A good answer to Maintaining Companion Robots: Three Rules for Troubleshooting, Privacy and Replacement should still make sense after the novelty wears off. The approach here is to start with repeatable household outcomes, then test the product or setup against constraints, recovery and long-term support before giving convenience extra weight.

Rule 1: diagnose by layer

Separate physical, power, navigation, network, account and AI-service problems. A robot that cannot leave the dock may have a physical obstruction or battery issue; a robot that moves but cannot call may have network or account trouble; a fluent but wrong answer is an information-quality problem. Layered diagnosis prevents unnecessary factory resets.

Rule 2: treat privacy settings as maintained configuration

After updates, new integrations or household changes, recheck camera, microphone, history, remote-view and diagnostic settings. Privacy can drift even when nothing 'breaks.' Maintain a room-and-sensor map so the household can tell whether the current setup still matches the original purpose.

Rule 3: replacement is about support and role fit, not age alone

There is no universal retirement age for a companion robot. Replacement becomes reasonable when security/support ends, batteries or critical parts are unavailable, navigation can no longer cope with the home, recurring failures consume too much labor, or the household’s role for the robot has changed beyond what the device can safely support.

Evidence: keep a short incident log

For each meaningful fault, record date, room, battery/charging state, network state, software version if available, symptom and recovery. Include privacy surprises and unwanted autonomous actions, not only mechanical faults. Patterns become visible only when events are comparable.

Exception: do not troubleshoot safety-critical damage indefinitely

Swollen batteries, overheating, damaged charging equipment, exposed wiring, repeated collisions or a relevant recall are reasons to stop and follow official guidance rather than keep experimenting. Use the manufacturer and current CPSC information for the exact model where applicable.

Boundary: AI behavior needs monitoring, not 'calibration by belief'

When conversational behavior degrades or changes after updates, document examples and reduce authority if necessary. Do not compensate for unreliable high-consequence answers by simply prompting more aggressively. The safe response may be to narrow the robot’s role and route important questions to a person or authoritative source.

Working decision notebook

Physical Layer

Review physical layer from the perspective of someone managing rooms, docking, updates and support life. Follow the process from the user’s first action through recovery, including any hidden work created by rooms, docking, updates and support life. Record the symptom before changing settings so the maintenance history remains useful. If the answer depends on a vendor service, record the date and the exact support assumption that makes it true.

Power Layer

For power layer, anchor the check in a home with cameras, microphones, movement and cloud services. Separate what the manual promises from what the household actually sees, especially where privacy, navigation, account roles and human fallback can change the result. Record the symptom before changing settings so the maintenance history remains useful. Define a stop point so repeated trial and error does not turn a routine issue into a larger safety, privacy or access problem.

Navigation Layer

Treat navigation layer as an operating question inside privacy, navigation, account roles and human fallback. Observe one normal use, then one ordinary failure; note which part of rooms, docking, updates and support life becomes harder and who has to intervene. Record the symptom before changing settings so the maintenance history remains useful. Keep the result with the model or setup notes so a future review of companion robots starts from evidence rather than memory.

Network Layer

Put network layer on paper before changing anything in daily companionship without granting unsafe authority. Ask another household member to repeat the task without coaching and record where privacy, navigation, account roles and human fallback introduces hesitation, work or ambiguity. Record the symptom before changing settings so the maintenance history remains useful. If the test cannot be repeated, the conclusion is too fragile to support a long-term companion robots decision.

Account Layer

Use account layer to challenge the comfortable assumption around rooms, docking, updates and support life. Write down the expected behavior, reproduce it once, and then remove one convenience so the dependency on rooms, docking, updates and support life becomes visible. Record the symptom before changing settings so the maintenance history remains useful. A passing result should be explainable in plain language by somebody who did not configure the system.

Second-pass stress test

Physical Layer: retest

Put physical layer on paper before changing anything in rooms, docking, updates and support life. Follow the process from the user’s first action through recovery, including any hidden work created by rooms, docking, updates and support life. Record the symptom before changing settings so the maintenance history remains useful. If the answer depends on a vendor service, record the date and the exact support assumption that makes it true. Recheck the same point after a small household change; the difference between the two observations is often more informative than either snapshot alone.

Questions before committing

What should be checked weekly?

Dock access, visible physical damage, charging behavior and any repeated navigation exception.

What should be checked after an update?

Privacy/sensing state, integrations, account behavior and any changed autonomous action.

When should the robot be powered down?

When official guidance, recall information or visible damage indicates continued use may be unsafe.

How do you distinguish network from AI failure?

Confirm connectivity and account state first; if those work but content is wrong, treat it as an information-quality issue.

What is a replacement trigger?

Unsupported security, unavailable critical parts, repeated unrecoverable faults or loss of role fit.

Boundary note

For Maintaining Companion Robots: Three Rules for Troubleshooting, Privacy and Replacement, this is consumer technology guidance, not medical, caregiving, emergency-response, legal or privacy advice and not an AI/product certification. Do not make a companion robot the sole path for high-consequence care or emergency help unless the exact service is designed and supported for that role. Review the provider’s current privacy, security, update and support terms; this 维护排错 keeps an independent human fallback as a hard boundary.
