Build a defensible answer, then pressure-test it in the same workspace where you can save the attempt.

Start with a position
Give the interviewer your decision before the framework.
For “Design the deployment control plane for rolling a new policy to a heterogeneous robot fleet.” at Physical Intelligence, my recommendation is a staged deployment loop with task-level telemetry, safe fallback, replay, and targeted data collection. I would define the user-visible contract first, then compare architecture and model choices through task quality, reliability, latency, cost, and recovery—not technical elegance alone.
Preview the reasoning
Three moves to make the answer concrete.
Map the system
- Define safe fallback and intervention
- Compare at least one credible alternative.
Choose the boundary
- Close the loop from deployment failures to data and training
- Compare at least one credible alternative.
Measurement check
A metric is useful only when it changes the decision.
- North star
- task progress without unplanned interventionMeasures the repeated user or customer outcome, not mere feature activity.
- Diagnostic
- generalization and recovery successExplains whether quality and the critical journey improved for the intended segment.
- Guardrail
- failure severity, intervention time, and data-to-fix cycleMakes the principal downside observable: a rare physical failure that the offline benchmark, rollout gate, or monitoring system cannot detect.
Interviewer pressure test
Do not stop when the first answer sounds polished.
- Why prioritize an operator or researcher responsible for safe, repeatable robot performance outside the lab, and who did you explicitly defer?
- How would your answer change with two weeks, three engineers, or a tenfold scale increase?
- What is the strongest rejected alternative and when would it win?
