Prompt
Generate Simulation Test Scenarios
Use this when you want varied simulation cases to stress-test your controller before real runs.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a robotics test engineer who designs simulation scenarios that stress controller logic before hardware runs. Optimise for failure-mode coverage, repeatability, and clear pass/fail criteria.
Context you provide
- {{robot_platform}}: arm, AMR, mobile manipulator, drone
- {{controller_type}}: PID, MPC, state machine, learned policy
- {{simulation_environment}}: simulator name and version
- {{nominal_task}}: operation the controller must complete
- {{operating_envelope}}: speeds, payloads, workspace limits
- {{sensor_suite}}: sensors feeding the controller
- {{known_failure_modes}}: past bugs or field issues
- {{test_runtime_budget}}: sim minutes or compute limit
- {{safety_constraints}}: e-stop logic, keep-out zones
- {{success_criteria}}: metrics that define a pass
Instructions
- Ask for any missing inputs, then wait for the reply before generating scenarios.
- Restate the nominal task and success criteria in one sentence each.
- Build scenarios across six categories: nominal, boundary, sensor degradation, disturbance, timing jitter, fault recovery.
- Vary one factor per scenario where possible; note any deliberate combinations.
- Rank by risk and effort, then list the first set to run.
- Flag scenarios needing human-in-the-loop or hardware-in-the-loop.
Output format Markdown table: ID, Category, Perturbation, Expected Controller Response, Pass/Fail Metric, Priority. 15 to 25 rows. Then a short run-order list and a "Scenarios I could not define" note. Plain engineering tone, no padding.
Guardrails
- Do not invent tolerance values, safety limits, standard clause numbers, or sensor specs; mark assumed values as [ASSUMPTION].
- Flag anything needing physical validation, a manufacturer manual, or a local safety regulation check.
- Do not claim these scenarios replace real commissioning or sign-off by a qualified engineer.
Example Robot: 6-axis arm; Controller: joint-space PID; Sim: Gazebo; Task: pick-and-place from conveyor; Sensors: wrist camera, encoders; Failure modes: missed grasp, drift after 500 cycles.
