I would agree with you if the author wrote, "I don't count as home robots small four legged robots as they don't navigate around clutter, they just go over it" but the author didn't write that.

The author quoted two constraints (safe around children, must include a form factor able to preform an action) not specified.

The author projected that a lab demo of capabilities would not occur. I don't see safety for children as necessary for a lab demo.
