Walk around the activity area
Look at both floor level and arm height. Small toys, table corners and charging cables can be missed if you inspect only through the camera view.
Consider people and pets
Choose an area with little foot traffic, keep pets out of the movement zone and leave room for supervision. Review the space whenever its arrangement changes.
A checklist supports observation
Completing every item does not mean every activity is suitable. Review the particular activity's instructions and stop if the conditions do not support it.
