He was a robot, but he wasn't devoid of feelings. And his main feelings were curiosity and eagerness - to socialise, of course. That's what the humans did. So that's what he should do too.
Grabbing his baton, he pointed at a kid he wanted to talk to, and they conversed.

He could see himself doing this forever.
SMRT-1 was a small purple robot character that appeared in Epcot's long gone Communicore attraction from 1982-1994. He was a demonstration for voice recognition technology and people talked to him from phones placed around him.
