This BUDDY robot we're about to tell you about was found at CES 2016 appearing to scurry around with a terrifying, sobbing face. That was when we first saw it. We later realized it was probably mad, maybe a little bit annoyed. He, if we're going to be so presumptuous as to give it a gender, seemed to be angered by the fact that he had to roll around the floor while his cohort, another robot, was allowed to sit on the table.
The one on the table was happy.
