Personally, I haven't seen one of these yet in real life but autonomous robot delivery, last month, were legalized in Pennsylvania. They have also been classified as pedestrians.
Apparently these babies can go up to 12mph on the sidewalk, so watch where you're walking! When not on the sidewalk or in pedestrian areas, they can go up to 25mph. Autonomous delivery robots were being tested a while ago at Pitt but were pulled for a little while after experiencing some hiccups.
