I was just casually going back home from college, GMU, AND I saw a little starship food delivery robot taking a quite peculiar route so I stop by to see what It does with a blocked path. After coming back, it got stuck on mug and couldn't move anymore. And IT ASKED FOR HELP!!! It said" can you help me back on the road ?" Quite politely. After helping it, he stopped and TALKED AGAIN: this time say HI and asked me to take a picture with me!!! After the picture, he thank me and said "THANK YOU! HAVE A GOOD DAY" I've never heard them talked even when they get stuck but it did! It was incredible. Noone on the school wanted to believe me. IF IT WEREN'T FOR THE VIDEO, NOONE WOULD BELIEVE ME. It was amazing
