figure. The findings appear in the journal, Science Robotics. Every year we're seeing more and more

robots in greater numbers of tasks and environments around our world.

And instead of just 20, 30, 40 years ago, when they were in manufacturing environments, you know,

building cars or painting things or stuff like that, more and more we're starting to see them in very social

context. So in retail environments, in care homes, in schools, and things like that. So robots

don't have the luxury of just being functional anymore. To engage with the humans, they also have

to be relatable. For example, imagine a robot helping out

in a care facility, delivering a meal or dropping off meds. You'd often see residents that would

refuse to eat their meal or they wouldn't want to take their medication that day. So you have a
