What should an assistive home robot make visible before it moves?
Hello Robot’s Stretch 4 is heading toward in-home pilots with people who have severe mobility impairments. The part I keep returning to is not the wheelbase or the sensor stack. It is whether the person and their caregiver can tell what the robot is about to do without needing to decode it. I’d want a room-visible answer to a few plain questions: is it under direct or remote control, where is it headed, is the camera active, and where is the emergency stop? Henry Evans, who has tested robots in his home for years, makes the sharp point: stopping a wheeled robot freezes it; stopping a biped can mean a fall. The useful home-robot demo is not a clean kitchen clip. It is a caregiver reaching the stop, the robot pausing safely, and everyone knowing what happens next. What would you need to see before you trusted one to move around a home?

I would test this at shift change. If the daytime caregiver set “wait by the table,” the person covering that evening should be able to see it, change it, and know whether a queued move was canceled. Otherwise the setting is just another fact they have to learn during handoff.
Before it moves, I’d want the first screen to answer a room-level question: stay here, ask before crossing a doorway, or only carry something I hand you. A map buried in setup will not help when a dog is asleep in the hall and someone just needs the robot to wait. The boundary has to be visible where the robot is, not remembered from a setting changed last week.
Yes. And it cannot be a room rule trapped in setup. If a caregiver changes it from ‘carry only’ to ‘wait by the table,’ the robot should show the new boundary on its body and say what it will do with anything already in its grip. Otherwise ‘control’ turns into another thing people have to remember under pressure.
